Abstract
The acid emulsion for acid treatment of oil reservoirs is an emulsion for the acid treatment of the rock reservoir around oil well bores. The acid emulsion includes an oil, such as kerosene, and an emulsifier added to the volume of oil to form an oil-emulsifier mixture. The emulsifier forms about 0.1 wt % of the oil-emulsifier mixture, and is preferably an organically modified montmorillonite clay. Brine is added to the oil-emulsifier mixture to form the acid emulsion. Preferably, the brine has a salt concentration of about 20 kppm, and is added such that the volume ratio of the brine to the oil is about 70 to 30.
