Angola, officially the Republic of Angola, is a country in south-central Africa bordered by Namibia on the south, the Democratic Republic of the Congo on the north, and Zambia on the east; its west coast is on the Atlantic Ocean with Luanda as its capital city. The exclave province of Cabinda has a border with the Republic of the Congo and the Democratic Republic of the Congo.
Aker Solutions’ subsidiary Aker Oilfield Services has received a contract from Total E&P Angola for providing subsea intervention services from the oil services company’s purpose-built intervention vessel, Skandi Aker. The agreement marks a breakthrough for vessel-based intervention services in deep and ultra-deep waters.
The agreement is valid for a period of two (2) years plus options for three further one-year (1+1+1) periods. The firm two-year part of the contract has an aggregated value of approximately USD 250 million. Start-up of operations is planned to take place offshore Angola in Q1 2013.
Skandi Aker is the first well service vessel of its kind capable of performing riser-based subsea well intervention in deep and ultra-deep waters. Traditionally subsea well intervention has been performed from drilling rigs. But the rigs’ high day rates have made such operations very expensive, while rig availability has been limited. The increasing water depths also mean that it has been necessary to develop alternative technology and more cost effective systems to access deepwater wells.
“Skandi Aker is able to perform deepwater well intervention services that oil companies previously needed drilling rigs to conduct. More importantly we do it quicker and more cost effectively, which will increase the frequency of intervention operations and enable our customers’ subsea wells to produce more oil and gas,” says Karl Erik Kjelstad, president of Aker Oilfield Services and head of the Oilfield Services & Marine Assets (OMA) business area in Aker Solutions.
“We are thrilled with this award and to be able to deliver on our vision of developing a cost effective technology for intervention activities at deepwater subsea fields. We are humble about the trust placed in us by Total E&P Angola and their license partners, and look forward to deliver high quality services with the ultimate aim of increasing oil recovery ratios,” adds Kjelstad.
Under the contract Skandi Aker will perform subsea intervention activities related to:
– Well re-entry for testing operations
– Well re-entry for interventions using wireline, coil tubing and well stimulations
– Running/lifting subsea trees with cable or work-over riser
– Suspension or plug and abandonment of wells
Provision of the downhole well services, well test services and ROV services will be provided through separate contracts, outside Aker Solutions’ scope of services for Total E&P Angola.
“In recent years we have made significant investments in developing capabilities for vessel-based subsea intervention activities – both with regards to suitable deepwater technologies and services. We are pleased to see that these investments continue to materialise into contracts,” adds Karl Erik Kjelstad.
Aker Oilfield Services has built up significant resources for subsea intervention and subsea well intervention work. In addition to Skandi Aker, Skandi Santos has since March 2010 been operating very successfully on a 5+ year contract performing subsea intervention work offshore Brazil. Further, In April 2012 the company was awarded a long-term agreement with Statoil to provide a full range of heavy well intervention and light drilling services on the Norwegian continental shelf. The contract period is for eight years, with options for three further two-year periods (2+2+2). Work will be performed from a new build Category B well intervention rig owned and operated by Aker Oilfield Services.

French supermajor Total, operator of Block OML138, announces the start-up of production of the offshore Usan field in Nigeria, in line with the planned schedule. Usan is the second deep offshore development operated by Total in Nigeria, coming on stream less than three years after Akpo.
Discovered in 2002, the Usan field lies around 100 kilometers off the South East Nigerian coast in water depths ranging from 750 to 850 meters. The Usan development comprises a spread moored Floating Production, Storage and Offloading (FPSO) vessel designed to process 180 000 barrels per day and with a crude storage capacity of 2 million barrels. Its size of 320 meters long and 61 meters wide makes it one of the largest vessels of this type in the world. Development involves 42 wells that are connected to the FPSO by a 70 kilometers long subsea network.
Yves-Louis Darricarrère, President Exploration-Production at Total, stated on the occasion:
“I’m particularly proud to announce start-up of this major project together with the concession holder NNPC. This project demonstrates the ability of Total, a key operator of large-scale deep offshore developments in the Gulf of Guinea, to lead ambitious projects that will contribute to increase production for the Group and for the country. Total as operator has introduced a number of technological innovations, among which is a solution that drastically reduces gas flaring and thus minimizes the project’s environmental impact. The development of Usan has involved a record 60% of local content man-hours and thus has contributed to strengthening the know-how of the Nigerian industry in the area of hydrocarbon exploitation in the deep offshore.”
The Usan project has involved an unprecedented level of Nigerian local content, with over 500,000 engineering man-hours and 14 million construction and installation man-hours performed in Nigeria. FPSO construction included an offshore integration of 3,500 tons of locally fabricated structures. In addition, large-scale training and capacity building programs were put in place, raising the skills of the local workforce to the benefit of future projects.
Total’s wholly owned subsidiary Total E&P Nigeria Ltd. operates OML 138 with a 20% interest, while Nigerian National Petroleum Corporation (NNPC) is the concession holder. Total’s partners are Chevron Petroleum Nigeria Ltd. (30%), Esso E&P Nigeria (Offshore East) Ltd. (30%) and Nexen Petroleum Nigeria Ltd. (20%).

Songa Offshore, Cyprus-based offshore drilling company, today provided a fleet update for October 2011.
Songa Venus remained on location for Petronas Carigali, Malaysia through-out the period. The rig was shut down during the majority of the period and completed earlier announced repairs and testing of re-worked BOP components on December 19. The unit achieved 100% operating efficiency for the remainder of the period after re-commencing operations.
Songa Mercur completed its de-mobilization and load off from Sakhalin, Russia to Labuan Malaysia end of October and the rig has undergone extensive contractual acceptance testing and installation of third party equipment through November and December. The rig is now fully accepted and scheduled to depart for commencement of its two well program in Malaysia with Petronas Carigali.
Songa Dee continued its program for Statoil at the Gulfaks field, and the rig achieved an average operating efficiency of 99% during the period.
Songa Delta completed its scheduled SPS and rig upgrade yard stay at CCB base outside Bergen, Norway during the period. The yard stay was extended from an original 40 days to 56 days mainly due to extended work scopes and additional work related to the BOP system. The rig was then further delayed by weather and remained in sheltered waters until 6th January and is currently in process of anchoring up at location in order to re-commence the contract with Wintershall / Det Norske Oljeselskap.
Songa Trym achieved an operating efficiency of 99% during the period. The rig continues to operate for Statoil in Norway.
Songa Eclipse completed its mobilization to Angola during the period, and the rig is currently undergoing final rig contractual acceptance testing which is expected to be completed during second half of January. The rig will thereafter commence its one well plus 18 month contract with Total E&P Angola

The Azul-1 well, the first to penetrate pre-salt objectives in Angolan deepwater, was drilled in water depths of 923 meters and reached a final depth of 5,334 meters. The condition of the well prevented an assessment of flow capacity by a conventional test. This was performed as a mini-Drill Stem Test that enabled the recovery of two good quality oil samples.
The preliminary interpretation of the data indicated a potential flow capacity greater than 3,000 barrels of oil a day. Taking into account these encouraging results, Maersk Oil will further evaluate the results of this discovery and will proceed with exploration work in the block.
Sonangol E.P. is the block Concessionaire. Maersk Oil is operator of Block 23 with a 50% working interest with partners Svenska (30%) and Sonangol P & P (20%).
“We are encouraged by the results of our first pre-salt exploration well in this region, which was also the first ever deep water well targeting pre-salt reservoirs in the Kwanza Basin. The result may be a further step towards our goal of building up a significant business in Angola,” said Lars Nydahl Jorgensen, Head of Exploration at Maersk Oil.
“There is substantial evaluation work ahead of us to determine whether the discovery is enough to invest further to get production going. This will be done by, amongst other things, state of the art reprocessing of seismic data. Fully appraising the discovery will take several years and it is far too early to guess the outcome,” Jorgensen said.
