The Beatrice field is unique in the development of North Sea oilfields because production relies exclusively on artificial lift using electrical submersible pumps (ESP's). Production started in Sept. 1981 from 3 wells and oil now is produced from 12 wells, each equipped with an ESP. Pressure maintenance is provided by 5 peripheral water injectors. Wells are completed in two groups of reservoir zones-the upper and lower. The pump/packer combination is set deep, close to the pay. Two facilities for reservoir monitoring have been incorporated in the completion design: a permanent pressure and temperature gauge with continuous surface readout, and a wireline adaptor tool with bypass tubing to facilitate production logging. Average pump installation life, excluding immediate failures, has been more than 6 months. Most failures have been associated with wells where the pump intake pressure has been below bubblepoint for an extended period. In the upper zones, where pressure maintenance is satisfactory, average run duration (ARD) has been more than 9 months. By contrast, in the lower zones, which have been depleted by 1,300 psi(8963 kPa), ARD has been more than 5 months. ESP's on Beatrice give satisfactory service pumping monophasic fluids. This is the normal condition for the field when pressure is maintained by water injection. Thus, diligent reservoir monitoring and management is needed to attain production targets.
