Economic feasibility of carbon sequestration with enhanced gas recovery (CSEGR)

West Coast Regional Carbon Sequestration Partnership - Report on Geophysical Techniques for Monitoring Co2 Movement During Sequestration

“…there are 25 CO 2 injection wells, and 16 CH 4 production wells, and 8 monitoring wells placed over the central part of the gas field (Oldenburg et al, 2004) as shown in Figure 31a. The properties (density and bulk modulus) of the CO 2 are calculated assuming hydrostatic pressure and a temperature at 1,300 m of 75°C using the NIST14 code (Magee and Howley, 1994).…”

“…We have used a reservoir simulation (Oldenburg et al, 2004) where the CO 2 injection well is in the center of the field and four production CH 4 wells are at the corners about 800 m away from the injection well (Figure 31b). This is only one five-spot simulation domain;…”

Analytical solution for Joule–Thomson cooling during CO2 geo-sequestration in depleted oil and gas reservoirs

“…5-7). The scenarios considered are based on those used in the economic feasibility study for carbon sequestration with enhanced gas recovery in the Rio Vista Gas Field, Sacramento Valley, California (Oldenburg et al, 2004b). The model parameters used are given in Table 1.…”

Basic Research Needs for Geosciences: Facilitating 21st Century Energy Systems

“…Depleted oil and gas fields have some combination of water and hydrocarbons in their pore volumes. In some cases, economic gains can be achieved through enhanced oil recovery or enhanced gas recovery (Stevens 1999;Oldenburg et al 2004;Jarrell et al 2002). Substantial CO 2 -enhanced oil recovery already occurs in the US with both natural and anthropogenic CO 2 .…”
