However, designing a gel treatment represents the most complicated step in the planning of water control pilots for conformance experts, especially the treatment size design. Bulk gels are probably the most widely...

... and optimizing gel treatments represents a fundamental challenge for conformance engineers due to the lack of reliable non-descriptive design approaches. Bulk gels have been proved to be effective in alleviating water production and enhancing oil recovery from mature oil fields. They improve the vertical...
