Suncor fails to hit at Niobe prospect

Trapoil has announced that Suncor Energy, the operator of the Niobe prospect in Norway has concluded drilling operations on the prospect. The exploration well was drilled to a depth of 5,005 feet Measured Depth Below Rotary Table ("MDRT") or 4,871 feet True Vertical Depth Sub Sea ("TVDSS") within the Late Jurassic Heather Formation and as such has fulfilled the licence obligation. The well achieved its primary target, being the Burns Sandstone Member within the late Jurassic interval. The well penetrated good quality sands although there were no signs of significant hydrocarbons. There are no plans to conduct a drill stem test and the well is to be plugged and abandoned.

Suncor spuds Niobe prospect in the UK

Trapoil (“TRAP”), an independent oil and gas exploration, appraisal and production company focused on the UK Continental Shelf ("UKCS") region of the North Sea, has announced that operations have commenced on the Niobe (Licence P.1889, Blocks 12/26b & 27) exploration prospect ("Niobe"). The well is being drilled using the ENSCO 100 jack up rig and well operations are currently anticipated to last approximately 31 days in the dry hole case. The ENSCO 100 rig left Dundee shipyard on 4th June 2015 and was under tight tow to the Niobe prospect location until the 8th June 2015. The ENSCO 100 successfully spudded the well on the 9th June 2015. Water depth at the drilling location is 181 feet. The partners in Licence P.1889 are Suncor Energy UK Limited, operator (49.5 per cent. equity interest), Norwegian Energy Company UK Limited (22.5 per cent. equity interest) and Trap Oil Limited (28 per cent. equity interest, of which 2.5 per cent. is a carried interest).

Ithaca successfully drills fourth development well on Stella field

Ithaca Energy Inc. (Ithaca) announces the successful completion of flow test operations on the fourth development well on the Stella field, with the well achieving a flow rate of 12,005 barrels of oil equivalent per day. Well 30/6a-B2Z (B2) is the fourth development well drilled on the Stella field. The well was drilled to a total measured depth subsea of 14,461 feet, with a 2,396 foot gross horizontal reservoir section completed in the Palaeocene Andrew sandstone reservoir. The well intersected high quality sands across a net reservoir interval of 1,658 feet, equating to 69% net pay. As with the previous three Stella development wells, a clean-up flow test was performed on the B2 well in order to effectively remove the drilling fluids used to complete the well. As part of the testing programme the well was flowed at various rates over approximately a 38-hour flowing period in order to obtain additional data and fluid samples from its location on the crest of the structure to assist with reservoir management planning for the field. A maximum flow test was completed during the period, with the well flowing at a rate of 12,005 boepd on a 48/64-inch choke. This rate comprised 5,901 barrels of oil per day and 36.6 million standard cubic feet per day of gas. Fluid samples show that the oil is approximately 47° API. The B2 well is currently in the process of being suspended, with operations scheduled to be completed by the end of the month. The suspension configuration is such that the well can be brought on to production without the requirement for any further well intervention activity once the “FPF-1” floating production facility is on location and hooked up. Upon completion of operations on the B2 well the ‘ENSCO 100’ will be moved approximately three kilometres to the Main Drill Centre to drill a fifth well on the field, in the Stella Ekofisk reservoir that underlies the main Stella Andrew reservoir. The Ekofisk well is targeting light oil production in a chalk formation. The characteristics of the formation mean that initial production rates are likely to be lower than those displayed by the wells in the Andrew sandstone reservoir. Completion of the fifth well, which is expected to be in early 2015, will mark the end of the planned Stella development drilling campaign. Following completion of the B2 well suspension operations, four Stella Andrew reservoir development wells will have been completed, with the combined maximum clean-up flow test results achieved by the wells being in excess of 45,000 boepd. This well production capacity significantly de-risks the initial annualised production forecast for the Greater Stella Area hub of approximately 30,000 boepd (100%), 16,000 boepd net to Ithaca.

Ithaca Energy pushes forward with Stella development drilling

Ithaca Energy Inc. (Ithaca) announces completion of flow test operations on the third development well on the Stella field, with the well achieving a flow rate of 12,492 barrels of oil equivalent per day (boepd). Well 30/6a-B1Z (B1) is the third development well drilled on the Stella field. The well was drilled to a total measured depth subsea of 16,185 feet, with a 2,147 foot gross horizontal reservoir section completed in the Palaeocene Andrew sandstone reservoir. The well intersected high quality sands across a net reservoir interval of 2,034 feet, equating to 95% net pay. This compares to 1,312 feet and 2,514 feet in Stella wells A1 and A2, respectively. As with the previous two Stella development wells, a clean-up flow test has been performed on the B1 well in order to effectively remove the drilling fluids used to complete the well and gain additional reservoir data and fluid samples. The well flowed at a maximum rate of 12,492 boepd on a 48/64-inch choke, with the full production potential of the well limited by the capacity of the well test equipment on the drilling rig. Fluid samples show that the oil is of high quality, approximately 45° API. The maximum flow rate of 12,492 boepd comprised 7,565 barrels of oil per day and 29.6 million standard cubic feet per day (MMscf/d) of gas. This compares to the results of the A1 and A2 wells that achieved maximum flow rates of 10,835 boepd and 10,442 boepd, respectively. The test results achieved on the first three Stella development wells have served to de-risk the initial annualised production forecast for the Greater Stella Area hub of approximately 30,000 boepd (100%), 16,000 boepd net to Ithaca. The B1 well is in the process of being suspended. The suspension configuration is such that the well can be brought on to production without the requirement for any further well intervention activity once the FPF-1 is on location and hooked up. Following completion of the well suspension operations the ‘ENSCO 100’ will move on to drilling of the fourth Stella development well from the same drilling centre location. It is anticipated that the well will be completed around the end of the third quarter of 2014.
