Ranger Oil (U.K.) Ltd. has won approval for development of its 235 bcf Anglia gas field in the southern U.K. North Sea.
In the northern North Sea, Conoco U.K. Ltd is preparing to modify Ninian oil field facilities to accommodate production from two satellite fields.
Elsewhere in the U.K. North Sea, operators awarded two major pipeline contracts to boost throughput of BP Exploration's Forties liquids transportation system.
In the Norwegian North Sea, Norsk Hydro AS has begun test production from Mime oil field.
ANGLIA PLANS
Ranger will install an unmanned platform over five predrilled wells in the eastern part of Anglia field in Block 48/19b. Anglia gas will move through a spur to Conoco's Loggs pipeline system.
Cost of the first stage of Anglia development is expected to be about 50 million ($97.5 million). Production is to begin in December 1991 at 50 MMcfd.
For the first 22 months, Anglia production will be sold to Kinetica Ltd., BP Gas Marketing Ltd., and Associated Gas Supplies (Agas) for sale to the UK industrial market.
Longer term, the gas will provide feedstock for a 350,000-450,000 kw cogeneration plant at Great Yarmouth to be operated by the Ranger led Anglia Power and Gas group.
Ranger said plans for developing the western sector of Anglia field will be finalized after observing early production performance in the east. It will be timed to extend the field's production plateau. Ranger estimated western sector development at about $50 million.
Second phase of development will entail horizontal drilling, including the recently completed 48/18b-9 appraisal well, in which Ranger set a U.K. record for horizontal displacement with a 2,940 ft horizontal section.
Shareholders in Anglia field are Ranger 35.628%, Conoco Developments Ltd., 31.25%, Elf Oil and Gas Ltd. 16.46%, Amerada Hess Ltd. 12.83%, and Triton Resources (U.K.) Ltd. 3.832%.
NINIAN SATELLITES
Chevron U.K. issued a letter of intent to Foster Wheeler Wood Group for preengineering, detailed engineering, and support services for a project to prepare Ninian facilities to handle output from Lyell and Staffa fields.
Conoco plans to develop the 30 million bbl Lyell field on Block 3/2, with output peaking at 18,000 b/d by 1994.
Chevron, Conoco, and Oryx Energy Co. recently signed an agreement with other Ninian field partners to process and transport Lyell output through a spur to Sullom Voe terminal.
Chevron expects to sign a similar agreement with Lasmo plc and Ranger for Staffa field, formerly Ninian East, on Block 3/8b. Estimated reserves are 9 million bbl, and peak production of 8,000 b/d is expected by 1992.
Chevron also is negotiating with Texaco North Sea Ltd. to handle output from Strathspey oil field in Block 3/4a.
FORTIES SYSTEM PROJECTS
Amerada Hess let contract to Allseas Marine Contractors SA, Netherlands, for oil and gas pipelines in Scott field.
Allseas will use the Allseas Lorelei barge to lay 50 miles of 24 in. liquids line from Scott to the BP Forties system. Gas will move through an 8 mile, 10 in. link into Mobil North Sea's SAGE system.
BP and Total Oil Marine let a 50 million ($97.5 million) contract to European Marine Contractors for pipelines moving oil and gas from the BP operated Bruce field. Work will start next year using the Castoro Sei pipelay vessel.
Bruce liquids will move through a 149 mile, 24 in. line to the Forties system and Bruce gas through a 3.7 mile, 32 in. link to the Frigg pipeline. Total will be responsible for the gas line.
NORWEGIAN START-UP
Norsk Hydro, Oslo, started test production from Mime field in Norwegian North Sea Block 7/11.
Production from a single subsea well tied back to Phillips Petroleum Norway's Cod platform is about 3,000 b/d.
Partners in the project with Hydro 25% are Den norsk stats oljeselskap AS 50%, Saga Petroleum 10%, Mobil Norway and Norske Conoco 7.5% each.
