As the hunger for data grows, long stepouts become more common, and fiber communication becomes standard, the use of fiber in subsea oil and gas fields is set to increase. The paper provides a fast-track approach to perform screening assessment of multiple subsea concepts. Technologies are being developed that have the potential to support marine mining in all stages from prospection to decommissioning. When two engineers lost their jobs during the industry downturn, they used the misfortune as an opportunity to develop an innovative concept that aims to make it a lot easier to move subsea gas long distances. Currently, the state of the art for subsea well control is based on hydraulic technology.
With the purchase, the growing, privately-held Chrysaor Holdings will expand its UK North Sea production to 185,000 BOE/D. The state-run offshore company has found a gas and condensate field that holds an estimated 250 million BOE. The latest example of the offshore sector's march toward automated wellbore construction will take shape later this year in the North Sea. Just 2 months after issuing more than a hundred licenses, the Oil and Gas Authority begins the process again for a whole new set of blocks. The company announced it would “initiate the process” of marketing its UK Central North Sea fields as part of a portfolio review.
Africa (Sub-Sahara) San Leon Energy reported encouraging performance from its OML 18 field in Nigeria. Reperforation of an oil well increased gross field production to approximately 61,000 B/D before output was temporarily scaled back to 53,000 B/D for a shut-in, upgrade, and workover of the well. A number of other field wells will be reperforated in coming months, the company said. San Leon holds a 9.72% interest in the field, which is operated by Eroton (35%). Nigerian National Petroleum Corp. holds the remaining stake. FAR said that drilling has begun on the SNE-5 appraisal well offshore Senegal. The well and the following SNE-6 well will evaluate the upper SNE reservoir units' connectivity and deliverability by oil flow testing that will include interference tests.
Hurricane Energy reported that it believes the Greater Lancaster Area is a single hydrocarbon accumulation, which would make it the largest undeveloped discovery on the United Kingdom Continental Shelf. Operations on the 205/23-3A Halifax well were complete with the well leading to an oil discovery, the company said. Initial data analysis also indicated that the well is linked to the Lancaster field and forms a single large hydrocarbon accumulation. Preliminary third-party analysis of the well shows a "very significant" hydrocarbon column of at least 3,792 ft within the basement rock and it extends well below the local structural closure, Hurricane said. Following discussions with the UK Oil and Gas Authority, the company said the well has been suspended with future possibilities of deepening and/or further testing.
