... the sequence boundaries until the fracture lateral location exceeds model length. Next, the well and fracture geometry are used to determine whether fractures communicate between the well and the gas cap or the aquifer. The number of trials needed for modeling various scenarios was determined using an error...

... Abstract Oil production in presence of a bottom aquifer is one of the most challenging issues in reservoir engineering. In most cases water coning happens very quickly and the influx of water restricts oil production and limits recovery. The problem is even more difficult when the oil is heavy...

In this paper, we developed a surrogate model for aquifers in the Tensleep Formation based on features of the the Tensleep reservoir at Teapot Dome in Wyoming. The corresponding oil reservoir model was history...

... Abstract In this paper, we introduce a novel technique to determine the storage capacity of a saline aquifer for CO 2 trapped because of the capillary snap-off and dissolution. The capillary snap-off trapping and dissolution into the aqueous phase are two principal mechanisms of the CO 2...

... Abstract Disposal of carbon dioxide (CO 2 ) into saline aquifers appears to be one of the best CO 2 sequestration options in terms of capacity and technology. Injected CO 2 migrates invariably upwards due to buoyancy forces. In most common aquifer settings, the density difference between CO 2...

Geologic sequestration of CO 2 has become one of the promising ways to reduce atmospheric emission of CO 2 from human activity. However, the current and future...

... Abstract Maintaining the long term storage of CO 2 is an important requirement for a large scale geologic CO 2 storage project. Nevertheless, the possibility remains that the CO 2 will leak out of the formation into overlying groundwater aquifers. There are many groundwater remediation...
