Use and application of permanent downhole pressure gauges in the Balmoral field and satellite structures

Abstract

Downhole gauges installed in Block 16/21 in the North Sea have given invaluable real-time data during extended well testing. These data have improved our understanding of Balmoral and Glamis well and reservoir behavior in the early stages of production. The long-term reliability of these systems has been disappointing. The authors of this paper hope that experience gained with these systems will help others considering their use or contemplating further development of downhole pressure systems.
