(London) Combined production from Tullow Oil's Horne and Wren fields in the southern North Sea has exceeded 100 MMcf/d. However, due to unprecedented UK summer/winter gas price differentials, the company has decided to shut in both fields temporarily, and during summer 2007, to provide additional gas to the UK mainland during critical winter periods.

Farther north in the southern gas basin, Tullow's Schooner-10 production well came onstream recently at a stabilized rate of 22 MMcf/d. When Tullow acquired the Schooner-Ketch complex from Shell and ExxonMobil in March 2005, the fields' combined output was expected to dip below 28 MMcf/d within 12 months. Following new optimization measures, Schoner-10 will raise the complex's production capability to around 70 MMcf/d.
