Paper Number: ISRM-ISRS-2016-008
... in limestone formations observed above soft argillite layers encountered in this region. Further, the pore pressure measured in the argillite is larger than that measured in the surrounding permeable zones. These observations suggest a presently active source of stress in this sedimentary system. We propose...

... Abstract We compared the simulation results given by 3-D and 2-D models using finite element method, which indicates that 3-D computation is more close to theory result. To calculate different factors act on the elastic stress and pore pressure separately, the results show that poorly...

... slotting. It is important for the development of low-permeability oil field. 2 MECHANISM OF SLOTTED WELLS TO INCREASE PRODUCTION The rock of the effective stress formula is where ij = effective stress; ij = stress in the rock; ij = function; p = pore pressure; and = equivalent pore compressibility...

... ABSTRACT: According to the relationship of the percolation ability and the pore pressure of coal reservoir, an interpretation method of analyzing the pressure attenuation testing data is derived by use of the Duhamel principle. Consequently, the pore pressure of coal reservoir is obtained...
