Review and comparison on Rock Poroelastic Measurement Systems

Theory of poroelasticity is used to characterize mechanical behavior of porous media.Poroelastic coefficients are more than elastic ones becauseof complexity of porous media. These coefficients are very important inmechanical behavior analysis of Porous rocks and in oil industry issues such as subsidence, compaction and reservoir calculations. So measuring them require a system that is able to control and measure the ariables of poroelasticity. There are many systems which devised by researcher to measure poroelastic coefficients. These systems are developed by the timeto become more automated and accurate. The subject of this paper is review and comparison of rock poroelastic measurement systems.Thenumber of ٢١systems are explained and compared in details from ١٩٥٣until ٢٠٠٦. All of properties such as applied stress condition, method ofmeasurement (manual or automaticity), maximum of applied stress, porefluid, displacement measuring mechanism, temperature system, accuracy,sample size and the numbers of measured Poroelastic coefficients are discussed and the results are presented in a big table.
