US firm, ExxonMobil, is preparing to drill its seventh well in the Stabroek Block offshoreDemerara.
In an advertisement published in the March 25 edition of the Kaieteur News, the Maritime Administration Department (MARAD) stated that ExxonMobil affiliate Esso Exploration and Production Guyana Limited (EEPGL) will commence a drilling programme at the Liza-4 well site within the Stabroek Block of the Guyana Maritime Zone. The programme is scheduled to last for a six-month period.
The operation will utilize the following vessels: Stena Carron, M/V Fast Hauler, M/V Dante, M/V Hannah Chouest and HOS Commander.
The drill site is approximately 102 nautical miles from the coast of Guyana and covers an area of one square kilometers.
Back in May 2015, ExxonMobil announced a huge oil find in the Liza-1 well and encountered more than 295 feet (90 metres) of high-quality oil-bearing sandstone. With the second well on the block, Liza-2, the company confirmed the finding as “significant,” with a potential recoverable resource of 800 million to 1.4 billion barrels of oil equivalent.
The Liza-3 appraisal well was subsequently drilled to a total depth of 18,100 feet in 6000 feet of water on a location about 2.7 miles from the Liza-1 discovery.
The well hit around 200 feet of net pay “in the same high-quality reservoirs” as the first two Liza wells, according to ExxonMobil partner Hess, which further solidified the potential recoverable oil in the reservoir.
