During this phase, gel strength development and the transition time from liquid to solid are important parameters for gas handling. In the solid-state, shrinkage, matrix permeability, the heat...

..., a method enabling the prediction of sand production provides much benefit for reservoirs with sandstones of weak to intermediate strengths. Rock failure in such reservoirs may be minimised by optimising the well trajectory and perforation orientation, perforation intervals, and drawdown if the in-situ...

... The rocks are tested to determine their resistance to the subjected loading force. This type of test is called the rock strength test. It can be an indirect or direct test based on the subjected loading mode on the sample of rock. The rock strength test is a destructive test where the rock sample...
