30 December 2015

It is with great sadness that Statoil and COSL have received confirmed information from the police that one person has died as a result of the breaking wave that hit the drilling rig COSL Innovator today. Two other people were injured and are receiving medical treatment ashore. The rig is now heading to shore under its own power, while evacuation takes place. COSL and Statoil were notified at 5 pm on Wednesday 30 December that three people had been injured when a breaking wave hit COSL Innovator. Statoil and COSL have mobilized their emergency response organizations. COSL Innovator is under contract to Statoil at the Troll field in the North Sea, west of Bergen. The rig had been taken off the well as a result of the bad weather before the incident occurred. The breaking wave also caused some damage to the rig's accommodation module. The injured persons have been flown to shore by Sea King helicopter from the Joint Rescue Coordination Centre and by one of Statoil’s own rescue helicopters. Statoil is assisting COSL with evacuation of the rig down to the safety crew. Evacuees are being flown ashore.

Statoil to use 'COSLInnovator' for Troll production drilling

Statoil Petroleum AS (Statoil) has received consent from the PSA to use the ‘COSLInnovator’ mobile drilling facility for production drilling on the Troll field using the Controlled Mud Level method. The consent covers the use of ‘COSLInnovator’ for production drilling on 8½" sections in well 31/2-L-22 on the Troll field using the Controlled Mud Level method. Statoil received consent to use ‘COSLInnovator’ for production drilling at Troll in June 2012. The consent will now be extended to cover use of the Controlled Mud Level method. Controlled Mud Level (also called Dual Gradient Drilling – DGD) is a new technology, which Statoil has tested as a pilot project in another production well at Troll. The company now wishes to perform a new pilot study in order to implement improvements and experiences from the first pilot, before widespread deployment of the technology. According to Statoil's application for consent, in time the Controlled Mud Level method will allow wells to be drilled in depleted reservoirs when it is no longer possible to drill using conventional methods.

'COSLPioneer' contract to be temporarily suspended

Due to overcapacity in our rig portfolio, Statoil will lay up the ‘COSLPioneer’ rig in the fourth quarter of 2014. The rig is currently carrying out an assignment on the Visund field and is scheduled to complete this work at the end of September. “After a careful review of our drilling plan, we find it necessary to suspend ‘COSLPioneer’ for the time being,” says rig procurement responsible Tore Aarreberg. In the beginning of July Statoil also announced that the drilling rig ‘Scarabeo 5’ will be temporarily suspended. ‘Scarabeo 5’ will be taken out of operations at the end of September for the rest of the year. “At the moment we have three rigs contracted from COSL Drilling Europe. Our offshore organisation enjoys excellent cooperation with the contractor’s drilling teams, and COSL Pioneer has demonstrated consistent, high efficiency in drilling operations. We are in close dialogue with the contractor concerning how the suspension of the rig will be implemented in practice, and we continue to look forward to many years of cooperation with COSL on the Norwegian shelf,” Aarreberg says. The rig is contracted until 2016 and will be used for drilling and completion of production wells on the Norwegian continental shelf. ‘COSLPioneer’ being taken out of operation for a shorter period will have no impact on Statoil’s production targets or planned exploration activity on the Norwegian shelf. The company will still be drilling 20-25 exploration wells on the Norwegian shelf in 2014, where the company operates about two-thirds of all wells.

CalEnergy's Pryderi-1 well comes up dry

IPB Petroleum advises that the Pryderi-1 exploration well in WA-424-P (IPB 75%, CalEnergy 25% and Operator) reached a total depth of 694m (RT) in 12.25” hole late afternoon on 15 November 2014 with no moveable hydrocarbons being encountered. Despite some residual oil shows encountered while drilling, the target reservoir at Pryderi is interpreted to be water bearing. Operations over the next 48 hours include the planned plugging and abandoning of the well. IPB now intends to complete further interpretation and analysis on the results of the well to gain an improved understanding of the remaining prospectivity within the permit, which includes the existing Gwydion oil discovery (2C Contingent Resources of 5 MMbbls -100%). IPB’s Managing Director Brendan Brown said “Although the results of this first well are not as predicted, we know that oil is present in this part of the Browse Basin and the data from this well will help us in our ongoing exploration efforts within the permit. IPB remains confident that the company’s existing acreage offers significant hydrocarbon prospectivity in a basin that is a focal point for so many multinational energy companies.” IPB would like to reassure shareholders that the evolution of successful small exploration companies often involves dealing with exploration risk outcomes and pursuing multiple options. The directors aim to also continue with their stated strategy which includes the examination of complementary opportunities, with the ultimate objective of adding to the company’s current exploration portfolio.

Statoil announces extension of suspended rig contracts

Due to continued overcapacity in its rig portfolio, Statoil has extended the suspension periods for COSL Pioneer, Scarabeo 5 and Songa Trym. The suspensions are also a result of the failed attempts to mature alternative tasks for the rigs. “When the rig contracts were signed it was challenging to ensure sufficient rig capacity. Today the activity is facing lower margins, a generally high cost level and subsequent lower profitability. It is therefore more demanding to mature profitable drilling targets,” says Statoil procurement head Jon Arnt Jacobsen. COSL Pioneer, Scarabeo 5 and Songa Trym were initially suspended until the end of the year from 8th October, 5th October and 20th November, respectively. COSL Pioneer will be suspended for an additional seven and a half months. The suspension periods for Scarabeo 5 and Songa Trym will be extended by one and a half months and one month, respectively. The extension period for Songa Trym may be reduced, or avoided, if acceleration of activities is achieved. “I would like to emphasise that the suspensions are not related to the rig deliveries. We are very pleased with the work they have done for us. These measures are necessary due to the overcapacity of rigs compared to the assignments we are prioritising. This situation is unfortunate, and we are doing what we can to minimise the extent of the suspensions,” Jacobsen says.

Primeline Completes LS23-1-1 Well and Will Continue with Drilling of LS30-3-1 Well

Primeline Energy Holdings Inc. (“Primeline” or the “Company”) (TSXV: PEH) today announces that it has completed the drilling operations of the LS23-1-1 well and will now continue with the exploration drilling programme for the LS30-3-1 well. The LS23-1-1 well was spudded on September 23 and reached total depth (TD) of 2,666m on October 21, 2015 and wireline logging data was subsequently acquired. The well encountered sandstone units of Paleocene and early Cretaceous age, drilling through the geological sequence as anticipated and finished in basement rock. It discovered several zones of gas bearing sandstone and evaluation of logging data indicated total cumulative net pay thickness of 14 metres. The LS23-1 prospect is a technical discovery of hydrocarbon but not likely to be a commercial discovery. Therefore Primeline has plugged and abandoned the well and will proceed with the drilling of the LS30-3-1 well on the basis of the agreed two well work programme. LS30-3-1 is located approximately 20km north of the LS36-1 gasfield platform and is targeting a large channel sand prospect. The prospect was originally mapped in 2009/2010 and refined during the 2014/2015 evaluation. The planned TD of the well is 1,800m, targeting the same reservoir as that of the LS36-1 gasfield. The drilling rig HYSY941 is currently conducting the final operations for the LS23-1-1 well. Once completed, Primeline’s contractor China Oilfield Service Ltd plans to mobilise the rig to the LS30-3-1 location subject to weather and sea conditions, allowance for necessary equipment maintenance and preparation and approval of the operation licence. A separate announcement will be made when the drilling operation of LS30-3-1 commences.

Primeline Completes LS30-3-1 Well

Primeline Energy Holdings Inc. (“Primeline” or the “Company”) (TSXV: PEH) today announced that drilling operations of the LS30-3-1 well have been completed without discovering hydrocarbons LS30-3-1 is located approximately 20km north of the LS36-1 gas field platform and was targeting a large channel sand prospect as part of Primeline’s two well exploration drilling programme for 2015. The well spudded on November 13. When the well reached the planned total depth of 1800m, Primeline decided to deepen the well, drilling to a total depth of 2000m on November 27 with electronic log data being collected during November 27-30. The analysis of the results shows that whilst the well encountered three sets of very good sandstone reservoir sequences as predicted, unfortunately there was no oil or gas accumulation in those sandstones. The LS30-3-1 has thus been declared as a dry well and the plug and abandon operation is now ongoing before the rig is released. Primeline will conduct a careful post well evaluation of the results of the LS23-1-1 and LS30-3-1 wells in the coming months in order to formulate the next stage of the exploration programme in the remainder of the 5,877sq km of Block 33/07.

COSL Completed a High-quality Workover Integrated Operation with a Semi-submersible Rig

China Oilfield Services Limited (“COSL” or the “Company”), has smoothly completed its first workover integrated operation with a semi-submersible rig, NH5 of the Company, in South China Sea waters. There were huge challenges for this workover operation stemming from the swinging trunk of the semi-submersible rig due to the winter monsoon in South China Sea. Guided by excellent environmental protection concepts, NH5 developed appropriate measures and cooperated closely with the partners and tackled difficulties in precision positioning of the equipment and seamless matching of the operation procedures. NH5 completed this workover operation smoothly, thereby established a solid foundation for the timely resumption of production of the well for the client. With this outstanding operation, NH5 has not only helped COSL generate revenue, but also won full recognition and endorsement with relevant praise from the client.

Statoil terminating rig contract

Statoil has, on behalf of the Troll licence, decided to use its contractual right to terminate the contract with COSL Offshore Management AS for the chartering of the mobile rig COSLInnovator. “The conditions for terminating the contract signed with COSL Offshore Management AS have in our opinion been met, and we therefore choose to use our contractual right to terminate the contract,” says Geir Tungesvik, Statoil’s senior vice president for drilling and well. In addition Statoil has decided to stop drilling operation with the sister rig COSLPromoter when it is safe to discontinue well operations. This is done in order to enable COSL to implement the necessary actions in order to fulfil the requirements of the contract. The decision may have some short-term consequences for planned drilling activities, but will not have impacts on long-term production on the Troll field. The plans made by the licence for gas and fluid production from the oil zone remain firm.

Statoil makes gas discovery near Visund field in Norway

Statoil Petroleum AS, operator of production licence 120, has concluded the drilling of wildcat well 34/8-17 S. The well was drilled on the northeast flank of the Visund field, in the northern part of the North Sea. The well's primary exploration target was to prove petroleum on the east flank of the Visund field in Lower Jurassic reservoir rocks (the Statfjord group). The secondary exploration target was to prove petroleum in Lower Jurassic (Lower Statfjord group) and Upper Triassic reservoir rocks (the Lunde formation). The well encountered an approx. 31-metre gross gas column in the Tarbert, Ness and Etive formations in the Middle Jurassic, about 20 metres of which were in sandstones with very good reservoir quality. In the immediately underlying reservoir rocks in the Rannoch formation in the Middle Jurassic, the well encountered an approx. 21-metre petroleum column in sandstones with poor reservoir quality. Traces of petroleum were also encountered in Lower Jurassic sandstones of variable reservoir quality in the Cook formation and in the Statfjord Group. It is unclear at this time whether there is oil or gas in the Rannoch and Cook formations, and in the Statfjord group. The Lunde formation is aquiferous. Data acquisition and sampling were conducted in the well, but it was not formation-tested. Preliminary estimates place the size of the discovery at between 0.5 and 2 million Sm³ recoverable oil equivalents. The licensees in production licence 120 will consider tying this discovery to existing infrastructure in the Visund area. This is the 24th exploration well in production licence 120, which was awarded in the 10th licensing round, part A, in 1985. 34/8-17 S was drilled to a vertical depth of 3187 metres below the sea surface, and was terminated in the Lunde formation in the Upper Triassic. The water depth is 378 metres. The well will now be permanently plugged and abandoned. Well 34/8-17 S was drilled by the COSL Pioneer drilling facility, which will now drill a sidetrack to a production target in the Visund field.

Small oil discovery in the Oseberg Area Unit

Statoil, together with partners in the Oseberg Area Unit, has made a small oil discovery in the production license PL053 in the North Sea. Statoil and its partners are in the process of concluding drilling operations in the exploration well 30/6-28S located in the production license PL053 in the Oseberg Area Unit. The well drilled by the rig COSL Pioneer proved an oil column of 12 metres in the Statfjord Formation. The estimated volume of the discovery is in the range of 12-18 million barrels of recoverable oil equivalents. "The oil discovery is located beneath the Oseberg field and is a good candidate to be connected to the Oseberg production facilities. These could be fast and high-value barrels for the partnership," says Knut Henrik Dalland, vice president Operations Oseberg. The oil discovery lies in the Crimp prospect, which was the secondary target for the exploration well 30/6-28S. The primary target was the Crux prospect that Statoil earlier defined as a high impact gas opportunity. With the Crux prospect Statoil tested a hypothesis for the existence of a separate gas-filled structure underlying the Oseberg field. However, the Crux prospect did not contain hydrocarbons. "The well 30/6-28S had two objectives. First, to test a new play in the area – the Crux prospect, which was a high risk / high reward opportunity. Second, to test an infrastructure-near prospect called Crimp, with relatively modest volumes but attractive economics. Unfortunately, we have not found gas in the Crux prospect, but we are pleased with the oil discovery in Crimp. Even though our high impact opportunity has not materialised, we have delivered some valuable additional resources to the Oseberg Unit," says Tore Løseth, vice president Exploration Licenses North Sea. After completion of the exploration well 30/6-28S, the COSL Pioneer drilling rig will move to the Glitne field. Exploration well 30/6-28S is situated in the production license PL053 in the Oseberg Area Unit in the North Sea. Statoil is the operator and has a 49.3 % interest. The partners are Petoro AS (33.6 %), Total E&P Norge AS (10.0 %), ExxonMobil E&P Norway AS (4.7 %) and ConocoPhillips Skandinavia AS (2.4 %).

Another discovery in the Gullfaks area

Statoil’s drilling of the Skinfaks South well in the North Sea has been completed and the estimated volume is between 1.9 and 6.9 million barrels of oil equivalents. This is the fourth infrastructure-near discovery in the Gullfaks area in a 10 month period. Light oil has been confirmed in Middle Jurassic reservoir rocks (Brent group) and a 80 metre high column in good-quality reservoir rocks. "We are currently evaluating how this discovery can be connected to the existing infra-structure," says Tore Løseth, exploration vice president for North Sea. Skinfaks South is located directly west of the Gullfaks field in the North Sea Tampen area, where Statoil is focusing on infrastructure-led exploration (ILX). "Our exploration strategy for the Norwegian continental shelf focuses both on high-impact discoveries and what we call time-critical ILX, which is exploration close to installations that within a couple of years will have the capacity to receive the oil and gas we find," Tore Løseth says. Gullfaks is a good example of how an area has developed after its first major discovery. Discovered in 1978 the Gullfaks field contained an estimated 2.5 billion barrels of oil equivalent. The discovery of fields such as Gullfaks South, Rimfaks and Valemon has later added another billion barrels of oil equivalent to the area. Statoil has continued its exploration activities around Gullfaks, and in one year four new discoveries have been made: Rutil, Opal, Brent 10 A/B and now Skinfaks South. They will add a total of 50-100 million barrels of oil equivalents. In 2012, 40% of Statoil's exploration wells on the Norwegian continental shelf will be ILX wells. ILX drilling is to be carried out close to Oseberg, Snorre and Norne.

Brugdan II well temporarily suspended

Statoil and its partners ExxonMobil and Atlantic Petroleum have decided to temporarily suspend operations on the Brugdan II well offshore the Faroe Islands. The Brugdan II well has drilled into the sub-basalt section, but the primary objective has not yet been reached. The decision to suspend the drilling is based on the expected bad weather as we enter the winter season. The Faroese authorities have authorised a suspension until end 2013. The well is located around 80 km offshore from the Faroe Islands and was spud in June 2012. It has been drilled with the COSL Pioneer semi-submersible rig in a water depth of around 450 meters. The Brugdan II well is the second exploration well that has been drilled in licence 006 which covers an area of approximately 579 square kilometres. Statoil has been in the Faroe Islands since 2000 and holds a significant acreage position with 6 operated licences. The licences are all sub-basalt and have a varied geology within different plays. The position in the Faroe Islands is in line with the company's exploration strategy of early access of scale and establishing a leading position in frontier areas. Statoil Færøyene AS has 50% equity in the Brugdan licence. The partners are partners ExxonMobil Exploration and Production Faroe Islands Ltd 49% and Atlantic Petroleum P/F 1%. The Brugdan II well is the 8th exploration well drilled in Faroese waters since 2001.
