... 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...

... process and to gain insight into the reservoir response to temperature 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...

This is done by taking the meter by meter drilling data for each offset bit run in conjunction with the offset field reported bit wear, pore pressure and lithology composition. Through different bit type inverted...

Recently, much attention has been paid to the importance of geomechanics in reservoir simulation, particularly in thermal recovery of oil sand reservoir. Deformations in an oil sand reservoir are induced by the changes of pore pressure and temperature due...

The hand pump was connected to the inlet end of the core holder, and de-ionized water was injected into the sand pack in increments until the pore pressure became equal to the overburden pressure. The injected (core pore) pressure and the injected water volume were recorded continually...
