Title: Use of alkali metal silicides in post-chops oilfield recovery operations
Inventor: KRUMRINE PAUL H
IPC: E21B43/26
Filed: 2014-10-17
Abstract: Methods of stimulating enhanced oil recovery from a post-cold heavy oil production with sand ("CHOPS") oil-bearing formation are disclosed. The invention relates to a method of stimulating oil recovery from a post-cold heavy oil production with sand (CHOPS) oil-bearing formation. The method optionally flushes a wellbore in a post-CHOPS oil-bearing formation having at least one worm hole to expel water from the wellbore and near wellbore region; then injects a alkali metal silicide into the post-CHOPS oil-bearing formation via a wellbore to introduce the alkali metal silicide into at least one worm hole within the post-CHOPS oil-bearing formation. The injection step is followed by reacting the injected alkali metal silicide to stimulate oil flow within the post-CHOPS oil-bearing formation; and recovering oil from the post-CHOPS oil-bearing formation. The alkali metal silicide dispersion can also be injected into the formation in a cyclic mode of alternating injection, soak, and production periods.
