... and permeability changes against pore pressure, and it is used to assess the pore volume and permeability variation in reservoir simulation. The pore volume and permeability variation depends not only on the pore pressure but also on stress variations. As discussed by Rodrigues (2009), coupled models may be either...

... in pore pressure. Based on the experimental results, a petrophysical model was formulated to express Vp as a function of temperature, pressure, and water saturation. The high pressure and high temperature zone of the SAGD process should generate differences between the first (2002) and second (2006) Vp...

... by CO2. First, helium as a non-adsorbing gas was flowed through core at different combinations of overburden and pore pressure at a temperature of 23°C. The pore pressure (core outlet pressure) was fist kept at atmospheric pressure and overburden pressures increased. Therefore the net stress on the core...

... and pore pressure changes. The numerical simulation is carried out using a self-developed coupled finite element model which incorporates our proposed strain-induced permeability model. The obtained simulation results were compared with the measured data. Introduction Thermal recovery processes involve...

... as a coupling parameter. The geomechanics module and the thermal reservoir simulator are used in a staggered manner. Pore pressure and temperature changes are calculated from the thermal reservoir simulator and transferred to the geomechanics module. The stress and the displacement changes are then calculated...

Through different bit type inverted ROP models the drillability or Apparent Rock Strength Log (ARSL) is predicted using an iterative process in the simulator. The converged ARSL for all the bit runs total the drilling resistance for all the different...

..., leading to closure of the cleats. At the same time, gas desorption causes coal matrix shrinkage, which leads to cleat opening. Different gases adsorb on coal to different degrees and are expected to cause different degrees of swelling or shrinkage. flow rate overburden pore pressure combination...
