What is Chemoporoelastic Analysis and Experimental Validation of the Pore Pressure Transmission Test for Reactive Shales about?
This paper analyzes the pore pressure transmission test within the framework of the Biot theory of poroelasticity, extended to include physicochemical interactions. The main outcome of this laboratory experiment, which is aimed at quantifying the osmotic properties of a chemically sensitive shale in contact with a water-based fluid, is the membrane efficiency. On the basis of a mathematical model of the test, we show that under certain conditions there is equivalence between the membrane efficiency and the reflection coefficient R, a transport parameter that quantifies the departure of the shale from an ideal osmotic membrane. Under these conditions, which hinge on the existence of an intermediate time asymptotic solution linked to a separation of time scales, the membrane efficiency is virtually independent of the specific experimental setup. We also report the results of several pore pressure transmission tests on Pierre II shale, as well as the identification of some chemoporoelastic parameters from these experiments.
