The Forties Field and the Evolution of a Reservoir Management Strategy

The Forties Field is located 180 km ENE of Aberdeen, predominantly in UK Licence Block 21/10. It was discovered in 1970, when an exploration well encountered hydrocarbons in Palaeocene sandstone within an anticlinal structure. Four appraisal wells confirmed the existence of a major oilfield, with an area of approximately 90 km2. Initial estimates of the oil-in-place were 4600 million stb, with a recovery factor of 40%.
