...-behavior calculations. Miscibility of CO 2 and N 2 was successfully investigated through the three approaches. In the case of CO 2 , miscibility at reservoir pressure was totally ensured at 120°C since MMP was estimated to be the bubble pressure of the studied oil, more than 100 bar below reservoir...

... Depleted oil and gas fields may provide important locations for Carbon Capture and Storage (CCS). However, injection of carbon dioxide into pressure depleted oil and gas fields can be problematic due to the low reservoir pressure and the phase change behavior of carbon dioxide. The change of carbon dioxide...

The scenarios included steady-state CO 2 injection, injection shutdown, injection startup, blowout and subsequent SSSV closure, and potential leakage across the SSSV. In addition...

... injection could not improve the well performance. An additional measure to increase well productivity was to support the reservoir pressure in the northern part of the reservoir. This was implemented in late 2018 whereby, a nearby production well was converted into an injection well with a steady increase...

... by simulating multiple hydraulic fractures propagate, formation stress change and reservoir pressure rise; consequently, the stress and pressure change might make natural fractures occur tensile failure or shear failure, generating a high-conductivity zone (i.e., SRV) in the shale reservoir. To solve the model...

.... This was followed by a declining GOR period. After declining, the GOR rose and then fell off again in one of the wells. Such a behavior leaves little doubt that free gas exists. The reservoir pressure is approx. 20 bars above the bubble point, so these observations contrast with the general assumption that gas...
