services, materials management and information management services for the whole project. Te work will be carried out by a combined team of 600 technical experts based in AMEC’s London offices. Te two new platforms are due to be installed in 2015, with production scheduled to start in 2016. BP’s £4.5b (€5.6b) capital investment will give access to 640m barrels of recoverable oil, and see up to 120,000 barrels/day at peak, extending the life of the field to 2050 (Fig. 1). “Te award of this latest phase is a mark of confidence in the future of the North Sea, in our engineering expertise, and in our ability to deliver,” said AMEC coo Neil Bruce.
Appraisal reports Te Parkmead Group has reported that the Platypus gas field appraisal well has begun drilling in the UK Southern North Sea. Te Platyplus gas field, located in Blocks 48/1a and 48/1c, lies just 18km north north west of the West Sole gas field and 15 km west south west of the Babbage gas field. Te Rotliegendes gas accumulation at Platypus was discovered in 2010 by the Dana Petroleum plc operated 48/1a-5 well, which encountered 218 vertical feet of gas bearing sands and has the potential to contain up to 180b ft3 of gas in place.
Te drilling operation is being undertaken by
Dana Petroleum as operator. Tis well will be drilled horizontally through the Rotliegendes gas reservoir to confirm deliverability and is expected to be suspended for reuse as a gas producer. Te other joint venture partners are First Oil Expro and CalEnergy Gas. “We are delighted to report that Parkmead’s
first well in the North Sea has started drilling. Te company’s oil and gas portfolio is growing rapidly, with three acquisitions made in recent
months, giving Parkmead a balanced asset base of production, development, appraisal and exploration opportunities,” said executive chairman Tom Cross. Meanwhile Wintershall says it has made an oil
discovery at its Skarfell prospect in the Norwegian North Sea.
Te wildcat well 35/9-7, on production license 418
where Wintershall is operator, found Upper Jurassic reservoir sands of ‘very good quality’ and that contain light oil with ‘a significant oil column’. Wintershall estimates the resource to range between 60m and 160m barrels of recoverable oil, although further appraisal drilling is needed to confirm this figure. Te discovery is located approximately 10 miles
southwest of the Gjoa field in the North Sea and lies between the Grosbeak discovery to the south and the Titan discovery to the north. Te primary exploration target of well 35/9-7 was to prove hydrocarbons in the Upper Jurassic reservoir rocks. “Te Skarfell discovery is another important milestone for Wintershall and adds further growth potential to our portfolio on the Norwegian continental shelf (NCS). We are confident of the quality of our projects both in exploration and development and continue to strongly pursue our ambitious targets for the northern North Sea,” said Martin Bachmann, Wintershall exploration and production director. Wintershall has a portfolio of more than 40 licenses on the NCS, which includes more than 20 operatorships. Te firm aims to raises its daily production on the Norwegian and British continental shelves from a current level of around 4000 barrels of oil equivalent/d (boepd) to 50,000 boepd by 2015. In another development, Lundin Petroleum has announced that the Johan Sverdrup appraisal well 16/2-11 located in PL501 has encountered a

thaca Energy has agreed to take over operatorship and increase its
working interest in the Carna discovery, located in the southern gas basin of the UK North Sea. Te transaction with Centrica North Sea Gas increases the company’s working interest in the Carna discovery from 16 per cent to 32 per cent. Te financial terms of the transaction remain confidential. Te Carna discovery straddles blocks 43/21b and 43/22c and lies adjacent to the producing Garrow and

Kilmar gas fields, which constitute the Tors facilities. Te discovery was made in early 2009 when a gas column in excess of 1490 feet true vertical depth (TVD) and net pay of 127 feet TVD was encountered in well 43/21b-5Z. Te well tested gas at a gross stabilised rate of 8.8m ft3

a 48/64th choke from a vertical well penetrating the Carboniferous. Ithaca has agreed to a work
programme with all of the joint venture partners to accelerate
development studies of the Carna discovery and, if appropriate, to submit a field development plan for approval to the UK Department of Energy and Climate Change before the end of this year. Following this transaction, the joint
venture partners have the following interests in the Carna discovery: Ithaca Energy (UK), operator, 32 per cent; Dyas UK, 24 per cent; Centrica, 40 per cent; EWE Energie, 4 per cent. ●
