"Does Manual Drilling Improve the Healing of Bone–Hamstring Tendon Grafts in Anterior Cruciate Ligament Reconstruction? A Histological and Biomechanical Study in a Rabbit Model." Orthopaedic Journal of Sports Medicine 8, no. 4 (2020): 232596712091160. http://dx.doi.org/10.1177/2325967120911600.

Background: Heat necrosis due to motorized drilling during anterior cruciate ligament (ACL) reconstruction could be a factor in delayed healing at the bone–tendon graft interface. Hypothesis: The process of osteointegration could be enhanced using manual drilling. It reduces the invasiveness of mechanical-thermal stress normally caused by the traditional motorized drill bit. Study Design: Controlled laboratory study. Methods: ACL reconstruction using semitendinosus tendon autografts was performed in 28 skeletally mature female New Zealand white rabbits, which were randomly divided into 3 groups. In group A (n = 12), the tunnels were drilled using a motorized device; in group B (n = 12), the tunnels were drilled using a manual drill bit; and group C (n = 4) served as a control with sham surgical procedures. The healing process in the tunnels was assessed histologically at 2, 4, 8, and 12 weeks and graded according to the Tendon–Bone Tunnel Healing (TBTH) scoring system. In addition, another 25 rabbits were used for biomechanical testing. The structural properties of the femur–ACL graft–tibia complex, from animals sacrificed at 8 weeks postoperatively, were determined using uniaxial tests. Stiffness (N/mm) and ultimate load to failure (N) were determined from the resulting load-elongation curves. Results: The time course investigation showed that manual drilling (group B) had a higher TBTH score and improved mechanical behavior, reflecting better organized collagen fiber continuity at the bone–fibrous tissue interface, better integration between the graft and bone, and early mineralized chondrocyte-like tissue formation at all the time points analyzed with a maximum difference at 4 weeks (TBTH score: 5.4 [group A] vs 12.3 [group B]; P < .001). Stiffness (23.1 ± 8.2 vs 17.8 ± 6.3 N/mm, respectively) and ultimate load to failure (91.8 ± 60.4 vs 55.0 ± 18.0 N, respectively) were significantly enhanced in the specimens treated with manual drilling compared with motorized drilling ( P < .05 for both). Conclusion: The use of manual drilling during ACL reconstruction resulted in better tendon-to-bone healing during the crucial early weeks. Manual drilling was able to improve the biological and mechanical properties of bone–hamstring tendon graft healing and was able to restore postoperative graft function more quickly. Tunnel drilling results in bone loss and deficient tendon-bone healing, and heat necrosis after tunnel enlargement may cause mechanical stress, contributing to a delay in healing. Manual drilling preserved the bone stock inside the tunnel, reduced heat necrosis, and offered a better microenvironment for faster healing at the interface. Clinical Relevance: Based on study results, manual drilling could be used successfully in human ACL reconstruction, but further clinical studies are needed. A clinical alternative, called the original “all-inside” technique, has been developed for ACL reconstruction. In this technique, the femoral and tibial tunnels are manually drilled only halfway through the bone for graft fixation, reducing bone loss. Data from this study suggest that hamstring tendon–to–bone healing can be improved using a manual drilling technique to form femoral and tibial tunnels.

Full textAbstract:
Drilling fluid plays an irreplaceable role in drilling operations, serving functions such as cuttings transportation, signal transmission, and wellbore stability maintenance. The measurement of drilling fluid rheological parameters is crucial for optimizing hydraulic rock breaking, precisely controlling bottom-hole pressure and wellbore stability, and ensuring wellbore cleanliness. Currently, manual measurement methods such as the Marsh funnel and six-speed rotational viscometer are commonly used on-site, but they suffer from long measurement cycles and significant human interference. The online drilling fluid rheology measurement device enables real-time, automated measurement of drilling fluid rheological properties, offering higher efficiency compared to manual methods. This study addresses errors arising from single measurement methods and proposes a combined approach for measuring drilling fluid rheological parameters, integrating both rotational and tube differential pressure methods, which complement each other. Additionally, techniques for improving the accuracy of rheological parameter measurements in an online drilling fluid measurement system are explored.

Full textAbstract:
Abstract Aluminum alloy is widely used in aircraft structural components. The high cutting force in the conventional machining often causes the burr formation in the machined parts. To overcome the problems, machining method with low cutting force are recommended. In this study, we attempted to mechanize the manual drilling (soft-machining) to establish a new drilling method with a small probability of burr generation. The thrust force in manual drilling is less than one-tenth of that in CNC machining. A total of more than 200 holes were drilled with the same drill at 35 to 110N of applied load. In the drilling of single plate, burr formation is related to the inclination of the drill exit surfaces. Even in the drilling of stacked plates, the soft-machining can drill the through holes at the specified points in all conditions. In the soft-machining, the level of load P[N] becomes an important parameter to minimize the damage generation and it may be a mandatory to adjust the load to the minimum level required for cutting and tool feed. Applying soft machining to robotic drilling may solve vibration problem.

Full textAbstract:
Borehole cataloguing is an important task in geological drilling. Traditional manual cataloguing provides the stratification of underground boreholes based on changes in core lithology. This paper proposes a novel borehole cataloguing method using a drilling process monitoring (DPM) system. This DPM cataloguing method stratifies a borehole according to the drilling speed through the rock. A 102 m borehole was drilled and cored in Baota district, Yan’an city, Shaanxi Province, China. The rock-breaking response parameters of the drill bit displacement, drill rod rotation speed and inlet pipe and outlet pipe oil pressures were monitored throughout the drilling process, and the drilling depth-penetration rate curve during the net drilling process was obtained. The changes in drilling speed show that the DPM cataloguing can identify the depths of the layer interfaces of the borehole and describe the stratification. The interface depth values obtained by DPM have little difference from the interface depth values obtained by manual cataloguing, and the errors are between −0.04% and 4.29%. From the DPM stratification results, the engineering quality evaluation of the rock mass can be realized without coring. DPM is fast, convenient, accurate, can greatly improve the efficiency of existing catalogues, and can be applied to scientific research in any underground space. DPM is a measurement-while-drilling technology. According to DPM data, the operating state of a drilling rig and the parameter changes while drilling can be obtained in situ and in real time throughout the drilling process.

Full textAbstract:
The rheology of drilling fluid is crucial for bottom hole pressure control, hydraulic fracturing, and wellbore stability. Currently, manual methods like rotational viscometers are used on drilling sites, which have long measurement cycles and are prone to human interference. Existing online measurement devices with pipe viscometers are affected by fluid pulsation from diaphragm pumps and motor vibrations, making it hard to accurately determine and monitor rheological parameters in real-time. To address these issues, this paper proposes a real-time optimization method for the rheological model of drilling fluid based on a pipe viscometer. First, the rheological model of drilling fluid and the calculation method for piep viscometer parameters were analyzed, and a pulsation interference suppression model for the pressure difference in the rheological measurement pipe based on empirical mode decomposition was established. Then, preprocessing and regression analysis of the drilling fluid rheological model were carried out, and a real-time optimization method based on univariate linear regression and the golden section search algorithm was constructed. Finally, an experimental platform for online monitoring of drilling fluid rheology using a single measuring pipe was set up. Experimental results show that the proposed method effectively suppresses pulsation interference on the pressure difference in the measuring pipe. The shear stress-shear rate rheological model curve of the drilling fluid better matches the manual rotational viscometer parameters compared to directly measured parameters. The real-time optimization accuracy of the drilling fluid rheological model exceeds 95%, significantly improving the real-time measurement accuracy of drilling fluid rheological parameters.

Full textAbstract:
Rock bolting is a commonly used method for stabilizing the surrounding rock in coal-mine roadways. It involves installing rock bolts after drilling, which penetrate unstable rock layers, binding loose rocks together, enhancing the stability of the surrounding rock, and controlling its deformation. Although recent progress in drilling and anchoring equipment has significantly enhanced the efficiency of roof support in coal mines and improved safety measures, how to deal with drilling rigs’ misalignment with the through-hole center remains a big issue, which may potentially compromise the quality of drilling and consequently affect the effectiveness of bolt support or even result in failure. To address this challenge, this article presents a robotic teleoperation system alongside a hybrid visual servo control strategy. Addressing the demand for high precision and efficiency in aligning the drilling rigs with the center of the drilling hole, a hybrid control strategy is introduced combining position-based and image-based visual servo control. The former facilitates an effective approach to the target area, while the latter ensures high-precision alignment with the center of the drilling hole. The robot teleoperation system employs the binocular vision measurement system to accurately determine the position and orientation of the drilling-hole center, which serves as the designated target position for the drilling rig. Leveraging the displacement and angle sensor information installed on each joint of the manipulator, the system utilizes the kinematic model of the manipulator to compute the spatial position of the end-effector. It dynamically adjusts the spatial pose of the end-effector in real time, aligning it with the target position relative to its current location. Additionally, it utilizes monocular vision information to fine-tune the movement speed and direction of the end-effector, ensuring rapid and precise alignment with the target drilling-hole center. Experimental results demonstrate that this method can control the maximum alignment error within 7 mm, significantly enhancing the alignment accuracy compared to manual control. Compared with the manual control method, the average error of this method is reduced by 41.2%, and the average duration is reduced by 4.3 s. This study paves a new path for high-precision drilling and anchoring of tunnel roofs, thereby improving the quality and efficiency of roof support while mitigating the challenges associated with significant errors and compromised safety during manual control processes.

We established a manual well-drilling pilot project based on the Water for All International drilling method in a small rural community in the Dominican Republic. Water testing for determining the level of biological and chemical contaminants was used to better assess the water needs of the community. For geophysical exploration, an experimental resistivity method and survey of existing wells provided information to better optimize the drilling location. With this information a pilot well site was selected in Tireo Abajo, and over the course of a week a 9 meter-deep well was successfully drilled, cased, and conditioned. The partner family and as many as 40 other members of the community helped to develop and implement this method during every stage of the process. This suggests the potential for a long-term development project that could benefit their community.

Fixture design for dedicated aircraft components is very challenging nowadays due to complexity, process capability, and effect on technical worker health conditions. The proposed fixture design for drilling an outer skin aircraft door will accommodate a design principle of fixture and ergonomic aspect of the technical worker. The proposed design will include the comfort drilling posture and finite element analysis (FEA) on the structure. The step required for the drilling process, starting from loading, locating, clamping, frame rotation, and hole drilling was discussed. FEA analysis shows a maximum value for the von Mises stress recorded was 6.373 × 105 N/m2 at the flange between the frame and vertical stand, and acceptable stress distribution results from the loaded weight of the outer skin aircraft door. A fully functional prototype was developed with a scale reduced to a quarter to verify the design. The developed prototype is successfully showing the capability of the fixture design in providing a mechanism of ergonomic consideration in the drilling of the outer skin of the aircraft door.

Full textAbstract:
In diversi paesi del mondo la situazione di accesso all'acqua (in termini di quantita' e protezione dalla contaminazione) e' ancora critica. In questo contesto UNCEF sta promuovendo la perforazione manuale (manual drilling) come una valida soluzione tecnica per aumentare l'uso delle acqua sotterranea.
"Manual drilling" indica un insieme di metodi di perforazione che utilizzano energia umana per la costruzione del pozzo. Queste tecniche sono piu' economiche delle perforazioni meccanizzate e facili da realizzare; Sfortunatamente pero' sono applicabili solo in zone con formazioni non consolidate e profondita' dell' acqua limitata.
La cartografia delle zone favorevoli e' stata realizzata in diversi paesi; il metodo adottato pero' ha un approccio qualitativo, dipendente dalla disponibilita' di dati presistenti e con un procedimento poco strutturato.
L'obiettivo di questa ricerca e' lo sviluppo di una metodologia per l 'identificazione delle zone favorevoli alle perforazioni manuali. mediante la integrazione di dati esistenti sui punti d'acqua con parametri derivati da telerilevamento e modellazione del terreno
Lo studio e' stato realizzato in due aree nel quadro del progetto "Use of remote sensing and terrain modeling to identify suitable zones for manual drilling in Africa and support low cost water supply", che ha visto partners di Italia, Senegal e Guinea.
La prima parte si e' concentrata sulla definizione di un modello concettuale semi-quantitativo per la stima della attitudine alle perforazioni manuali, basato sulla conoscenza di profondita' dell'acqua, della roccia, spessore di laterite e della trasmissivita' dell'acquifero superficiale.
Nella parte successiva si e' applicato questo modello concettuale alle due aree di studio. Per questo si sono realizzate le seguenti azioni:
1 - uno specifico software per la elaborazione dei dati dei pozzi e' stato sviluppato, sulla base della struttura dei database esistenti nei due paesi e della esperienza nel trattamento con il software TANGRAM all'Unversita' Milano Bicocca.
2 - Tramite la codificazione manuale e l'analisi automatica si sono stimati i parametri idrogeologici dello strato acquifero superficiale nei pozzi.
3 - Contemporaneamente si sono estratti:
• geologia, morfopedologia, tipo e copertura del suolo, ottenute da mappe tematiche esistenti;
• dinamica della vegetazione, della inerzia termica apparente e dell'umidita' del terreno, ottenute da analisi multitemporali di immagini satellitari MODIS (ottiche e termiche) e dati radar ASAR;
• parametri morfometrici otenuti da modelli di elevazione ASTER.
4 - Analisi multivariata per valutare le relazioni tra queste variabili e i parametri idrogeologici ottenuti dai dati dei pozzi; cio' ha permesso di estrapolare le informazioni sull' acquifero superficiale a tutta l'area di studio, identificando quindi le zone favorevoli.
I risultati principali sono le carte delle zone favorevoli alle perforazioni manuali che sono strumenti essenziali per la pianificazione dei programmi idrici di UNICEF e dei governi locali.
I metodo proposto permette di integrare livelli di informazioni disponibili in ogni regione che hanno mostrato relazioni significative con alcuni parametri fondamentali per la stima della attitudine alle perforazioni manuali (R2 = 0.73 con la profondita' dell'acqua in Senegal) e che quindi possono migliorare la ricostruzione del contesto idrogeologico a bassa profondita', specialmente in mancanza di dati diretti.
Inoltre il software TANGAFRIC potra' essere utilizzato per facilitare la organizzazione e interpretazione dei dati idrogeologici disponibili per altre regioni, rappresentando un valido supporto per le istituzioni locali.<br>In several countries of the World the situation of access to improved water sources (supplying an adequate quantity and protected from contamination) is still critical. In this context UNICEF is promoting manual drilling as a suitable low cost technical solution to increase the use of groundwater. Manual drilling refers to several drilling methods that rely on human energy to construct a borehole and complete a water supply. These techniques are cheaper than mechanized boreholes, easy to implement and able to provide clean water if correctly applied. Unfortunately manual drilling can be used only in areas where formations are quite soft and groundwater is relatively shallow. Mapping of suitable zones has been carried out in several countries in Africa, but previous methods are based on a qualitative approach, depending from availability of data and not structured. The main aim of this research is to develop an improved methodology for the characterization of shallow geological conditions and for the identification of suitable zones for manual drilling, by integrating the analysis of existing information from water point database with parameters derived from remote sensing and terrain modelling. This study has been carried out in two different areas, in Senegal and Guinea (West Africa), in the framework of the UK funded project "Use of remote sensing and terrain modeling to identify suitable zones for manual drilling in Africa and support low cost water supply", within the scientific cooperation of partners from Italy, Senegal and Guinea. The first part of the research focused in the definition of a well-structured and semi-quantitative conceptual model to estimate suitability for manual drilling, based on the knowledge of depth of water, depth of hard rock, thickness of lateritic layers and hydraulic transmissivity of shallow aquifer. In the second part this conceptual model has been applied in the two study areas A specific software (TANGAFRIC) to process borehole data has been elaborated, taking into consideration the existing water point database in both countries and the experience of stratigraphic analysis with software TANGRAM at University Milano Bicocca. Using TANGAFRIC with a procedure of manual codification of stratigraphic data and automatic analysis, it was possible to estimate hydro-geological parameters of shallow aquifer at borehole positions. In the mean time a set of variables have been obtained from three categories of data: - geology, geomorphology, soil and land cover, obtained from existing thematic maps; - vegetation phenology, apparent thermal inertia, and soil moisture, obtained from analysis of multitemporal optical and thermal satellite MODIS data and radar (ASAR) data; - morphometric parameters, obtained from public digital elevation models (ASTER GDEM). These variables have been combined using multivariate statistical methods in order to evaluate their relationship with hydrogeological parameters obtained from borehole data: this analysis allowed to extrapolate the information about geometry and hydraulic parameters of shallow exploitable aquifers with manual drilling from borehole position to the whole study area, and finally identifying those zones with potentially suitable conditions. The final result of this research was a comprehensive mapping of suitable zones for manual drilling in the regions under study. The maps thus produced are important tools for a correct planning of water programs by UNICEF and local institutions. The proposed methodology allows the integration of layers of information available in each region that show meaningful relation with those parameters required for the evaluation of suitability for manual drilling (R2 = 0.73 with groundwater depth in Senegal), therefore they can improve the interpretation of shallow hydrogeological context. Furthermore the software TANGAFRIC could be a valid support to local institutions for the organization and analysis of hydrogeological data.

碩士<br>國立高雄應用科技大學<br>模具工程系<br>97<br>This study aims to investigate the vibration modal characteristics of manual drilling machine, combined with experimental modal analysis and finite element analysis to carry out the model verification and discussion. The hammer impact serves as input condition, and signal measured by accelerometer serves as output condition from the machine structure in order to analyze experimental modal. The frequency response function is obtained by experimental measurement, and the modal parameters, such as natural frequencies, modal damping ratios and mode shapes, are obtained by using curve fitting software. Moreover, modal analysis and harmonic response analysis are conducted according to the numerical solution theory of finite element analysis to obtain the frequency response functions and structural modal parameters, including natural frequencies and mode shapes. Based on the modal parameters from experimental modal analysis, results obtained by two methods mentioned above are compared and verified in order to identify accuracy and reasonableness of theoretical model established by finite element analysis. The equivalent model established by analysis of the actual structure will be applied in frequency prediction analysis of drilling machine design.

Accurately grasping the distribution of different rocks can achieve the minimum explosive consumption and meet with the requirements of blasting quality; Not only reduces the cost of blasting, but also improves the safety and controllability of blasting. By utilizing the physical reactions to different rocks in the rigs process, the manual assisted learning process of the rig and the two stages of automatic drilling are proposed; After the automatic drilling, the lithology distribution of the borehole can be obtained in real time. The automatic drilling is the key to achieving fine blasting. Combined with the research of specific rigs and data processing methods. A KNN recognition model is established to construct the relationship between various indicators and lithology under certain confidence conditions, and this method can achieve automatic real-time adjustment and control of drilling parameters.

Full textAbstract:
Abstract The exact definition of all types of activities in well construction, from spud to completion, is an area of great challenges for an automation system to function successfully in. In an operation plan, these activities can be categorized into three subgroups: standard and repetitive sub-activities, customized sub-activities, and manual sub-activities. A digitalized detailed operation procedure (DOP) provides the appropriate context by defining the machine-readable version of these activities. Digitalizing a DOP is achieved by splitting it into individual parts, categorizing them into activities, checks, risks, lessons learned, best practices, and operational parameters and constraints. This paper focuses on manual sub-activities (e.g. close/open valves or nippling up) in which start and end time are acknowledged manually; pre-defined sub-activities (e.g. drilling and tripping) which are defined by repetitive tasks (e.g. drilling, lower string, lifting string and connections); and custom sub-activities (e.g. recording slack off and pick up weight or pressure tests) which can be customized for a tool, company, or operation with limited tasks (e.g. increase flowrate or reduce rotation). Adopting this approach guarantees:An unbroken consistency between the planned, executed and reported phases of an operation as the digitalized DOP is directly connected to the automation system and the detailed log of executed activities are recorded.Enabling automation of longer sequences as the rig state transition between activities is managed seamlessly. This also applies when it is interrupted by manual operations like making up casing hangers.Quality check and improvement of the automatically performed activities by using real-time models. This is not limited to the normal repetitive sub-activities such as drilling or tripping. They can be used for every related custom sub-activity, e.g., hydraulic modelling after the opening of a circulation sub or torque and drag calculations after releasing a liner running tool. Having a software library consisting of categorized, distinguishable manual and automatic activities lets the user describe with precision the operational tasks in a standardized digital format. With each automatic activity being readable and recognizable by the rig automation system, the system can execute longer and broader sequences of activities securely and cost-effectively, where the sequence is well defined.

A significant challenge in laser drilling is the optimization of process parameters and drilling strategies to achieve highquality holes. This is further complicated by the fact that quality assessment is a manual and time-consuming task. This paper presents a methodology designed to significantly reduce the manual effort required in optimizing parameters for single-pulse laser drilling of 0.3mm thick stainless steel. The objective is to precisely drill holes with an entry diameter of 70μm and an exit diameter of 20 μm, achieving high roundness. The features of the drilled holes were extracted automatically from the raw data using a combined approach that utilizes deep learning and image processing techniques. The outcomes were compared against manual measurements. Results indicate that the mean deviations between automated and manual measurements for both inlet and outlet diameters are less than one micrometer. We employed a Bayesian optimization algorithm to efficiently explore the parameter space without the need for incorporating expert knowledge. The approach rapidly identified optimal drilling parameters after only a few iterations, significantly expediting the optimization process and considerably reducing manual labor.

Abstract Unexpected situations and system failures during well construction operations are always possible. In the context of drilling automation, or even autonomous drilling, proper automatic management of these situations is of critical importance as the situation awareness of the human operator is very much reduced. The proper management of the transition between automatic and manual modes is necessary to improve the safety of automation solutions. An important characteristic of drilling automation solutions is their ability to cope with unexpected situations. This also encompasses, placing the drilling system in a state that is easy and intuitive for the human operator when manual control is required. Our approach to safe mode management is dependent on a good state estimation of the current conditions of the process. If for any reason, manual control must be regained, then the automated function itself triggers the necessary actions that will ensure a stable current state. In case of a drilling problem or a system failure, the human operator may have to regain control when the context might be totally different from the one left when the automation or autonomous function was enabled. It may even be a different human operator that has to take control, if a crew change has taken place. To make the transition from the automated/autonomous context to manual control, the automation/autonomous system sets the drilling machines in a so-called safe transition state. A safe transition state is one for which leaving the current setpoints of drilling machines untouched for a reasonable amount of time, will not immediately jeopardize the safety of the drilling operation. A safe transition state is contextual as it is not necessarily the same sequence of actions that must be performed to reach the safe transition state every time. The novel safe modes management method is integrated into existing drilling automation solutions. In a drilling automation context, the situation awareness of the human operator is considerably reduced as the automated functions control the process and the human operator is not actively driving the drilling machines. Without active safe mode management, there is a risk that drilling automation solutions may lead to serious situations as the driller may be totally unprepared to regain control in the middle of a critical situation. When it is needed to return to manual mode in the middle of the execution of an automatic procedure, an adequate procedure is executed. The choice of the procedure and its parameters depend on the current state of the process and system.

Full textAbstract:
Abstract Drilling process automation has been a trending topic within the technical community, most recently discussed in SPE-212565-MS (Cayeux et al. 2023). Recovery control - specifically in the case of motor stalls - is not only integral to consistently completing automation control system execution, but also building confidence for the control system users and ultimate automation benefactors. Predicting, preventing, detecting, mitigating, and recovering motor stalls through automated recovery control solves an issue affecting most operators, contributing to additional bottom-hole assembly (BHA) damage and unplanned trips. The recovery control system was designed with six major process control interfaces, two of which occur during on-bottom drilling: drilling while rotating and drilling while sliding. Each control interface is a means by which an external system can control the rig tools in a coordinated fashion, managing what control is currently active and ensuring the driller can ultimately assume control at any given time. The recovery control is customized and preconfigured with an observation window to execute the recovery process once the stall criteria has been breached while on-bottom drilling, sliding or rotating. The result is mitigated motor stalls that are consistently managed with a configurable automation system, less BHA damage, and no motor stall related unplanned trips - displaying both time and cost value. After two years of testing the recovery control system internally, there were no undetected stalls, no false detections, and no unplanned trips due to motor stall, displaying detailed accuracy. The recovery control complements the process control, limit control, and manual control components of the automation control system to drill a stand effectively and consistently. A complete and effective automation control system gives time back to the rig crew and allows for leadership development opportunities. The reliability gained through recovery control, faster than manual attempts, allows the driller to focus more time on safety and training the rig crew instead of monitoring differential pressure in the hopes of manually preventing a motor stall. In nearly all cases, stalls were detected faster with the automatic recovery control system compared to manual detection by the driller. Drillers cannot be expected to pay attention to the hundreds of potential drilling problems - a control system can. There are systems claiming to identify motor stalls, but this recovery control is the only technology to date that actively detects and recovers the system from the stall.

Abstract Having a good understanding of the offset wells is the key for successful planning and execution of any well, both from the risk management point of view as well as from equipment and operations planning. In both cases of congested or simple fields the amount of the manual work is significant, which further affected by potential human mistakes. The manuscript aims to provide the detailed explanation of the digitalization of the offset well risk analysis (ORA) implemented in several drilling projected, what lead to almost complete elimination of the manual work and allowed to improve the quality and the quantity of the offset data. At the project kick-off the manual work performed by different parties (drilling engineer as well as drilling fluid, directional, bits engineers etc.) was mapped in the different detailed workflows. This allowed to understand the final result of every tasks. As next step the massive database of the end of well reports, post-job reports, daily drilling reports, etc was created with few tens of millions entry points. Further the artificial intelligence in combination with data analytics was used to replicate the previously mapped workflows. As the result entire manual work was replaced by the digital, leading to receive higher number of outputs with superior quality. The direct benefit was a reduction of the time required to get the final result, when previously a detailed analysis was completed in 3 to 4 days, and now it is done within minutes, allowing to dedicate the man-hours to more other valuable tasks. The manuscript provides the novel information on ability to use digital technologies to eliminate manual work and avoid costly human mistakes. The proposed solution can be implemented in any other drilling project worldwide, as well as in any other activity requiring performance of the repetitive tasks.

Abstract Measuring the values of weight on bit (WOB) and differential pressure (DiffP) through accurate taring is critical for ensuring downhole tool health and creating accurate parameter roadmaps for drilling optimization. Current industry standards for taring rely on the driller to manually select a particular time when these values are zero, which is often imprecise and/or inaccurate. This paper will detail the journey this drilling contractor made to automate the taring process as part of a broader connection automation initiative, how initial solutions challenged organizational assumptions on downhole behaviors, and how a pattern recognition algorithm allowed for better tare consistency and accuracy over existing field procedures. An initial process automation procedure was designed and implemented in the rig control system (RCS) to manage the connection process, starting with coming out of slips and ending with tagging bottom. As part of this process, the system included a step to consistently tare when the drill bit is one foot off bottom and descending at a constant rate. During field trials, this method gave encouraging results over previous manual tares. Though the result did show improvement over the traditional manual taring method, discrepancies in the relationship between WOB and DiffP eventually led to an improved method of taring which utilizes a novel pattern recognition algorithm. This algorithm detects when the bit tags bottom and establishes a reference hookload (HKLD) at that point. A pattern recognition algorithm was included into the automation sequence replacing the step to tare one foot from bottom. The initial process automation routine provided consistency to the taring process which was observed during testing. The improvement in consistency revealed inconsistency in WOB tares which was supported by variance in DiffP when WOB was constant. A pattern recognition method was developed to identify when tagging bottom. This algorithm was applied to historical data providing evidence of its benefit to WOB tares. The algorithm was included in an application and then adapted and applied to DiffP tares. The application was run over a historical dataset to qualify its viability. After proving viability, it was exchanged with the taring step in the initial process automation routine and run on live wells. Taring using the pattern-recognition based application presented better results than the manual and initial automation taring methods. The overall operational impacts of each method will be discussed in further detail. The results of this project challenge underlying assumptions about how taring should be performed and improves overall understanding of the impact of different automation routines. The pattern recognition method discussed in this paper constitutes a novel application which utilizes new technology to improve existing processes.

Full textAbstract:
Abstract Invisible lost time (ILT) is a measure of inefficiency. Though not immediately apparent, it can be significant over the course of a drilling campaign. Much effort is dedicated to reducing ILT throughout the well construction process. Well construction is comprised of many subprocesses, each of which is an opportunity to reduce ILT with process optimization that can be realized with automation. Consistency through automation often provides insight to further refine and automate drilling processes. Well construction subprocesses are created by the drilling contractor and/or the operator, usually involving a detailed review. Processes such as applying or removing weight on bit (WOB), or zeroing the WOB, are critical to improving drilling performance and preserving the life of the bottom hole assembly (BHA). Once defined in detail, process automation facilitates precise and consistent execution. As drillers are trained, they transition from manual process execution to automation oversight, with insights from this automation utilization identify further opportunities for improvements. Applying, removing, or zeroing WOB are detailed processes with multiple machines moving simultaneously, occurring frequently during the well construction process. Because of this frequency, even seconds saved per event can potentially add up to days saved over the course of a well program. Consider the process of zeroing WOB in the lateral section. Often conducted at the end of a stand, it involves hoisting up a certain distance and rate, followed by lowering at a certain distance and rate, before deciding to zero the WOB. The specifics of how far and fast to hoist and lower are usually prescribed by the operator’s drilling personnel and were likely created before the process was automated. Manual execution of this process provides significant variability, leading to conservative process recipes. This process was automated, with a manual zero selection required for process completion. Opportunities to refine and improve the process became visible once replicated through automation. The most apparent observation was the lowering parameters could be optimized to reduce process time by 29%, as drillers are trained to make similar observations to improve efficiency of this process. A secondary observation is the optimized process can be automated to completely remove the manual zero selection step. This work will review the next phase of process automation and is complementary to prior work (SPE-217751-MS and SPE-222152-MS) that present the value of consistency and the role of digital transformation to improve process automation (Auld et al., 2024).

Full textAbstract:
Abstract This manuscript presents a comprehensive account of the development and experimental validation of an automated drilling fluid mixing system. This project is a joint technology venture between Equinor and Baker Hughes. The paper explains the critical aspects of designing an automation solution for a traditionally manual-oriented workflow. The system comprises a rig site software application for creating and managing mix sheets, a machine learning algorithm that suggests chemical mixes based on fluid properties, a real-time sensor system for monitoring fluid properties, and an OPC-UA communication protocol for sharing a digital mix sheet with automation hardware systems. The development of an automation system entails a comprehensive software application design that enables a gradual shift from manual to an automated workflow, fostering increased user confidence. The initial phase involved providing field engineers with the ability to manually create and organize the mix sheet. The second stage integrated a machine learning algorithm that allowed engineers to generate suggested mix sheets based on available products, current and target fluid properties. Once reviewed, the mix sheet is dispatched to an external automation solution for execution. Any changes made by the engineer to the suggested mix sheet are recorded to improve the algorithm. In the third phase, a real-time sensor system monitors and feeds data to the software, enabling the algorithm to generate a chemical mix in response to deviations or projected variations from target specifications. The use of OPC-UA communication protocol ensures versatility, scalability, and the seamless transmission of digital mix sheets to third-party automation systems. The automation software system was tested in drilling fluid automation lab of Equinor located at Sandsli Automatic Drilling Fluid Laboratory, Norway with three objectives: 1) Demonstrate the usability in rig and remote operations scenario, 2) Communication with rig automation system, and 3) Verifying the algorithm output. The testing proved the viability of using the application and a seamless transition from manual workflows to automation. This also demonstrated the ability of the application to support remote operation by lowering the workload and improve efficiency. A water-based fluid system was prepared at the lab for testing the algorithm output validity. The generated mix sheet was published to the OPC-UA server hosted in the application. The accuracy of the algorithm has already been verified earlier in a lab experiment. To conclude, the design of an automation system for the drilling fluid operations must consider the human factors, support rig and remote operations workflow and eventually capable of working in full autonomy. It must be able to communicate with other automation system via a standard, scalable and secure protocol like OPC-UA to ensure adoption. The solution developed for drilling fluid automation, the ML algorithm and communication methodology is novel in the industry and helps operators and service companies to improve service delivery quality, safety, and sustainability.
