TheMacondo oil rig explosion and subsequent oil spill was the worst disaster in the US offshore oil industry since 1969. Although some worried that it reflected the greater challenges of deepwater drilling for which the industry was not prepared, investigations have shown that a variety of decisions made, primarily during the drilling of the well, caused the blowout and explosion. Apparently, a corporate culture of cost cutting led to many of these decisions, and it suggests that human failures, both in senior levels where culture is set, and at the lower levels where it affects operations, are the primary challenges that need to be overcome to reduce the likelihood of future disaster.

ABSTRACT The China National Offshore Oil Corporation (CNOOC), established in October 1982, is the sole Chinese company dealing with offshore oil exploration, development, and production. It has four regional corporations, and four specialized corporations, as well as seventeen joint venture corporations. CNOOC has four representative offices outside China. Since the Sino-foreign cooperation for offshore oil exploration and development in China started, 360,000 line km of seismic survey have been shot, thirty-nine oil and gas bearing structures have been found, fifteen oil fields have been evaluated as having large hydrocarbon accumulations, nine oil fields have been developed and put into production, 179 exploratory wells have been drilled, and CNOOC has signed thirty-nine contracts with a total of forty-five foreign companies from twelve countries. There are five laws and regulations in the PRC affecting offshore oil development and marine environmental pollution. In accord with these laws and regulations, CNOOC has reviewed four environmental impact statements for offshore oil fields received from its regional corporations. CNOOC has made oil spill contingency plans for the Cheng-Bei offshore oil field in Bo-Hai, and the Wei 10-3 offshore oil field in the Gulf of Bei-Bu. Some oil spill combating equipment is owned by the Bo-Hai Oil Corporation and the Nan-Hai West Oil Corporation, selected on the basis of the crude oil characteristics.

Abstract With the continuous development of the global economy and industry, and gradually expand the size of offshore oil exploration and transportation, the possibility of oil field leakage, damage of offshore tanker, oil leakage of the offshore ship and the oil spill is increasing continuously, and the harmfulness is increasing continuously. It has seriously polluted the Marine environment and destroyed the ecological balance, and seriously wasted the oil resources. Therefore, this paper developed a kind of offshore oil spill removal ship which can quickly, accurately, and effectively recover oil spill. This paper designs an offshore oil removal device with a variable Angle of attack. Through the use of Rhino and SolidWorks modeling software for the three-dimensional overall design. The variable Angle of attack offshore oil spill removal ship can be divided into seven major systems, which are the main hull of the variable angle of attack, the side hull, the oil suction, and deoiling rollers, the oil collecting groove and oil collecting chamber, the oil baffle, the steering platform, the communication equipment, the propulsion equipment, the main hull, and the external ship docking equipment. At the same time, the new type of offshore oil absorption material is installed on the double roller oil absorption mechanism, and each component system of the offshore oil removal ship is assembled. In this paper, the design of a variable Angle of attack offshore oil spill removal ship can provide a reference for the research and design of a new offshore oil spill treatment device.

Abstract This publication presents how an oil asset unlocked idle production after numerous production upsets and a gas hydrate blockage. It also uses economics to justify facilities enhancement projects for flow assurance. Field F is an offshore oil field with eight subsea wells tied back to a third party FPSO vessel. Field F was shut down for turnaround maintenance in 2015. After the field was brought back online, one of the production wells (F5) failed to flow. An evaluation of the reservoir, well, and facilities data suggested that there was a gas hydrate blockage in the subsea pipeline between the well head and the FPSO vessel. A subsea intervention vessel was then hired to execute a pipeline clean-out operation, which removed the gas hydrate, and restored F5 well oil production. To minimise oil production losses due to flow assurance issues, the asset team evaluated the viability of installing a test pipeline and a second methanol umbilical as facilities enhancement projects. The pipeline clean-out operation delivered 5400 barrels of oil per day production to the asset. The feasibility study suggested that installing a second methanol umbilical and a test pipeline are economically attractive. It is recommended that the new methanol umbilical is installed to guarantee oil flow from F5 and future infill production wells. The test pipeline can be used to clean up new wells, to induce low pressure wells, and for well testing, well sampling, water salinity evaluation, tracer evaluation, and production optimisation. This paper presents production upset diagnosis and remediation steps actioned in a producing oil field, and aids the justification of methanol umbilical capacity upgrade and test pipeline installations as facilities enhancement projects. It also indicates that gas hydrate blockage can be prevented by providing adequate methanol umbilical capacity for timely dosing of oil production wells.

ABSTRACT In August and October 1980, two large oil spills occurred in the Arabian Gulf. The first, from an unidentified source, involved about 20,000 barrels of crude oil and impacted the entire north and west coasts of the island nation of Bahrain. The second occurred when the Ron Tapmeyer platform in the Hasbah offshore oil field blew out, releasing an estimated 50,000 barrels of thick crude into the Gulf. The spill subsequently covered large sections of the coastline of Qatar. The fate of the oil from these spills is examined with respect to the unique conditions found in the region. A computer model is used for trajectory analysis of the spills and hypothesizing the possible origin of the first spill. Methods of cleanup and problems with the weathered oil are mentioned. The environmental damage caused by the Bahrain spill is assessed.
