... Abstract In preparation for a new phase of development of the deep, >8000 psi depleted, high-pressure, high-temperature (HPHT) Shearwater field in the UK Central Graben of the North Sea, the existing well stock had to be prepared to enable slot availability for sidetracking operations. Here...

... years. The field is in steep decline with high water cut in water flooded areas, and extremely low pressure in compartments produced by natural depletion. A better understanding of recovery from the main flow units is essential for estimation of drainage volume, optimisation of water injection pattern...

... to a density controlled flow. This is fortunate as density varies much less than viscosity over the production life of a field. Due to the inherent non-linear nature of a production system, the pressure drop versus flow rate will vary with degree of depletion. An ICD may be optimal initially, but not when...

... (2006) and West Franklin (2007) satellites using extended reach drilling techniques and the recent drilling of an infill well in highly depleted reservoir are some of the key contributors to the success of Elgin/Franklin. The high level of technical innovation from project conception right through...

... Abstract Two main types of reservoirs are considered for geological storage of CO 2 : deep saline formations and depleted oil and gas reservoirs. The former offer very large potential capacity and a more even distribution, at the expense of high uncertainty due to the very poor characterization...

The main objective was to obtain information on fault sealing capacity and to detect possible pressure depletion...

... Abstract The estimated recoverable reserves from the Valhall field at start of production in 1982 were 250 MMSTB. Now, after twenty years on primary depletion, a total of 500 MMSTB has been produced and additional 500 MMSTB remains to be produced of the original 2.6 BSTB in place...
