.... To test the feasibility of the PCP in CSS condition, we have tried the High-Temperature-Elastomer PCP (PCM198 Elastomer PCP), manufactured by PCM, in Well Shu1-39-036 after the steam injection. The result of this trial is promising, and proves that PCM 198 PCP can tolerate the high temperature in the CSS...

... to the loss of the injection agent into the BW zone, making the recovery process excessively costly. Laboratory tests of steamflooding in the presence of BW did not give very encouraging results (Chang, 1990). When considering thermal methods, there were suggestions that ISC would perform better than...

... forecasts to determine reservoir fluid flows. Generating these mental reservoir models will greatly assist in determining upside potential for oil fields. Analyzing production and injection data to formulate production forecasts and to understand oil field mechanics is a critical skill that petroleum...

... natural depletion will re-vaporize due to re-pressurization of the reservoir and by miscibility with the injected CO2. This condensate can be recovered from producing wells and leaves more pore volume for available for storage of CO2. We analyzed the injection of a CO2-based stream into a depleted gas...

The strategies included co- injection of n-hexane (C6H14) and steam, injection of C6H14 prior to steam-only injection, and injection of steam and C6H14 in alternate series of cycles. 2-D and 3-D single well and two- well simulations were preformed using the CMG STARS thermal simulator. The simulations used...

The approach consists of three steps: 1/ the construction of an initial static model, 2/ the simulation of the thermal production of heavy oil with two coupled fluid-flow and geomechanical models, 3/ the production of synthetic seismic maps at different steps of steam injection...

... Abstract In this work, a series of solvent and water injection schemes were conducted on horizontal five-spot glass micromodels which were initially saturated with the heavy oil. Sandstone and limestone rock-look-alike and network patterns, with different pores structures, were etched on glass...
