INTERA’s Michael Hannon, PhD, Geoscientist, recently had two papers featured in the Society of Petroleum Engineers (SPE) Reservoir Evaluation & Engineering Journal. The first article entitled Fast and Accurate Core Analysis by the Full-Immersion Pressure-Pulse Decay: Part 1—Theory focuses on a numerical simulator designed to model flow through an anisotropic porous sample, demonstrating its performance and accuracy in addition to providing a first-order comparison between the speed and shape of the pressure-decay responses of the full-immersion method with those of other similar transient methods.

Dr. Hannon’s second article, Fast and Accurate Core Analysis by the Full-Immersion Pressure-Pulse Decay: Part 2—Practice and Demonstration, continues the work of presenting a novel approach for making petrophysical assessments of tight core samples. This method, the full-immersion pressure-pulse decay, involves applying a rapid increase in pressure in a chamber surrounding the entire outer surface area of a cylindrical sample, shutting the system in, and monitoring the pressure decay in the chamber as it reaches a new equilibrium. Once complete, these developments should propel this technology to fill a critical need to determine petrophysical properties (porosity and permeability) of tight rocks in a time-efficient manner and in a way that does not compromise their accuracy.
