... on the injection rate. These phenomena are dependent primarily on the difference between the injection and reservoir temperature. An optimization algorithm for injection temperature is discussed based on limiting the maximum fracture length and minimizing the risk of leakage from thermal effects of CO 2 storage...

... wells, increasing the injection rate for a CO 2 well does not necessarily increase its wellhead operating pressure. A methodology to estimate wellhead operating pressures is a key requirement for the proper design of the injection wells and the CO 2 surface facilities. It may also help engineering...

... in a sandstone at 1900 ft. The injection rate was 20-25 tons/day. A water injection well was converted to a CO 2 injection well. The well is centrally located between eight oil producing wells. CO 2 injection ended in May 2010 with cumulative injection of about 7,200 tons. Twelve months of water injection...

... Abstract Commercial CO 2 geologic storage will require large injection rates and will favor pipeline transport of CO 2 as a dense (liquid) phase. Thus the temperature of CO 2 entering a storage formation may be significantly lower than the formation temperature. This difference...

... samples with viscosities of 1000 to 2000 cp were used and experiments were carried out at pressures of 500 and 1000 psi (3.45 and 6.9 MPa), temperature of 30°C, and water injection rates between 1 and 50 feet per day. Carbonated water used in these experiments was prepared by dissolving CO 2 in brine (1...

.... The impacts of various parameters were broadly studied on the recovery efficiency and gas multiphase flow at pore scale. These were pressure, temperature, composition, injection-rate, and permeability heterogeneity. Results indicated that the recovery factor at CO 2 breakthrough is a function of in situ gas...
