The Brent field, 116 miles northeast of Lerwick, Shetlands Islands had 3.8 billion STB oil originally in place and 7.5 Tcf gas originally in place. The field was discovered in July 1971 and brought on production 5 years later, on 11 November 1976. The field reached a maximum annual average oil production of 410,000 B/D in 1984. Since the mid-1980`s, oil production has been declining, but substantial gas reserves remain dissolved in the residual and bypassed oil because of the high solution-gas/oil ratio. Since the outset of field development, ideas have been conceived to recover these large gas volumes and to optimize oil recovery further. As oil production started to decline, a wide range of improved- and enhanced-oil-recovery (EOR) options were systematically evaluated. The full-length paper presents details of the depressurization plan, early results, and a number of related issues and how they are being managed with references to several papers that describe these issues in greater detail.
