Equinor and partners Vår Energi and Aker BP have struck oil in production licence PL 554 in the Northern North Sea.
Equinor and partners Vår Energi and Aker BP have struck oil in production licence PL 554 in the Northern North Sea. Recoverable resources are estimated at between 1.3 and 3.6 million standard cubic metres, corresponding to 8-23 million barrels of oil equivalent. Two exploration wells on the Garantiana West prospect were drilled some 10 km north-east of the Visund field, and 120 km west of Florø. The primary target for exploration well 34/6-5 S was to prove hydrocarbons in the Cook formation from the early Jurassic period. The secondary exploration target was to examine the hydrocarbon potential in the Nansen formation from the early Jurassic/late Triassic period. Well 34/6-5 S encountered a total oil column of 86 m in the Cook formation. A 60-metre effective medium-good quality sandstone reservoir was found.
Exploration well 34/6-5 S also encountered sandstones in the Nansen formation, but the reservoir is auriferous, and the exploration target is classified as dry. Well 34/6-5 S was drilled to a vertical depth of 3952 m below sea level and completed in the Nansen formation from the late Jurassic period. Well 34/6-5 ST2 was drilled to a vertical depth of 3750 m below sea level, and completed in the upper part of the Amundsen formation.
Eni has announced a significant oil discovery on the Eban exploration prospect in CTP Block 4, offshore Ghana. Preliminary estimates place the potential of the Eban–Akoma complex between 500 and 700 Mboe in place. The Eban – 1X well is approx. 50 km off the coast. It was drilled to a water depth of 545 m, reached a total depth of 4179 m and proved a single light oil column of approx. 80 m in a thick sandstone reservoir interval of Cenomanian age with hydrocarbons encountered down to 3949 m. The new discovery has been assessed after comprehensive analysis of extensive 3D seismic datasets. The CTP Block 4 is operated by Eni (42%). Partners are Vitol (34%, GNPC (10%), Woodfields (10%), GNPC Explorco (4%).
Turkey has shared data on its Black Sea discovery with US energy majors Chevron and Exxon Mobil ahead of possible cooperation in extracting the gas. The estimated 540 billion m3 field was one of the world’s largest discoveries last year.
Turkey has discovered 135 billion m3 of additional natural gas in the southern Black Sea with the Amasra-1 well in the Sakarya gas field, raising the total discovery in the region to 540 billion m3.
ExxonMobil made a discovery at Longtail-3 in the Stabroek Block offshore Guyana. Drilling at Longtail-3 encountered 70 m of net pay, including high quality hydrocarbon-bearing reservoirs below the original Longtail-1 discovery intervals. The well is 3.5 km south of the Longtail-1 well. It was drilled in more than 1860 m of water.
