Subsea Tiebacks: A Troll with a Kinder Surprise
less than $10/barrel, it’s indeed a low-cost project. It’s also got a low carbon footprint; the project is set to deliver about 2.2 billion barrels of oil equivalent with a CO2 intensity of 0.1 kilo per barrel.The project is Troll Phase 3, which will produce the gas cap over the Troll West oil column, in about 330 m water depth, 80 km off Bergen in the Norwegian North Sea. The NOK 7.8 billion (US$900 million) Troll Phase 3 project will extend the plateau production for gas from Troll for about seven years and the expected productive life by about 17 years. The development includes two subsea

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

production well and provide new information to help optimally plan the Lancaster field development. The Pilot Well's objectives are to: (1) confirm the depth of oil water contact (OWC) - to help refine Hurricane's estimate of Lancaster's resources by determining the height of the oil column; (2) evaluate the properties of a potential aquifer - to help refine Hurricane's estimate of recoverable oil by confirming the presence of a basement aquifer and its potential to provide pressure support to the overlying oil column; and (3) evaluate the Victory sandstone resource

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
