Abstract
An immiscible gas, WAG injection was initiated in the Fensfjord reservoir of the Brage Field late 1994. Two injection wells initially applied cyclic injection of gas and water. The pulse length of gas injection was about three months, and the W/G ratio has been close to 1:1. Gas breakthrough was observed after three months, according to expected breakthrough time from simulation studies. The WAG injection has later been expanded to six injection wells.
