One of the most important tools for studying fluid flow behavior in oil and gas reservoirs is reservoir simulation. It is constructed based on a comprehensive geological information. A comprehensive numerical reservoir model has tens of millions of…
The air injection process (AIP) has been widely applied to enhance crude-oil recovery. In the last decades, the limited understandings of the oxidation mechanisms complicate the prediction of the performance of AIP. The vapor-phase reaction of…
Development decisions for petroleum fields are costly and difficult because they involve long-term projects with complex systems and high level of uncertainties. Decision makers may reduce reservoir uncertainties with the acquisition of additional…
We investigate the potential for extracting heat from produced natural gas and utilizing supercritical carbon dioxide (CO2) as a working fluid for the dual purpose of enhancing gas recovery (EGR) and extracting geothermal energy (CO2-Plume Geothermal…
Reservoir simulations of the co-injection of natural gas, carbon dioxide, and other non-condensable gases into saline aquifers are in demand in many areas of subsurface utilization, ranging from excess energy and greenhouse gas storage to the…
Seepage-type gas hydrate accumulation in subsea shallow formations involves complicated thermo-hydro-solid coupling processes and matching problem between various accumulation elements. The formation physical properties control local natural gas…
Abstract For decades, oil and gas companies have been stepping up their commitment to sustainability. Unfortunately, the term “sustainability” has been politicized. By manipulating the definition of this term, today carbon—the backbone of life—has…
The evolution of human civilization is synonymous with how it meets its energy needs. A lifestyle cannot be sustained unless the energy system is sustainable. Today, an energy crisis has seized the entire globe, and the very sustainability of this…
For seepage-type hydrate reservoirs, hydrate accumulation involves natural gas supply, migration in fault/fracture channels, and hydrate generation in shallow formations under seabeds. The relationship between these three steps controls the…
Natural gas hydrate deposits hold huge potential as a future energy resource of the world including India. To help realize these resources, India carried out two dedicated research expeditions (NGHP-01 and 02) to identify, characterize and analyze…
In-situ upgrading (ISU) via downhole heating is an innovative and efficient technique for oil shale and ultra heavy oil recovery. However, low heat transfer in the ISU process can limit its application in large scale. Therefore, efficient air…
