Abstract:

A significant increase of energy demands all over the world and production decline from available oil and gas reservoirs have led the industry to invest in major offshore petroleum resources. However, drilling operations in offshore environments are usually restricted by environmental constraints. Therefore, recent studies are devoted to the development of environmentally compatible fluids with adequate technical properties. Glycerine is a non-toxic, lubricating, colorless, odorless substance with a higher density than water. Due to the properties of glycerine, it can be used as the base of drilling fluid to formulate synthetic-based fluids. This research aimed to review the studies on the applications of glycerine in the composition of drilling fluid. Based on the results, glycerine-based fluids can be considered as an environmentally compatible fluid with sufficient technical properties to replace other drilling fluids. However, there is a lack of experimental studies on the glycerine fluid properties for a reliable decision. For the application of glycerine fluids, an economic feasibility study is mandatory for both pure and crude glycerine. Also, the thermal stability of glycerine fluids is an important aspect, which should be covered in future research studies.

Abstract:

Reversible emulsion drilling fluids can concentrate the advantages of water-based drilling fluids and oil-based drilling fluids. Most of the existing reversible emulsion drilling fluid systems are surfactant-based emulsifier systems, which have the disadvantage of poor stability. However, the use of modified nanoparticles as emulsifiers can significantly enhance the stability of reversible emulsion drilling fluids, but ordinary nanoparticles have the disadvantages of high cost and easily causing environmental pollution. In order to solve the shortcomings of the existing reversible emulsion drilling fluid system, the modified nanocrystalline cellulose was considered to be used as an emulsifier to prepare reversible emulsion drilling fluid. After research, the modified nanocrystalline cellulose NWX-3 can be used to prepare reversible emulsions, and on this basis, reversible emulsion drilling fluids can be constructed. Compared with the reversible emulsion drilling fluid stabilized by HRW-DMOB (1.3 vol.% emulsifier), the reversible emulsion drilling fluid stabilized by the emulsifier NWX-3 maintained a good reversible phase performance, filter cake removal, and oily drill cuttings treatment performance with less reuse of emulsifier (0.8 vol.%). In terms of temperature resistance (150 °C) and stability (1000 V < W/O emulsion demulsification voltage), it is significantly better than that of the surfactant system (temperature resistance 120 °C, 600 V < W/O emulsion demulsification voltage < 650 V). The damage of reservoir permeability of different types of drilling fluids was compared by physical simulation, and the damage order of core gas permeability was clarified: water-based drilling fluid > reversible emulsion drilling fluid > oil-based drilling fluid. Furthermore, the NMR states of different types of drilling fluids were compared as working fluids, and the main cause of core permeability damage was the retention of intrusive fluids in the core.

Fuzzy ball drilling fluids have been developed in order to effectively control lost circulation during CBM drilling. Depending upon fuzzy balls and colloids in fuzzy balls, the fuzzy ball drilling fluids changed their shapes and properties to completely plug underground heterogeneous seepage channels so as to strengthen the pressure bearing capacity of formations. This paper describes the available features of the fuzzy ball drilling fluid including efficient plugging, good carrying and suspension, formation damage control, compatible weighted by any weighted materials without auxiliary equipment.

Abstract:

The critical functions performed by drilling fluids during drilling operations include providing hydrostatic pressure to prevent formation fluids from entering into the wellbore, keeping the drill bit cool and clean during drilling, carrying out drill cuttings, and suspending the drill cuttings while drilling is paused. Others include control of formation pressures, prevent well-control issues, maintaining wellbore stability, minimize formation damage, cuttings transport from the wellbore to surface and minimize risk to personnel, the environment and drilling equipment. In adverse drilling environments such as High Pressure High and Temperature (HPHT) wells, the elevated temperatures and pressures encountered by the drilling fluids downhole may limit their technical performance and result in drilling problems if these factors are not well considered during the drilling fluid design. Hence, the objective of this study is to carry out a gap analysis on the performance of conventional drilling fluids in high pressure and high temperature environments using appropriate engineering methods. The outcome of the study identified some of the limitations of drilling fluids in HPHT drilling environment such as loss of rheology property control, fluid gelation at high temperature, high fluid loss at HPHT conditions, thermal degradation of the drilling fluid constituents, sagging of weighting materials etc. Benchmarks such as thermal stability of drilling fluid products and system, resilience to high temperature gelation, resistance to high temperature fluid loss, stable rheological properties control, resistance to solids sagging in HPHT environment etc were identified as top criteria for optimal performance of drilling fluids systems in HPHT wells. Potential steps or actions that that may be taken to bridge the existing gaps or shortcomings of conventional drilling fluids in HPHT drilling environment were then recommended.

Abstract:

An important aspect of hydrocarbon drilling is the use of drilling fluids that remove cuttings and stabilize the wellbore, providing better filtration. The properties of drilling fluids are essential to the success of any drilling operation. Fluids were originally developed to enable and cost effectively rotary drilling in subterranean formations. In addition, drilling fluids were designed to form a filter cake, which was primarily designed to reduce filtrate loss to the formation, was thin, and retained the drilling fluid in the wellbore. One of the most important functions of drilling fluids is to minimize the amount of drilling fluid filtrate entering a hydrocarbon containing formation, which can cause damage to the formation due to changes in rock wettability, fines migration, mud plugging with solids, and formation water incompatibility. To stabilize these properties, a number of additives are used in drilling fluids to ensure satisfactory rheological and filtration properties of the fluid. However, the commonly used additives are hazardous to the environment: when drilling fluids are disposed of after drilling operations, they, together with drill cuttings and additives, are discharged into water bodies and cause unwanted pollution. Therefore, these additives should be replaced with additives that are environmentally friendly and provide superior performance. In this regard, biodegradable additives are needed for future research. The review article presents an investigation into the role of various biowastes as potential additives for use in water-based drilling fluids. The use of waste-derived nanomaterial was considered, and rheological and filtration studies of water-based drilling fluids were carried out to evaluate the effect of waste additives on the performance of drilling fluids.

Abstract:

The rheological property of the drilling fluid was one of the focus problems in deep-water drilling, which was widely concerned. In the article, the viscosity-temperature properties of commonly used water soluble polymeric solution, polymeric brine solution, bentonite slurry, polyacrylamide-potassium chloride drilling fluid with different densities and water-base drilling fluid systems commonly used for China offshore well drillings were studied. 4°C-to-20°C viscosity ratio and 4°C-to-20°C YP ratio were used to judge the thickening level of drilling fluids due to low temperature. The experimental results show that on the condition of without considering the influence of pressure on the rheological property of water-base drilling fluid, its viscosity and yield point raised obviously with the decrease of temperature, but the increase level is proximately the same, its 4°C-to-20°C apparent viscosity ratio is basically within the 1.50. Analysis indicates that the viscosity of water-base drilling fluid depends on the viscosity of dispersed media. The performance of water medium determines the viscosity-temperature property of the water-based drilling fluid. It is proposed that in deep water drillings, if a water-base drilling fluid is used, it is not necessary to emphasize the influence of deep water and low temperature on the flowability. On the condition of guaranteeing wellbore stability and borehole cleaning, it is more suitable for using the water-base drilling fluid with low viscosity and low gel strength for deep water well drillings.

Abstract:

Via discussing the advantages and disadvantages of different types of oil-based drilling fluids, the main reason why oil-based drilling fluids are less used in our country is obtained that dont form a complete series of matching technology. The essence of wellbore instability caused by using water-based drilling fluids to drill shale is analyzed that the formation collapse pressure is greater than drilling fluids column pressure. The fundamental way of controlling borehole wall stability that use water-based drilling fluids to drill shale horizontal well was proposed that deeply researched the shale hydration mechanism, developed efficient blocking agent and inhibitors and established shale gas drilling fluid suppression system, which made water-based drilling fluids have excellent performance.

Abstract:

One of the most important tasks when drilling a borehole is to select the appropriate type of drilling fluid and adjust its properties to the borehole’s conditions. This ensures the safe and effective exploitation of the borehole. Many types of drilling fluids are used to drill holes for crude oil and natural gas. Most often, mainly due to cost and environmental constraints, water-based muds are used. On the other hand, invert drilling fluids are used for drilling holes in difficult geological conditions. The ratio of the oil phase to the water phase in invert drilling fluids the most common ratio being from 70/30 to 90/10. One of the disadvantages of invert drilling fluids is their cost (due to the oil content) and environmental problems related to waste and the management of oily cuttings. This article presents tests of invert drilling fluids with Oil-Water Ratio (OWR) 50/50 to 20/80 which can be used for drilling HPHT wells. The invert drilling fluids properties were examined and their resistance to temperature and pressure was assessed. Their effect on the permeability of reservoir rocks was also determined. The developed invert drilling fluids are characterized by high electrical stability ES above 300 V, and stable rheological parameters and low filtration. Due to the reduced content of the oil, the developed drilling fluid system is more economical and has limited toxicity.

Abstract:

Abstract Drilling fluids perform a number of important functions during a drilling operation, including that of lifting drilled cuttings to the surface and balancing formation pressures. Drilling fluids are usually designed to be structured fluids exhibiting shear thinning and yield stress behavior, and most drilling fluids also exhibit thixotropy. Accurate modeling of drilling fluid rheology is necessary for predicting friction pressure losses in the wellbore while circulating, the pump pressure needed to resume circulation after a static period, and how the fluid rheology evolves with time while in static or near-static conditions. Although modeling the flow of thixotropic fluids in realistic geometries is still a formidable future challenge to be solved, considerable insights can still be gained by studying the viscometric flows of such fluids. We report a detailed rheological characterization of a water-based drilling fluid and an invert emulsion oilbased drilling fluid. The micro structure responsible for thixotropy is different in these fluids which results in different thixotropic responses. Measurements are primarily focused at transient responses to step changes in shear rate, but cover also steady state flow curves and stress overshoots during start-up of flow. We analyze the shear rate step change measurements using a structural kinetics thixotropy model.

Abstract:

Drilling fluids make up an essential part of the drilling operation. Successful drilling operations rely on adequate drilling fluid quality. With the development of new drilling techniques such as long deviated sections and drilling in ultra-deep waters, the standard of required performance of the drilling fluids continue to increase. Narrow pressure margins and low tolerance for barite sag requires accurate prediction of the gel evolution in drilling fluids. Increased knowledge of how drilling fluids behave during low shear rates can lead to better design of drilling fluids to avoid settling of heavy particles at the wellbore. Settling of heavy particles at the wellbore can lead to serious incidents such as stuck pipe, lost circulation, poor cement jobs and well control difficulties. Studies on the gel evolution of oil based drilling fluids could be used to optimize hydraulic modelling and evaluate phenomena such as fluid loss, barite sag and cuttings transport.The objective of this report was to investigate the gel evolution, low shear viscosity and viscoelastic properties of oil based drilling fluids. Literature study and experimental investigations were performed on water based and oil based drilling fluids to extend the understanding of low shear viscosity of oil based drilling fluids.Literature study performed on low shear viscosity of drilling fluids confirmed that there is a need for improved models for describing dynamic yield point and low shear behaviour. A case study performed illustrates the relevance of the topic, and the consequences unexpected gel effects could have when drilling a well. Two water based drilling fluid samples and one oil based drilling fluid sample were prepared and tested. Quantitative information about the dynamic properties of drilling fluids was found. Flow curves and gel strength were measured using a Fann viscometer. Four different drilling fluid samples were investigated using an Anton Paar Physica rheometer. Oscillatory tests such as amplitude sweeps determined linear viscoelastic range (LVE). Determination of the linear viscoelastic range was necessary to further investigate viscoelastic properties by performing frequency sweeps within the LVE range. Both amplitude sweeps and frequency sweeps were performed at different frequencies and strains. The viscoelastic properties investigated were structure formation, structure breakage and low shear viscosity. The effect of variables such as temperature, frequency, time of rest on dynamic yield point and viscous and elastic modulus was investigated by varying these variables in series of experiments. Experiments performed conclude that there is little correlation between the dynamic yield point found from extrapolation of flow curves using the Herschel Bulkley model and the Bingham plastic model, and the dynamic yield point found from amplitude sweeps. Amplitude sweeps showed that the three samples of drilling fluids exhibit viscoelastic behaviour, and that the linear viscoelastic range in strain rate was approximately 1 % at a temperature of 20 °C and a frequency of 1 s-1 for all tested samples. Frequency sweeps showed that the elastic modulus dominates the viscous modulus within the LVE range for all three samples. Linear viscoelastic range and dynamic yield point were found to be temperature and frequency dependent. The properties of the different samples were found to not change monotonically with frequency or temperature. Results of experiments performed on a model water based drilling fluid conclude that time of rest had little influence on the properties even for longer period of rest. A slight increase in viscosity was observed for longer rest periods.

Abstract:

The objective of this master thesis was to investigate the flow properties of water based drilling fluids, utilizing measurements in both the micro and macro scale. The research was performed on two realistic drilling fluids by the use of a viscometer, a rheometer and a realistic flow loop, where the latter represents the macro scale. The research outcome could possibly improve the understanding of flow behavior in wellbores, and remove uncertainties associated with annular friction. The two fluids utilized in the research was made up with the goal of having equal rheological qualities, when measured with a Fann 35 viscometer. A more thorough examination of the two fluid's rheology was then executed by using a Anton Paar MCR302 rheometer. The macroscopic properties was researched employing a flow loop, capable of simulating realistic wellbore conditions.The main outcome of this thesis is that even though two fluids appear to have the same rheoligical properties when measured on simple equipment, their fundamental different microscopic structure will exhibit variations when the fluids are utilized in real applications.Due to problems encountered when mixing the fluids, as well as problems with one of the fluids itself, not all intended experiments were conducted. The experiments should be replicated with an emphasis on temperature control, avoiding bubbles and foam, and be conducted within a shorter time period.

Abstract:

This thesis reports an experimental and theoretical study on filtration properties of water based drilling fluids under dynamic and static conditions. The tested muds cover Freshwater/Gypsum/Lignosulphonate mud and SeawaterlKCLlPolymer mud, bariteweighted and unweighted. The effects of the solid concentration, pressure and shear rate on the filter cake characteristics and the erodability were investigated. For static filtration experiments, all tests were conducted for two hours and the spurt loss, the filter cake thickness, the ratio of wet to dry cake mass and the cumulative filtrate volume against time were measured. For dynamic filtration experiments, however, only the spurt loss and the cumulative filtrate volume against time were measured and all tests were conducted for at least 8 hours. A general filtration equation was developed based on the cake filtration theory prevailing in the chemical engineering industry and it was utilised to obtain the modified classic static filtration equation and the dynamic filtration equation. The modified classic static filtration equation was then employed to fit the static filtration experimental data and the average specific static cake resistance and the effective filter medium resistance were calculated. The dynamic filtration equation showed a substantial agreement with the dynamic filtration experimental data. Using the static filter cake properties such as the ratio of wet to dry cake mass (m), the average specific dynamic cake resistance, the effective filter medium resistance and the dynamic filter cake erodability were calculated. In the study of the relationship between the static filtration data and the dynamic filtration data, an attempt of predicting the dynamic filtration data from the static filtration experimental data was conducted. Also, an attempt was carried out to predict the static filtration data and the dynamic filtration data in a sequential process. The experimental data suggests that a substantial difference exists between the specific resistances of static and dynamic filter cakes. No apparent distinction was found, however, between spurt loss and effective filter medium resistance. The reodability of dynamically deposited mud cake for Seawater/KCL/Polymer mud was found to be three fold for Freshwater/Gypsum/Lignosulphonate.

Abstract:

Accurate determination of the pressure losses at the bit is very important for drilling practices in petroleum industry. In the literature, there are several studies on determination of the pressure losses. Major focus is concentrated on single phase drilling fluids, which is far from accurate estimation of pressure losses for multiphase fluids, i.e., fluids including a liquid and a gas phase, at the bit. Some of these models are valid for multiphase fluids, however, they are either valid for very high gas flow rates, or developed using very strong assumptions. This study presents a mathematical model for calculating bit hydraulics for gasified drilling fluids. The theory, which is valid for both sonic (critical) and subsonic (sub-critical) regimes, is based on the solution of the general energy equation for compressible fluid flow. The model is sensitive to changes in internal energy, temperature and compressibility. In addition, the model uses &ldquo
mixture sound velocity&rdquo
approach. A computer program is developed based on the proposed mathematical model. The program calculates pressure drop through a nozzle in subsonic flow region, and suggest flow rate if the calculated pressure drop values is in the sonic flow pressure ranges. The program has been run at reasonable field data. The results of the models have been compared with the results of existing models in the literature. The results show that the pressure losses through the bit can be estimated with a variation less than 9%. Also, it has been observed that bottom hole pressure, velocity of the liquid phase and nozzle size have a strong influence on bit pressure drop.

Abstract:

The increasing requirements of drilling fluids in long extended reach wells desires for new solutions to solve torque and drag problems in the wellbore. Nanotechnology is an upcoming technology development, which is already used in other industries to minimize friction coefficients of lubrication fluids in hydraulic hoses. Drilling fluids act also as a lubrication fluid in the wellbore, besides of many other functions it has to fulfill. It is well known that oil based muds (OBM) are characterized with a better lubrication efficiency than water based muds (WBM). Out of this reason, research interest increases about successfully implementing nanoparticles to drilling fluids, especially to WBM, for reducing the generated mechanical friction between drill string and casing. Within this framework of thesis, tribological and rheological experiments were performed to investigate whether friction reduction can be achieved with alumina, titania or silica nanoparticles. Different particle concentrations in the fluid were tested to see, if lubrication efficiency can be defined to a specific particle concentration. Additionally, the nanoparticle added fluids were tested under different temperature condition to determine the influence on temperature towards nanoparticles. The experimental phase of the thesis was performed with a pin-on-disk apparatus and a modular compact rheometer (MCR), which allowed tribology and viscosity measurements. The tribology experiments test the metal to metal friction factor, which depend on the lubrication effect of the fluid. The rheology apparatus measures the viscosity of the fluid under different temperatures according to the standardized Fann viscometer.Whereas the pin-on-disk apparatus has an internationalized procedure manual and the test results are assumed to be reliable.As major result, there is a coupling effect between temperature and nanoparticles in the fluids. With the results of the pin-on-disk apparatus, the titania and silica nanoparticles effectively reduced the friction factor. The alumina particles have a limited friction reduction, in consequence of an increasing friction factor with increasing particle concentration in the fluid.

Abstract:

The studies conducted on hole cleaning have been started with single phase drilling fluids for vertical holes in 1930&rsquo
s, and have reached to multiphase drilling fluids for directional and horizontal wells today. The influence of flow rate and hole inclination on cuttings transport has been well understood, and many studies have been conducted on effective hole cleaning either experimentally or theoretically. However, neither the hydraulic behavior nor the hole cleaning mechanism of gasified drilling fluids has been properly understood. The aims of this study are to investigate and analyze the hole cleaning performance of gasified drilling fluids in horizontal, directional and vertical wells experimentally, to identify the drilling parameters those have the major influence on cuttings transport, to define the flow pattern types and boundaries as well as to observe the behavior of cuttings in detail by using digital image processing techniques, and to develop a mechanistic model based on the fundamental principles of physics and mathematics with the help of the experimental observations. A mechanistic model is developed with the help of the obtained experimental data. Developed model is used for estimating optimum flow rates for liquid and gas phases for effective cuttings transport as well as for determining the total pressure losses and void fraction of each phase for a given drilling conditions. The v mechanistic model obtained using the experimental data within the scope of this study will be used to develop the hydraulic program and equipment selection to be used in the field during underbalanced drilling applications.

Abstract:

Abstract The drilling fluid is the primary barrier against well control incidents when drilling a well in conventional mode and the drilling fluid properties must be correct at all times to prevent well control incidents. Automatic drilling fluid monitoring through automated measuring techniques combined with real time data transfer into control center with 24/7 surveillance substantially improves this control compared to conventional methods relying on manual measurements with long sampling intervals. New measurement devices have been introduced to the industry which measure the drilling fluid properties of all fluid going into the well as well as fluid coming out from the well. Properties measured are among others density and a full rheology profile. The data are transferred to users on the rig as well as directly to onshore operation centers. This highly improves the fluid engineering, enabling a more precise diagnostician and treatment in real time. This also improves efficiency when performing displacements from one fluid system to another. This paper will present new units for automatic drilling fluids measurements and its use in offshore drilling. The surveillance of fluid properties and the use of data at an onshore operation center will be presented. The drilling fluid properties are also detrimental for drilling parameters such as ECD (equivalent circulating density), surge and swab pressures and hole cleaning properties and the added data will improve any estimation of such parameters. The paper will present experiences from use of these data into advanced real time hydraulic measurements and models for automatic drilling control and explain how this can improve safety in the drilling operations as well as improve the drilling efficiency.

Abstract:

Drilling fluid plays a key role in the installation of a pipeline by horizontal directional drilling (HDD) and accounts for the majority of the associated environmental impact. An improper drilling fluid program can result in stuck pipe. Uncontrolled discharge of drilling fluid downhole can damage or undermine adjacent structures.The cost of drilling fluid involved with pipeline installation, particularly when disposal costs are considered, can be substantial. This manual is the principal product of PRC project PR-227-9321. Its purpose is to increase the level of technical sophistication relative to drilling fluids used in the installation of pipelines by Horizontal Directional Drilling (HDD). It is anticipated that this increase will benefit the natural gas industry through reductions in HDD installation costs and environmental impact. The manual contains six sections which address the following general topics: 1 . The HDD installation process, the specific functions of drilling fluids in pipeline installation by HDD, and the composition of drilling fluids; 2. Characteristics of drilling fluid flow, pertinent properties of drilling fluids, and calculation methods relative to drilling fluid flow circuits; 3. Standard classification of soil and rock structures and soil and rock properties relative to drilling fluid flow; 4. The behavior of soil and rock structures relative to drilling fluid flow, general drilling fluid criteria, and general solutions to drilling problems; 5. Methods for estimating drilling fluid quantities, methods for disposing of excess drilling fluids, the environmental impact of drilling fluids used in HDD, and construction specifications relative to drilling fluids; and 6. Materials used drilling fluids.
