Abstract
Limitations on water handling capacity at Wytch Farm mean high water-cuts from horizontal wells could lead to toss of oil production. To avoid this, a pilot study has been undertaken on a single horizontal well, to investigate the potential for a water shut-off treatment and estimate the associated risk. The study has shown that a water shut-off treatment early in 1997 should be economically beneficial to the performance of the field as a whole. Conditions that would reduce the return on the treatment have been identified and can be avoided by optimising the strategy, increasing the robustness of the project.
