Study on Wellbore Stability of Shallow Sediments in Deepwater Drilling
Method: In this paper, the shallow formation around the borehole is divided into plastic zone and elastic zone considering it under nonuniform in-situ stress. The collapse pressure formula of shallow formation is derived by taking the shrinkage rate of the borehole as the instability criterion. The fracturing pressure calculation model of shallow sediment under non-uniform in-situ stress is der...
متن کاملDesign and Installation of Deepwater Petroleum Pipelines
The exploration of offshore gas/oil has been moving to deepwater fields as big reservoirs have been found and technologies have improved. Presently, the most active areas in deepwater gas/oil field development are Africa and the GOM (Gulf of Mexico) in North America. There are many technological challenges in developing deepwater gas/oil fields such as: flow assurance, subsea systems, riser sys...
متن کاملDeepwater Drilling: Law, Policy, and Economics of Firm Organization and Safety
Although the causes of the Deepwater Horizon spill are not yet conclusively identified, significant attention has focused on the safety-related policies and practices—often referred to as the safety culture—of BP and other firms involved in drilling the well. This paper defines and characterizes the economic and policy forces that affect safety culture and identifies reasons why those forces ma...
