Abstract
A laboratory test method employs maximum acoustic wave velocity to determine cure time of a sample of curable resin-coated proppant (CRCP) that are packed in a pressurized chamber to simulate conditions in a reservoir rock formation during fracturing in which the CRCP will be used. The pressurized CRCP is subjected to a varying temperature profile that replicates the reservoir temperature recovery during shut-in of the fractured zone in order to develop maximum proppant pack strength and minimize proppant flow back following completion of the fracturing operation and to determine shut-in time to complete curing of the resin.
