A METHOD FOR RECOVERING OIL FROM AN OIL WELL

摘要

In a method for optimizing gas lift operations in the production of crude oil, a surfactant is injected into the an oil well such that the surface tension between a lift gas and the formation fluid being produced is reduced and/or a lift gas-formation fluid foam is formed. The reduction in surface tension and/or foam formation increases the efficiency of the lift gas for lifting the formation fluid to the surface. The surfactant is a silicone resin which may be combined with other surfactants, in some embodi¬ments It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.
