Abstract
The present invention provides a method for encapsulating a liquid within a semi-permeable membrane. In particular, the present invention provides a method for encapsulating free flowing liquids. The current invention also provides a method for treating the downhole region of a well using encapsulated well treatment chemicals. The method of treating the downhole region of a well is particularly useful in acid etching a fracture face.
