Economic Concerns Of Deepwater Completions And Workover Essay

Economic Concerns of Deepwater Completions and Workover. Benefits: Offshore completions and workover have some environmental benefits specially during the development phase. It offers less time over the hole, needs fewer resources, requires less capital equipment to develop a field. Subsea completions also is often associated with continuing availability during the production and disposal of equipment such as platforms, manifolds etc. Risks: Introduction: The environmental risks associated with offshore completions are similar to other oil and gas well drilling operations. Extemporaneous releases of hydrocarbons to the environment can occur during drilling or completion of the well. Macondo was not the first oil spill accident in offshore platforms, and will not be the last either. Oil spill is the main reason of environmental hazard with the flow of tons of oil into the sea water degrading marine and wildlife. While oil spilling is a regular phenomenon in the offshore industry (498 blowouts worldwide during 1970-2007), it not only affects the marine ecosystem, but also increases the water depth in the drilling area. Causes: a. Spills: With the growing expansion of deepwater platforms, new potential sources of spills must be addressed. These include extended well testing procedures (which may require offloading of oil to a barge), different oil storage requirements, new types of production facilities, and new methods of oil transportation from the well site to central
