Abstract
Organoclay is used as an alternative emulsifier and reinforcing agent to enhance the strength of emulsified polymeric gel aqueous solutions and form water in oil emulsions. The stability of the emulsion can be controlled by controlling salinity and the intensity of initial mixing. The new system can be used for water shut-off treatments as well as a relative permeability modifier in high water permeability zones. In addition, the system can tolerate salts much better than classical surfactants. This system will be appropriate for wellbores having high temperature (>85° C.) with harsh environmental conditions.
