PDO for Oseberg Vestflanken 2 sanctioned

Return to news list

14 June 2016

The Ministry of Petroleum and Energy has sanctioned the Plan for Development and Operation (PDO) of Oseberg Vestflanken 2. Reserves projected at 110 million barrels of oil equivalent the investments are estimated at NOK 8.2 billion (2015). The Oseberg Vestflanken 2 development consists of an unmanned wellhead platform with ten well slots. In addition two existing subsea wells will be reused. All wells will be remote-controlled from Oseberg field centre. “Oseberg Vestflanken 2 is a pioneer project of great strategic importance,” says Torger Rød, Statoil’s senior vice president for project management. The project is a pilot that other operators, public authorities and the rest of Statoil’s project portfolio are already learning from. The concept is new in Norway, but has been thoroughly tested on the Danish and Dutch continental shelves. “This new concept has been required to meet the high safety standards established for installations on the Norwegian continental shelf,” Rød says. Aiming to cut investment costs throughout the engineering phase Statoil has reduced the break-even price of the project by about 30 percent thanks to reduced CAPEX and successful maturing of the resource base, thus increasing volumes. This makes the project resilient, even in a low oil price environment. The wells at Oseberg Vestflanken 2 will be drilled by the new category J rig Askepott, which is currently under construction. It is owned by the Oseberg licence. “It is gratifying that the strategies established for the procurement of Oseberg’s licence rig is now being realised through a profitable project, optimally utilising the existing infrastructure,” says Gunnar Nakken, Statoil’s senior vice president, Operations West. Helping extend the life of the Oseberg field the project is an important contribution to Statoil’s ambition of sustaining production on the NCS at the current level to 2030, and beyond. Oseberg Vestflanken 2 is the first of three planned phases for developing the remaining reserves in the Oseberg area. “Joint optimism among the Oseberg partners about the future of the Oseberg area is at the bottom of this,” Nakken concludes.

Statoil orders new rigs to extend life of Oseberg and Gullfaks fields

Statoil has awarded contracts for a pair of newbuild jackup rigs that will be built to the company’s ‘Cat-J’ specifications for operations in the Norwegian North Sea. Samsung Heavy Industries has been awarded the construction contract whilst KCA Deutag Drilling has been awarded the operator contract for the two units. The units which are believed to cost around US$650 million each will be deployed on the Gullfaks and Oseberg fields in Norway once completed with the new rigs being owned by the license of the field rather than a rig operating company or Statoil. The first of the two units is expected to begin operating in late 2016 once it has been delivered from the yard.

Dockwise to transport two Cat-J rigs for Statoil

Dockwise, a wholly-owned subsidiary of Royal Boskalis Westminster N.V. (Boskalis) was awarded several contracts in January 2014 with a combined value of approximately USD 65 million. The largest contract award was from Statoil Petroleum AS for the transportation of two very large new jack-up drilling rigs. The two Cat-J rigs will be the largest and heaviest jack-up rigs ever to be transported on a heavy marine transport vessel. Dockwise, a wholly-owned subsidiary of Royal Boskalis Westminster N.V.

The two Cat-J rigs will be the largest and heaviest jack-up rigs ever to be transported on a heavy marine transport vessel. The two rigs are on order with a South Korean yard and are scheduled to be transported to Norway between the second half 2016 and the second half 2017. Dockwise will deploy two of its largest Heavy Marine Transport vessels: the Blue Marlin and her sister vessel the new White Marlin, which will be put into service later this year. Statoil's decision to award the contract was based on several criteria. One of them was indeed the ability of Dockwise to provide two large identical Heavy Marine Transport vessels within the same timeframe. Statoil will deploy the new Cat-J rigs to contribute in production drilling on Gullfaks and Oseberg. The new rigs will be able to operate at water depths from 70 to 150 meters and drill wells down to 10,000 meters. The Cat-J rigs are tailor-made for operations in harsh environment for both surface- and subsea wells.

New rig concept to improve recovery

Statoil is preparing an invitation to tender for a new type of drilling rig for mature fields on the Norwegian continental shelf (NCS). The new rigs, known as category J, will be jack-ups designed by the industry on behalf of Statoil. Statoil will propose for licence groups to take on ownership of these rigs. In order to realise the full potential of the NCS, increasing drilling activity on mature fields is important. Lower rig rates, greater drilling efficiency and access to rigs are key factors to meet this challenge. The new rig concept is designed to meet these requirements. “The key to maintain today’s production level on the NCS towards 2020 is improved recovery from existing fields and fast and effective development of new fields. We need to drill more wells to deliver on our production ambitions,” says Øystein Arvid Håland, head of drilling and well in Statoil. The new category J rigs will be able to operate at water depths from 70 to 150 meters and drill wells down to 10,000 meters. It is a tailor-made jack-up rig for operations in harsh environment on both surface- and subsea wells in the shallow-water segments on the NCS. It will be a tool primarily for drilling and completion of production wells. “Statoil has the capacity and competence to drive technology and innovation to drill more efficiently and rejuvenate the rig fleet on the NCS. The new category J rigs will deliver wells 20% more efficient than conventional rigs. We aim to achieve reduced cost and time per well with safe and efficient operations,” says Håland. The rig design is currently being developed in collaboration with various industry players like hull designers, topside suppliers, construction yards and drilling contractors. “Statoil is continuously working to secure a rig fleet with the right capacities and capabilities to suit our needs. However, upgrade and adaptions on many of the existing rigs appear too costly for our requirements and challenges on the NCS. We are therefore taking steps to rejuvenate the rig fleet and ensure that the right rigs meet the right requirements,” says Jon Arnt Jacobsen, chief procurement officer in Statoil. “Now we follow up our industrial approach by proposing to take ownership of the rigs through licenses to improve economics further. As a long-term industrial player on the NCS, we look forward to working with suppliers who have competence in building and operating rigs to develop new and cost-effective solutions,” says Jacobsen. Statoil plans for invitation to tender for minimum two cat J rigs to be issued in July and for the contracts to be awarded in the 2nd half of 2012. The rigs are to be delivered in the 2nd half of 2015.

ALE 30,000t load-out uses unique skidding system

ALE completed the load-out of the first 30,000t CAT-J jack-up rig in July, using a unique skidding system especially designed for the project. ALE completed the load-out of the first jack-up rig for the CAT-J project at the Samsung Heavy Industries Shipyard in South Korea. The jack-up rig, which weighed more than 30,000t, was built on top of supports on a concrete track 20m from the quayside. ALE used their own unique, self-propelled skidding system and ballasting system to load-out the jack-up rig from the quay onto a floating drydock barge. 76 skid shoes, each equipped with a 650t capacity jack, were installed underneath the rig. By extending these cylinders, the load was transferred from the building supports onto the skidding system. The three-point hydraulic suspension was created in order to control and check the stability of the system during the load-out. The ALE ballast system was installed beside the internal ballast system of the floating drydock itself. This provided sufficient ballasting capacity for the tide during the load-out and was used to compensate the barge the load was transferred from the skidding system.

Statoil awarding service contracts for two Cat J rigs

Baker Hughes and Schlumberger will be awarded the contracts for integrated drilling and well services on the Cat J rigs Askepott and Askeladden. The rigs will perform work at Oseberg and the Gullfaks. Initially awarded for four years the contracts include options for two 2-year extensions. The contracts include the following: cementing and pumping, completion, drilling and completion fluids, intergrated drilling services. Schlumberger is currently delivering integrated drilling and well services at Mariner and Baker Hughes at Johan Sverdrup. They are both important suppliers for Statoil across the drilling and well disciplines. The Norwegian head offices of both companies are located in Stavanger. “Statoil aims to run safe operations, cut well costs and ensure efficient well deliveries. We look forward to working closely with these two suppliers on the licences’ own rigs. These contracts will help increase activities on the Norwegian continental shelf, ensure predictability, and create more jobs,” says Geir Tungesvik, Statoil’s senior vice president for drilling & well. Oseberg Cat J will contribute to continued development of the Oseberg area. From the autumn of 2017 the rig will drill wells for the Vestflanken 2 project. Later the rig may be used for further developing the area in the Oseberg Future Development, phases 2 and 3. The past four years the Gullfaks field has seen substantial investments and upgrading. In 2016 consent to extended field life to 2034 was granted, almost 30 years beyond the original PDO estimate, which was 2005. The Cat J rig will be essential to the continued development of the Gullfaks field. Owned by the Gullfaks and Oseberg licences the Cat J jack-up rigs are tailored to the conditions in the North Sea, where they are scheduled to be installed in the summer and autumn of 2017, respectively. The Cat J rigs are specially designed to perform efficient drilling operations on subsea development solutions in addition to conventional surface drilling from fixed platforms. The rigs have derrick, allowing 40-metre pipe joints to be put together to increase the efficiency of the operations. They feature automatic pipe handling and the opportunity to perform parallel operations – i.e. making up pipe while drilling. They will be instrumental in ensuring that the licences recover all profitable reserves, and may also be used for exploration. The introductory Askeladden drilling programme focuses on proven reserves and gas blowdown wells on one of the Gullfaks satellite fields. Askepott will primarily drill through the unmanned wellhead platform at Vestflanken 2, which is part of Oseberg.
