Abstract

Official abstract text for this publication.

A rock core flow test system comprises a first high pressure accumulator, a second high pressure accumulator, and a fast opening flow control device coupled to a wellbore facing end of the rock core. The fast opening flow control device opens when a pressure differential across the flow control device exceeds a predetermined threshold. The first high pressure accumulator is coupled to at least one of a pore end of the rock core and a radial surface of the rock core. The second high pressure accumulator is coupled to the fast opening flow control device. The system further comprises a pressure sensor coupled to the rock core flow test system between the fast opening flow control device and the second high pressure accumulator.
