Well 34/10-7 found oil in\r\nthe Cook and Statfjord formations and performed a drill stem test from the Cook\r\nFormation.

After production\r\ntesting DST 2 included also a seawater injection test and a seawater with\r\nsurfactant injection test. Injection rates of up to 1600 m3/day of seawater\r\nwere recorded during the final stages of the injection sequence.
