  • Drilling Muds and Drill Cuttings Recovery for Beneficial Reuse

    Drilling Muds Drilling mud, also known as drilling fluid, is a vital component of the drilling process. It helps in the process of drilling boreholes into the earth where holes are required for extraction of oil and gas, core sampling and various other purposes. It is broadly of three types, including water-based, oil-based, and synthetic-based. Among all of these, synthetic-based muds ...

  • Leakage from drill pipe casing subject to shear deformation

    The possibility of fluids leaking from a pressurised drill pipe casing subject to shear deformation caused by various events, including geological activity (such as seismic activity or deformations associated with subsidence related to excavation and construction) in the vicinity of the bore hole, is investigated. An experimental laboratory scoping investigation has been conducted to determine ...

  • A new sustainability model for machining processes

    It is generally recognised that the sustainability concept integrates economic, environmental and social aspects. It would be interesting for manufacturers to be able to know which process, workpiece materials or machining condition is more sustainable than another. In this paper, a new model for the sustainability in the machining field is proposed with the goal to increase productivity, reduce ...

  • Experimental study of the effect of temperature on the flow behaviour of oil-based muds in Niger delta formation

    The behaviour of the drilling fluids under high temperature is extremely important for drilling deep wells. Most commercial oil-base drilling fluid systems have limitations such as reduced rheology and filtration control if the fluid is exposed to higher temperature for prolonged periods of time. Formulating a drilling fluid system that can adequately withstand drilling in a high temperature ...

  • Effects of Borehole Fluid on Standard Penetration Test Results

    The standard penetration test (SPT) represents the most widely used in-situ test method for evaluating the liquefaction resistance of saturated soils. Significant progress has been made in recent years in developing correlations between SPT results obtained using different test procedures and equipment in order to develop a higher degree of standardization for SPT testing. One of the heretofore ...

  • Trends in plug and abandonment cost in the Gulf of Mexico, 2002?2007

    Wells are drilled to explore for, delineate and produce hydrocarbon reservoirs. At the end of their useful life, wellbores are permanently abandoned in a process known as Plugging and Abandonment (P&A). The purpose of P&A is to prevent the migration of fluids from the wellbore and establish a permanent barrier to the existing geologic formation. In this paper, we assess trends in P&A costs in the ...

  • Removal of hydrogen sulfide by zinc oxide nanoparticles in drilling fluid

    Hydrogen sulfide is a very dangerous, toxic and corrosive gas. It can diffuse into drilling fluid from formations during drilling of gas and oil wells. Hydrogen sulfide should be removed from this fluid to reduce the environmental pollution, protect the health of drilling workers and prevent corrosion of pipelines and ...

  • How to economically evaluate a drilling fluid plant? A systematic approach

    As the results of government initiative to increase production, large number of wells are planned to be drilled in the next few years. As a consequence of this, huge volumes of drilling fluid are dumped or disposed into land. To maximise savings of drilling fluid, this study aimed to investigate if it is economically viable to set up a drilling fluid plant. This study provides consistent and ...

  • Fearless flow back - treating completion fluids & acid flow backs

    An oil company completed a well and CETCO Oilfield Services was there to treat the flow back fluids. During the flow back, it was necessary for the oil company to continue normal drilling operations. Deck space on the structure was at a premium for the oil company, who simultaneously continued drilling while flow back fluids were being treated. CETCO Oilfield Services’ proven technology and ...

  • Water reclamation from shale gas drilling flow-back fluid using a novel forward osmosis–vacuum membrane distillation hybrid system

    This study examined the performance of a novel hybrid system of forward osmosis (FO) combined with vacuum membrane distillation (VMD) for reclaiming water from shale gas drilling flow-back fluid (SGDF). In the hybrid FO-VMD system, water permeated through the FO membrane into a draw solution reservoir, and the VMD process was used for draw solute recovery and clean water production. Using a SGDF ...
