Subsea Tiebacks: A Troll with a Kinder Surprise
;. With a breakeven of 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

volumes. Flow was unstable due to the 4.5” DST tubing * Multiple samples of oil and gas recovered to surface from wireline logs and drill stem tests * Confirmation of correlation of the principle reservoir units between SNE-1 and SNE-2 with the primary reservoirs occurring in the gas cap as predicted * 216m of continuous core taken across the entire reservoir interval with 100% recovery * Similar oil-down-to and oil–up-to depths seen in SNE-1 - 103m gross (95m in SNE-1) * Pressure, log and seismic data indicate that the hydrocarbon column contains

sands found approximately 24 km away in FAN-1. As operator, Cairn has now issued Notices of Discovery for the SNE-1 well and FAN-1 well to the Government of Senegal on behalf of the Joint Venture. Initial analysis of the SNE-1 well indicates: * 95m gross oil bearing column with a gas cap * Excellent reservoir sands with net oil pay of 36m * Oil of 32 degrees API from samples of gas, oil and water recovered to surface * Preliminary estimates of the Contingent Resource range from P90, 150 mmbbls, P50, 330 mmbbls and P10, 670 mmbbls recoverable Further
Jupiter Well Extended in Santos Basin
, is the fourth well drilled in the Jupiter area 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 (Jú
