Title Chemo-mechanical effects on rock strength, Young's modulus and poisson's ratio
Date 2010-08
Description The effect of fluids on rock strength, Young's Modulus and Poisson's Ratio is complicated and not well understood. However, many applications involving rock-fluid interactions are of considerable interest, and often pose significant physical and economic impact on a given project. Experimental measurements were carried out to assess the role of various fluids on Young's modulus, Poisson's ratio and strength of three rock types-Indiana limestone, Salt Wash South and Berea Buff sandstone. The alteration of mechanical properties as a function of fluid and exposure time was evaluated. Oven-dried, deionized water saturation, salt brine saturation, and odorless mineral spirits (OMS) saturation were assessed using unconfined compression testing. A number of triaxial compression tests at high confining pressures were also conducted. In all cases, drained conditions were maintained.
