Abstract:
Easily accessible oil reserves are currently decreasing, leading to an increase in more complex offshore deep-sea drilling programs, which require increasingly greater depths to be drilled. Such wells are commonly drilled using oil based muds, which leads to the production of drilled rock fragments, drill cuttings, which are contaminated with the base oil present in the mud. It is a legal requirement to reduce oil content to below 1 wt% in order to dispose of these drill cuttings in the North Sea and microwave processing is suggested as a feasible method of achieving the desired oil removal.

Abstract:
Analytical techniques applicable to the assay and remediation of cutting/mud matrices have been developed, utilising soxhlet extraction with dichloromethane and a drying agent followed by analysis using Gas Chromatography (FID). Calibration curves of oil content were produced for Novatec and Versaplus coated cuttings that were also sized by wet and dry sieving techniques, demonstrating their variable nature. The oil in each size fraction was assessed and showed that the finer fractions preferentially adsorbed the oil. Bacteria were isolated from the cuttings, muds and the pure oils to see if a

Contaminated waste drill cuttings produced from drilling activities in the North Sea is currently transported onshore and landfilled at high costs, as there is no existing option for alternative and viable recycling.

In this project, three samples of waste drill cuttings were obtained and characterised for chemical compositions, mineralogy, thermal behaviour and contaminant leaching. To manu

Abstract:
Oil production in the North Sea sector pre-1990 used predominantly oil-based drilling muds. The drill cuttings still contained significant amounts of muds and associated hydrocarbons despite cleaning prior to disposal onto the seabed. The cuttings accumulating on the seabed caused physical smothering and toxic effects of the hydrocarbons or other constituents of the muds. Although decreases in hydrocarbon levels have been observed over 10 years, it has been difficult to distinguish whether this 'decrease' is due to natural attenuation or whether it is an artefact of the sampling methods.

Abstract:
The objective of this research was to design a pilot scale continuous supercritical fluid extraction (SFE) system for the treatment of drill cuttings.The design includes: • A Piping and instrumentation diagram (P&ID) • A control philosophy • An operation manual, and • A HAZOP analysis The pilot scale SFE system was designed using a HAZOP-inspired framework, which resulted in the inclusion of risk reducing measures. This design approach was appropriate for the design of a novel technology, as risk reduction was made the inherent priority throughout the process. No major changes were made

碩士<br>國立成功大學<br>機械工程學系碩博士班<br>95<br>Drilling is one of the most important machining processes that have been widely applied in manufacturing area. According to the statistics, the capital spending of drills is over forty billion US dollars per year in the world. Drills are usually reconditioned four or more times. Therefore, the OEM is only responsible for about 20 percent of a drill’s cutting-edge life. That means the reconditioning service is responsible for 80 percent. In the past, drills were manually reground. Compared with references of drill design, the existing literature addressing

Abstract:
Drilling is one of the most important and common machining operations carried out in manufacturing industry. In drilling, the parameters such as hole-roundness, location and size, and interior surface finish are important for the proper functioning in the assembly. All of these parameters are related to the orbital motion of the drill during the drilling operation, which mainly arises from the lateral vibrations of the twist drill in a plane. In order to understand the dynamics of the process during drilling, a simplified two-dimensional model for the transverse motion of the drill rotating in

Abstract:
This thesis originally proposes an improved theoretical method to predict thrust and torque of twist drills in high speed drilling. The three existing models and methods are thoroughly studied and evaluated. It has been observed that each method has its own advantages as well as drawbacks and some errors. A fundamental geometrical analysis is carried out on the primary cutting edge of a twist drill to understand the correlation between the geometrical features of the drill and the distribution of cutting forces. The improved method is based on the representation of the cutting forces along th

Abstract:
Continuous models for a fluted twist drill are developed to study its static and dynamic bending characteristics. The static model is numerically simulated within Matlab for point loads at the free end of a twist drill. The bending curves are plotted and the bending stiffness of a twist drill is estimated. Effect of orientation of the spirally fluted cross-section at the fixed end on end deflection is studied. Characteristic bending curves for one pitch length of drill are plotted and region of minimum deflection is identified. Dynamic model is numerically simulated in Matlab over a range of

Abstract:
Improvement of manufacturing productivity is dependent on the successful automation of manufacturing processes, the success of which is based in turn upon the availability of information which describes the state of manufacturing operations. Acoustic Emission (AE) signals related to the cutting process and tool wear have been recently applied to monitor manufacturing processes, and various AE parameters can be used to provide process information. For example, when cutting tools become worn, AE energy generated at the interface of tool flank and work piece increases. This study is thus an exper
