Grieve oil field, discovered in 1954, is located in southeastern Wind River Basin, central Wyoming. This Lower Cretaceous, valley-fill and channelized, Muddy sandstone reservoir is a stratigraphic/structural trap with an average structural dip of 15 degrees. Multiple recovery mechanisms have contributed to produce more than 30 million barrels of premium light sweet crude, including gas expansio...

Condensate banking around wellbores can significantly shorten the production from gas-condensate reservoirs. Several approaches to mitigate this issue have been proposed in literature, among which gas injection comes out with promising results. This method’s efficiency has largely investigated at core and field scales, but underlying flow phenomena taking place pore-scale are still poorly under...

Carbon dioxide is a typical kind of greenhouse gases, and the oil gas field recovery ratio could be significantly improved by injecting it into formation. The main goal to increase in early stage studying injection miscible flooding. With advancement “carbon neutral” strategy China, application CO 2 flooding technology, which aims enhance Chinese oilfields, has been further expanded. developmen...

the rapid growth in natural gas consumption has increased the need for gas storage, in particular in the form of injection into depleted reservoirs. also, co2 sequestration into the depleted reservoirs has attracted a large attention recently. however, it is important to ensure that the injection pressure is maintained below a certain limit to avoid unsealing the cap rock or reactivation of any...

Pure gas permeability coefficients of a series of copolymers based on polar, hydrophilic poly(ethylene glycol) dimethacrylate, n 1⁄4 14 (PEGDMA) and siloxane-based co-monomer, [methyl bis(trimethylsiloxy) silyl] propyl glycerol methacrylate (SiGMA) are reported. SiGMA is miscible with PEGDMA and able to form homogeneous films. SiGMA contains a bulky siloxane-based end group, which acts to incre...

For the three years leading up to the end of 1995, a multi-disciplinary project team evaluated the business opportunity of injecting carbon dioxide into a portion of the Weyburn Unit to improve recovery. As with any project of this magnitude, a comprehensive analysis of the opportunities and risks in the project had to be clearly defined and evaluated. A risk assessment using a Monte Carlo simu...

For the modeling and simulation of oil recovery from naturally fractured reservoirs during the gas injection process, an accurate value of the molecular diffusion coefficient (MDC) of gases from a gas filled fracture into the oil matrix is essential. During the injection of miscible fluids with oil, transport of the injectant and oil are controlled by fracture and matrix properties. Diffusion i...

Geologic carbon storage is considered to be one of the main solutions to significantly reduce CO2 emissions to the atmosphere to mitigate climate change. CO2 injection in deep geological formations entails a twophase flow, being CO2 the non-wetting phase. One of the main concerns of geologic carbon storage is whether the overpressure induced by CO2 injection may compromise the caprock integrity...
