The Scott Field, located in the UK Central North Sea, is in a mature stage of development. The Scott platform has been on production since 1993, when the Scott Field came on stream, followed in 1996 by the subsea tie-back of the Telford Field development, located to the south of Scott. By 2005 the Scott Field had produced 400X10 (super 6) boe cumulative production. However, the field was producing at water cuts approaching 90% and the previously completed 2002-2004 infill drilling campaign had not met expectations. A change in strategy was undertaken in the subsequent 2005-2007 Scott drilling campaign, which yielded positive results, adding reserves and significantly increasing platform export rates. The focus moved from peripheral targets towards the edge of the field to lower risk targets closer to existing well control. Success was also attributed to focusing on the seismic interpretation of block bounding faults in poorly imaged areas of the field, allowing identification of small fault-bound targets. The recent drilling has demonstrated that significant value can be found in small and often complex accumulations within an extensively drilled mature field.
