Other mature fields given priority by Petoro in 2013 include the big Heidrun and Oseberg oil producers. As with Snorre, the main effort has related to identifying new drilling targets in order to secure a better picture of the total remaining need for wells and thereby create greater confidence in the reserve base. This is fundamental for the discussion of future development.
Petoro’s commitment on Heidrun since 2010 has convinced the partnership to carry out detailed work to realise the reserve potential. The company has played a key role in the partnership’s establishment of a project intended to produce a long-term and coherent plan for continued development of the field. Petoro’s commitment has related to changes in work processes for reservoir management, identification of new well targets and measures to boost the pace of drilling. The licence is due to decide in June 2014 whether the basis exists for starting conceptual studies. Petoro will conduct its own studies to support this process.
The commitment on Johan Sverdrup in 2013 related to promoting a coherent development of the field up to a choice of concept in February 2014. This work includes independent analyses of the sub-surface. Petoro’s field development commitment has concentrated particularly on solutions which maximise long-term value creation, including a single field centre, provision for water and gas injection, many well slots, an integrated drilling facility, enhanced oil recovery (EOR) and the provision of spare space for future phases. This is in line with the company’s strategy of shaping field development for future opportunities and manifesting the potential for EOR.
Petoro has received a supplementary appropriation from its owner related to unitisation negotiations for the Johan Sverdrup discovery between PLs 265, 501 and 502. Work on this was pursued in 2013 and will continue in the direction of negotiations in 2014.
Two plans for development and operation (PDO) were approved in the SDFI portfolio in 2013, covering Oseberg Delta 2 and Fram H North respectively. The first of these is one of Statoil’s fast-track projects, which aim to reduce the time from discovery to production and the cost of small developments close to existing fields. Three of these fast-track projects where Petoro is a licensee – Skuld/Norne, Stjerne/Oseberg and Vigdis North-East/Tordis/Vigdis – came on stream during 2013. Another five are due to begin production in coming years.
