If successful, the A3 appraisal well is expected to convert a portion of Liberator West's resources into reserves, in addition to determining the placement of the second Phase I production well (either L4 or L1), which would be brought onstream alongside the L2 well at a potential

Tullow Opdates on Norway Appraisal Well

West segments of the field including a production test in the Stø formation. The well was drilled approximately 5 kilometres south-west of the Wisting discovery well in the Barents Sea. Results of drilling, wireline logs and samples of reservoir fluids show that the well has encountered an oil column of 22 metres in a 1,402 metres horizontal section with 1,250 metres of net light oil pay. The main reservoir encountered was thicker than expected pre-drill. A constrained production test was carried out in the Stø Formation with a flow rate of approximately 5,000 boepd which demonstrated

Large Oil Discovery Confirmed in Brazil

the operator.   Galp Energia SGPS SA owns 14 percent, QGEP owns 10 percent and Barra owns 10 percent.   Discovered in 2012, Carcará was found to have up to 400 meters of continuous and connected oil reserves with excellent porosity and permeability. At the time it was the biggest oil column ever found in Brazil's so-called subsalt region, an area where large oil resources are trapped deep beneath the seabed by a layer of mineral salts.   The Carcará N well confirmed the size of the column discovered at Carcará and show similar porosity and permeability, suggesting

the Santos Basin, the well is approximately 4 kilometers southeast of the discovery well, the 2-ANP-2A-RJS.   The well has reached a final depth of 5,734 meters and is located 185 kilometers off the coast of Rio de Janeiro, at a water depth of 1,963 meters. The drilling results have confirmed an oil column of approximately 290 meters and a reservoir that shows good porosity and permeability. Samples collected from the well have confirmed that the oil of 27 degrees API is the same as the one found in the well 2-ANP-2A-RJS. A formation test is expected in the oil-bearing zone to verify its characteristics

Statoil: New Oil in the Grane Area

Statoil has together with PL169 partners proved new oil resources in the D-structure in the vicinity of the Grane field in the North Sea.   Well 25/8-18 S, drilled by the rig Transocean Leader, proved an oil column of 25 m in the Heimdal Formation. The estimated volume of the discovery is in the range of 30-80 million barrels of recoverable oil.   "We are pleased with having proved new oil resources in the Grane area," said May-Liss Hauknes, Statoil vice president for exploration in the North Sea. "Near-field exploration is an important part of Statoil’s exploration

and is 8 km to the southwest of discovery well (1-RJS-652A). Drilling activities have confirmed a hydrocarbon column of about 313 meters, starting at a depth of 5,166 meters, with rocks showing good porosity and permeability conditions. Besides the gas cap and condensate, the well verified an oil column of some 87 meters thick. The well drilling is still in progress and is expected to reach a final depth of approximately 5,700 meters. Samples collected from the well have confirmed similar fluids to those found in pioneer well 1-RJS-652A (Júpiter) and at both extension wells drilled

Exploration Well in Drivis Completed

made an oil and gas discovery in the Drivis prospect in the Barents Sea. This concludes the 2013/2014 exploration programme around the Johan Castberg field. Well 7220/7-3 S, drilled by the rig West Hercules, has proven a 68 metre gross gas column in the Stø formation and an 86 metre gross oil column in the Stø and Nordmela formations. Statoil estimates the total volumes in Drivis to be in the range of 44-63 million barrels of recoverable oil equivalent (o.e.), out of which 42-54 million barrels of oil. In May 2013 Statoil launched a targeted exploration campaign around the Johan
