Core Lab operates a full service geomechanics laboratory that provides customers with test data
and engineering analyses to predict borehole failure. Wellbore stability and sanding predictions
are simulated in the laboratory by performing either traditional thick-wall cylinder test or our
proprietary advanced thick-wall cylinder test.
Traditional Thick Wall Cylinder Test
Lab Simulation of Perforation Failure
The thick-wall cylinder test employs a geometry that simulates actual loading conditions under
downhole stresses. This provides direct measure of pressures under which a hole will start producing
sand or cause other problems like casing collapse. Armed with this information, an operator can control
conditions to maintain wellbore stability.
