Mærsk Deliverer contract cancelled

Maersk Drilling has received a notice of early contract termination from Cabinda Gulf Oil Company Limited (CABGOC), Chevron Corporation’s affiliate in Angola, for the ultra-deepwater semi-submersible Mærsk Deliverer. The contract was due to end in December 2016, and as per the contract, Maersk Drilling is entitled to receive compensation for the remaining part of the contract. The contract cancellation will be financially neutral to Maersk Drilling. With regret we take note of the contract termination, and it is a reminder of the very challenging conditions in the offshore rig market with oil companies restraining activities and capital spending in response to the lower oil price environment. We expect to base the rig in West Africa, and will continue to explore opportunities with our customers in primarily West and East Africa, which remain strategic markets for us,” says Head of Global Sales, Michael Reimer Mortensen. Mærsk Deliverer has been on contract with CABGOC since May 2012. Mærsk Deliverer was built in 2009 and is designed for year-round operation in areas such as Brazil, the Gulf of Mexico, West and East Africa and Asia Pacific at water depths of up to 3,000 m (10,000 ft.).

Mærsk Deliverer back on the job

Mærsk Deliverer has successfully completed her five-yearly special periodic survey (SPS) yard stay ahead of time. The scope for the yard stay was extensive, with more than 210 job packages and 584 work orders that needed to be completed within 35 days along keyside - which makes for a very efficient and successful SPS yard stay. The scope, among others, involved Class recertification, BOP upgrade & overhaul and overhaul of the entire drilling package. Deliverer has now successfully resumed drilling operations offshore Angola. Ahead of the Mærsk Deliverer yard stay, a tremendous amount of planning and scheduling has been carried out. This was done across different departments and teams both onshore and offshore, and according to Project Manager Morten Svanholt, part of the success is due to the increased focus on teamwork. “We could not have carried out such a successful yard stay without involving the many different stakeholders from across the company. Knowledge sharing and teamwork have been essential elements in planning this project, and we will put even more emphasis on this in future projects”. CTO in Maersk Drilling, Frederik Smidth, agrees, and stresses that this achievement is no small matter to him either. “I am really proud of the team of both offshore and onshore colleagues, who have worked very hard to make this project such a success. The team has managed to complete more than 210 activities on board the Mærsk Deliverer over a very short period of time. Every minute counts in our line of business, and when we work together we can optimise the impact that these yard stays have.” says Frederik Smidth, Chief Technical Officer, Maersk Drilling. From the outset, planning has been a crucial part of the Mærsk Deliverer project and has contributed significantly to the success of the yard stay as a whole. Going forward, optimisation of the yard stay process will be a key focus area for Technical Organization and Operations in Maersk Drilling. “A yard stay equals time where the rig does not earn any money, but rather spend them instead. When we can optimise and make these yard stays more efficient, we can drive down the cost. The team has done a tremendous job in making this yard stay efficient, while still maintaining a safe environment for everyone working on the rig. That is no easy job – well done! This is a great start, but we will need to work even harder to limit the impact that yard stays have on our daily operations,” says Claus Bachmann, Asset Manager for Deepwater in Maersk Drilling.

Chevron extends 'Maersk Deliverer' contract in Angola

Cabinda Gulf Oil Company Limited, a Chevron subsidiary in Angola, has extended the current contract for the ultra deepwater semi-submersible ‘Mærsk Deliverer’ expiring in June 2015 by two years. ‘Mærsk Deliverer’ has been working for Chevron since 2012 and its partners on the Tombua Landana field offshore Angola. With the contract extension the rig will be on contract until June 2017. The estimated revenue potential from the two-year contract extension is USD 387 million plus compensation for cost escalations over the contract period. “We are very pleased to be able to extend our relationship with Chevron on this project, and look forward to a continued successful drilling operation. With its high growth potential Angola is a focus market of Maersk Drilling, and our ambition is to further build our position in this market over the coming years,” says Claus V. Hemmingsen, CEO in Maersk Drilling and member of the Executive Board in the Maersk Group.

Chariot fails to find commercial discovery at Tapir South

Chariot Oil & Gas Limited (Chariot), the Africa focused oil and gas exploration company, confirms that the Tapir South (1811/5-1) exploration well in Northern Block 1811A in the Namibe basin offshore Namibia has reached a total depth of 4,879 metres TVDss. The well was drilled by the ‘Mærsk Deliverer’ semi-submersible drillship in 2,134 metres of water and operated by Chariot’s wholly owned Namibian subsidiary, Enigma Oil & Gas (Pty) Limited. Preliminary logging results indicate that, although excellent reservoirs were penetrated, no commercial hydrocarbons were found and the well will be plugged and abandoned. The well encountered 173 metres of net reservoir sand of Cretaceous age, including two zones in excess of 30 metres with average porosities of 24% and evidence of good permeabilities. Carbonate intervals were also penetrated with porosities up to 18% over a net interval of 28 metres; these results exceeded our pre-drill estimates. Detailed analyses will be conducted on the data collected during the drilling of Tapir South. This information will be used to calibrate the existing data set and a resource update of the remaining prospectivity in the block will be provided once this evaluation has been completed.

'Maersk Deliverer' spuds Tapir South well in Namibia

Chariot Oil & Gas Limited (AIM: CHAR), the independent Africa focused oil and gas exploration company, is pleased to announce that its wholly owned subsidiary, Enigma Oil & Gas Exploration (Pty) Limited, has commenced drilling the first well, 1811/5-1, of its 4 to 5 well drilling programme offshore Namibia. Drilling operations began this morning on the Tapir South prospect using the ‘Maersk Deliverer’ semi-submersible drilling rig, with Chariot as Operator. The prospect has a 25% Chance of Success and a mean un-risked prospective resource potential of 604 million barrels of oil. In the event of success, the results of this well will significantly increase the Chance of Success on certain of the Company’s other prospects within the Tapir Trend. Tapir South (1811/5-1) will be only the second well ever to be drilled in the Namibe Basin. It is located 80km offshore Namibia in the Company’s northern block 1811A, in which Chariot has a 100% equity interest. The well is being drilled to an estimated total vertical depth subsea of 5,100m and, as announced following the Placing of 20 March 2012, this will now include extended drilling time to ensure that one of the deeper identified targets is drilled and fully evaluated. This deeper target is believed to be a carbonate section, age equivalent to the reservoir in recent sub-salt discoveries in the on-trend Kwanza basin offshore Angola. The drilling and logging operations are expected to take approximately 70 days and a further announcement will be made when the well results are known. The Tapir South prospect is part of the Tapir Trend where three prospects have been identified on a large ridge formed by a rotated fault block containing the potential carbonate target, draped by deep marine sediments with turbidite sandstone levels forming a stack of overlying targets. Tapir South is the southernmost of three culminations on the ridge and forms a focal point for charge migration from an adjacent basin in which excellent oil prone source rocks are believed to be present and currently generating oil. The second well to be drilled in the Chariot exploration programme, Kabeljou (2714/6-1), targeting the Nimrod prospect is now likely to spud earlier than previously reported. The Operator has informed Chariot that it now expects to secure a drilling unit in Q3 2012.

African Petroleum announces discovery with Narina-1 well in Liberia

African Petroleum Corporation Limited (APCL) announces that the Narina-1 well, offshore block LB-09, Liberia, has made a significant oil discovery. The discovery confirms the prospectivity of both of these highly successful West African exploration plays on APCL’s Blocks LB-08 and LB-09. Oil was found in good quality reservoirs in a Turonian submarine fan system extending across a prospective are of 250 sq km. The Narina-1 well was drilled by the ‘Maersk Deliverer’ to a total depth of 4,850 metres (15,912 feet), in a water depth of 1,143 metres (3,750 feet) taking 43 days for completion.

Narina-1 well spudded in Liberia

African Petroleum Corporation Limitied (APCL) has commenced drilling of the Narina-1 exploration well on Block LB-09, offshore Liberia where the company has a 100% interest. APCL drilled the first well (Apalis-1) in 2011 with encouraging results. The Narina-1 well will primarily target a Turonian prospect similar to discoveries like Jubilee in Ghana and Mercury/Venus in Sierra Leone. APCL estimates the targeted prospect has potential recoverable oil resources 500 mmbbls (Mean) to 1,200 mmbbls (Upside) for the Turonian reservoir plus additional potential resources in both shallower and deeper reservoirs. The Narina-1 well will be drilled by the ‘Maersk Deliverer’ semisub.

Apalis-1 well deemed non-commercial by African Petroleum

African Petroleum Corporation Limited (African Petroleum) has completed drilling the first well (Apalis-1) in deepwater offshore Liberia Block LB-09. The results of Apalis-1 confirm Blocks LB-08 and LB-09 (100% owned by African Petroleum) are located in a prospective oil basin, which is a major step forward. The geological and geophysical data have confirmed the critical components of a working hydrocarbon system are present and functioning. African Petroleum is now accelerating a multi well drilling program on the 25+ exploration prospects identified in both blocks offshore Liberia and plans to spud the next well during Q4 2011 and Q1 2012. Apalis-1 was drilled to a depth of 3,665 meters and encountered oil shows in several geological units including the shallower (Tertiary) and deeper (Cretaceous) and petrophysical analysis indicates the presence of hydrocarbons. No commercial quality reservoir with hydrocarbons was encountered and consequently no well production test was undertaken.

African Petroleum spuds Apalis-1 prospect in Liberia

African Petroleum Corporation Limited (African Petroleum) commenced drilling its first exploration well in Liberia on 8th August 2011 with the ‘Maersk Deliverer’semi-submersible deepwater drilling rig. The Company has a 100% interest in Blocks LB-08 and LB-09 and is fully funded for a further 5 additional exploration wells. African Petroleum will be drilling the Apalis Prospect on Block LB-09 in Liberia with estimated prospective recoverable oil resources of 500 (mean case) to 1,000 (upside) million barrels. Detailed technical analysis of the 3D seismic data acquired in 2010 has shown that the Apalis Prospect may contain multiple sand reservoirs in the Upper Cretaceous Maastrichtian and Turonian as well as in the Aptian and Albian. Some of the potential reservoirs in the Apalis Prospect have a well-developed 3D seismic class 3/4 AVO response, similar to those reported for nearby discoveries in Sierra Leone and Ghana. Due to the tightening rig market and limited availability of deepwater 5th generation drilling rigs in the West African region, African Petroleum has entered into agreements with Lukoil Overseas Cote d’Ivoire E&P Ltd (Lukoil), Vanco Cote d’Ivoire Ltd (Vanco) and AP Moller-Maersk (Maersk) that the ‘Maersk Deliverer’ will be released to Vanco and Lukoil for two wells after the drilling of the Apalis Prospect and will then be returned to African Petroleum for one additional well. The agreement to swap drilling slots with Lukoil and Vanco enhances the flexibility of the Company’s 2-3 well drilling program planned for 2012 as it allows the Maersk Deliverer to be reserved for the deepest water exploration drilling targets. Additionally, the planned interval between the “Apalis” well and the second well allows for the integration of both the geological and operational information to be better utilized in planning the 2012 wells. African Petroleum is currently planning to contract a second deepwater rig in 2012 to accelerate drilling plans in the West African Transform Margin.

Kora-1 exploration well drilling completion announced

Ophir Energy plc ("Ophir") announces the completion of drilling operations on the Kora-1 well in the AGC Profond Production Sharing Contract (PSC)*. Final wireline logging is now being carried out and the well will be plugged and abandoned as an unsuccessful exploration well. Kora-1 was a frontier exploration well drilled by the Maersk Deliverer semisubmersible in 2,600m of water and targeting a salt-cored, dip-closed anticline. The well was drilled to a total depth of 4447.5m subsea. Formation Evaluation While Drilling (FEWD) data shows that the primary (Albian) and secondary (Coniacian and Barremian) reservoir intervals were penetrated close to their anticipated depths, but the well encountered a predominantly claystone and thinly-bedded limestone sequence rather than the prognosed sandstone reservoir facies. In the absence of reservoir facies it is difficult to immediately assess the potential presence of hydrocarbons on the available FEWD data. A fuller analysis of the data will be required before the wider implications for the prospectivity of the Senegal-Guinea Bissau portion of the MSGBC Basin can be determined. In June 2011, Ophir completed the last of a series of farm outs on the asset. After the farm outs, Ophir's costs on the Kora-1 well have effectively been carried by the other partners. The beneficial interests in the AGC Profond PSC and the Kora-1 well are as follows:

Delivery of 'Maersk Deliverer' rig again delayed

African Petroleum (APCL) entered into a contract with Maersk Drilling in September 2010 for a two well programme using the Maersk Deliverer drilling rig. The ‘Maersk Deliverer’ is the third in a series of three state-of-the-art newbuild ultra deepwater development semi-submersibles in Maersk Drilling’s fleet and is capable of drilling in water depths of up to 3,000 metres.As mentioned in the March 2011 Quarterly Report, the Company was due to take delivery of the drilling rig in June 2011. However, Maersk Drilling has now advised that its current contractual drilling commitments with Amerada Hess Corporation for the ‘Maersk Deliverer’ rig has been extended due to that company making a discovery offshore Ghana. As a consequence, the Company now expects to take delivery of the ‘Maersk Deliverer’ in August 2011.

Delivery of 'Maersk Deliverer' delayed

African Petroleum Corporation Limited (African Petroleum) holds 100% of Blocks LB-08 and LB-09, located offshore Liberia, West Africa. Further to the Company’s announcement dated 11th March 2011 (11th March Announcement), the Company advises that due to operational delays being encountered by the existing operator, its 2011 two well deepwater offshore drilling programme in West Africa, using the ‘Maersk Deliverer’, is now expected to commence in relation to the first well in Block LB-09 in June 2011 (rather than May 2011 as previously contemplated in the 11th March Announcement).

Successful Cormoran-1 exploration well offshore Mauritania

Dana Petroleum, the operator of the Cormoran-1 exploration well in Mauritania, in which Tullow Oil plc (Tullow) is a 16.20% partner, today issued the following press release: Dana Petroleum advises that the Cormoran-1 exploration well has been drilled to a total depth of 4,695 metres below sea level and has been plugged and abandoned as a gas discovery. Stabilised gas flow rates of between 22 and 24 million standard cubic feet per day (MMscfpd) were obtained during a test of one of the four separate gas columns encountered by the well. The Cormoran-1 exploration well is located in Block 7, offshore Mauritania. It lies approximately 2km to the south of the Pelican-1 gas discovery well, which was drilled in late 2003. The well was drilled by Dana Petroleum, as Operator of Block 7, using the Maersk Deliverer deep water semi-submersible drilling rig. Water depth at the well location is approximately 1,630m. The primary purpose of the Cormoran-1 well was to test the Cormoran prospect, which adjoins but lies at a greater depth than the Pelican discovery. A secondary exploration objective was the Petronia prospect, which lies beneath the Cormoran prospect. A further objective of the well was to provide appraisal information on the Pelican gas discovery. The Cormoran-1 well encountered generally thin but good quality, gas-bearing, sands within the Pelican Group at depths between 3,376m and 3,711m true vertical depth subsea (TVDSS). This interval comprised two gas columns, one in the Upper Pelican Group (3,376 to 3,420m TVDSS) and one in the Lower Pelican Group (3,691 to 3,711m TVDSS). Good quality, gas-bearing, sands were also encountered within the Cormoran prospect, in the gross interval from 4,351 to 4,471m TVDSS, and at the top of the Petronia prospect, in the gross interval from 4,660m to 4,695m TVDSS. Drilling was stopped at a depth of 4,695m TVDSS for operational reasons (elevated pore pressures). The well was still in gas-bearing reservoir section at this depth. A drill stem test was carried out across a 33m interval in the Lower Pelican Group (3,679 to 3,712 TVDSS). Stabilised flow rates of up to 22 to 24 MMscfpd were obtained on a 32/64" choke, the flow rate being constrained by the need to avoid sand production. Substantially higher flow rates could have been achieved were it not for this operational constraint. Following the DST, the Cormoran-1 well was plugged and abandoned, this being done in such a way that the well could be re-entered in the future.

Dana begins drilling the Cormoran exploration well, offshore Mauritania

Dana Petroleum plc is pleased to report that the Dana operated Cormoran-1 exploration well has begun drilling offshore Mauritania, West Africa, just 2 kilometres southeast of Dana’s existing Pelican-1 discovery. The conductor has been run and Dana has already drilled the 26 inch hole section down to approximately 2,226 metres. The current operation is preparing to run 20 inch casing, before drilling ahead. Cormoran-1 is being drilled by the Maersk Deliverer drilling rig and is located in Block 7 offshore Mauritania. The planned total depth of the Cormoran well is approximately 4,600 metres and the well is being drilled in a water depth of 1,632 metres. Cormoran is the largest prospect in Dana’s 2010 exploration programme and, based on 3D seismic mapping, has a target reserves range of between 400 million barrels and 780 million barrels of oil equivalent. Dana holds the largest working interest in this Block 7 Production Sharing Contract area with 36%. The well is expected to encounter three discrete zones of interest between approximately 2,890 metres and 4,600 metres.

Third Deepwater Semi-submersible named

On Sunday 16 May Maersk Drilling named the latest addition to the fleet, a Deepwater Development Semi-submersible constructed at Keppel FELS in Singapore. Mrs. Merete Våge, wife of Steinar Våge, President of ConocoPhillips Norway, honoured Maersk Drilling and the yard by naming the newbuilding MÆRSK DELIVERER at a ceremony offshore Singapore. “These rigs are probably the most outstanding and complex deepwater rigs ever built. A number of innovative features have been implemented in the design, which will increase the safety of our crew and make the rigs considerably more efficient”, says Claus V. Hemmingsen, CEO of Maersk Drilling. “We are pleased that our third deepwater semi-submersible in this series is going to start up operations in West Africa, a prosperous deepwater area with much activity. The new rig is the third and final unit in a series of three highly advanced Ultra Deepwater Development Semi-submersibles. With its large capacities and highly efficient drilling equipment the new rig is capable of drilling 10,000 m (30,000 ft) into the subsoil measured from the seabed. This makes the rig particularly well suited to drill deep and technically complicated wells as seen among others offshore West Africa, Brazil, the Gulf of Mexico and Southeast Asia. The rig is able to operate in water depths up to 3,000 m (10,000 ft) and can maintain its station either in dynamic positioning (DP) mode or with a pre-laid mooring system. The initial programme for MÆRSK DELIVERER is for Dana Petroleum for drilling offshore Mauretania, West Africa. The contract has a duration of 90 days and commences upon final completion of the deepwater tests and mobilisation to Mauretania.

Third Deepwater Semi-submersible delivered

On 15 April Maersk Drilling took delivery of the third unit in a series of three identical ultra deepwater development semi-submersible drilling rigs constructed at Keppel FELS in Singapore. "The demand for modern drillings rigs has increased over the past years concurrently with the growing technical challenges we are faced with in the drilling industry. The search for new finds is moving to deeper waters and areas with complex soil conditions and more advanced drilling rigs are needed to meet those challenges. Our ultra deepwater semi-submersibles are well equipped to meet this demand”, says Claus V. Hemmingsen, CEO of Maersk Drilling. “Although the activity in the deepwater market was not unaffected by the economic slowdown in 2008 and 2009, the favourable long term oil price outlook will be supportive for exploration and development drilling in the deepwater segment, and we expect to see high demand for deepwater rigs going forward." With its large capacities and highly efficient drilling equipment the new rig is capable of drilling 10,000 m (30,000 ft) into the subsoil measured from the seabed. This makes the rig particularly well suited to drill deep and technically complicated wells as seen among others offshore West Africa, Brazil, the Gulf of Mexico and Southeast Asia. The rig is able to operate in water depths up to 3,000 m (10,000 ft) and can maintain its station either in dynamic positioning (DP) mode or with a pre-laid mooring system. As tradition bids the name of the rig will be revealed at a ceremony at the yard on Sunday 16 May 2010.
