METHOD OF TREATING SUBTERRANEAN FORMATIONS BY IN-SITU HYDROLYSIS OF ORGANIC ACID ESTERS |
摘要 |
An oil or gas well penetrating a subterranean formation, such as a carbonate formation, is treated with a well treatment fluid which contains an organic ester. The fluid may be an oil-in-water emulsion of the organic ester and an emulsifier or a homogeneous solution of organic ester and a water/mutual solvent solution. Acid is produced in-situ by hydrolysis of the organic ester.
