The company said it expects recovery from the Ewing Banks 910 A-5 ST well to exceed pre-drill estimates, and the well could be online and flowing by the end of the second quarter.
The quality of the crude at Isobel Deep, Premier’s second exploration well this year off the Falklands, is similar to that at Sea Lion.
Baiyun Sag has “huge exploration potential,” CNOOC said. The area is expected to become the new reserves growth area of deepwater exploration of crude oil in South China Sea.
The discovery was made through the A1-1/1 well, which encountered gas and condensates in the Metlaoui Group of Eocene age, Eni said.
Stabroek Block is 6.6 million acres (26,800 sq km), and is about 120 miles offshore Guyana. The well found more than 295 ft (90 m) of high-quality oil-bearing sandstone reservoirs.
Tortue-1 intersected about 10 m (32 ft) of net hydrocarbon pay in the lower Albian section, interpreted to be gas. The discovery area was renamed Ahmeyim.
Well 6507/11-11 will be first well drilled in production license 591 near Heidrun and Njord fields in Norwegian North Sea. The license 591 was awarded on Feb. 4, 2011.
The license partners are currently accessing the technical and commercial implications of the discovery and looking at potential for a follow-up.
Madrid, Spain-based Repsol produces 18 Mcm of gas in Bolivia. The new gas discovery is in the Margarita-Huacaya Block in southern Bolivia, in the Caipipendi area.
During a production test, the well—constrained by surface facilities—flowed at a rate of 4,300 bbl/d of oil and 395,000 cm/d of natural gas.
This is production license 589’s first exploration well, drilled to 4,655 m vertical depth. It was terminated in Middle to Upper Triassic red sandstone layers in 262 m of water.
The gas was found at 1,307 m (4,288 ft) and well testing delivered a gas flow rate of 175 Mcm/dand 90 bbl/d of condensate with a 32/64-in. choke.
