New subsea technology, horizontal drilling, and the existing North Sea infrastructure allowed BP Exploration Operating Co. ltd. to develop the Newsham field, a small 1967 gas discovery. Estimated originally in place recoverable reserves are 1.36 billion cu m (48 bcf). The development is in 30 m of water (98 ft) and the subsea well is tied-back to the West Sole pipeline system. The development included: converting a mudline suspension system to a subsea wellhead; deploying a horizontal subsea tree; producing gas from a subsea wellhead; deploying the subsea tree from a jack up drilling rig; installing an over-trawlable wellhead protection structure. The paper discusses field development, design, drilling, wellhead conversion, and subsea completion.
