Al Shaheen Oil Field

The Al Shaheen Oil Field is a production oil and gas field off the north east coast of Qatar in the Persian Gulf, north of Doha. The oil field lies over the North Gas Field, one of the largest gas fields in the world. The field has been operated by Maersk Oil Qatar AS of Denmark until June 2017 under a production sharing agreement with Qatar Petroleum, on behalf of the state of Qatar. As of June 2016, QP and the french major Total S.A. established a new company known as "North Oil Company (Qatar)". The new company is 70% owned by QP and 30% by Total. It will take over field operations from July 2017 on.HistoryThough well North West Deep-2, drilled by Shell in 1974, blew out briefly from the Shaheen reservoir, the oil field was only formally discovered in 1992 by Maersk Oil. The drilling of appraisal wells was completed in 1994 using horizontal drilling techniques. Regular oil production started the same year. In 1995–1996, production facilities were extended with subsea export pipelines, an additional single point mooring loading buoy, new process facilities and a STAR type wellhead platform.In April 2004, the extension area north of block 5 was included to the production sharing agreement. Inauguration of new offshore facilities took place on 23 February 2005.In May 2008, GSF Rig 127 operated by Transocean drilled the world record extended reach well BD-04A in the field. The well was drilled incident free to a record measured depth of 40320ft including a record horizontal reach of 35770ft in 36 days.
