pling of reservoir fluids, with particular emphasis being placed on formation<br />
testing. A method of formation testing is described in which the pressure<br />
opposite the formation being tested is suddenly reduced, and the pressure surge<br />
resulting from the fluid being released from the formation is measured. The<br />
size of the pressure surge is controlled by both the porosity and permeability<br />
around the borehole. O. V. K.<br />
