SPE 092

Subsurface Characterization of the Edmonton-Area Acid-Gas Injection Operations

Acid gas dissolved in water in the Redwater oil field, and the resulting weak acidic solution ("sour" water) is injected into the depleted Leduc Formation Redwater reef trough 47 alternating wells. If only the natural setting is considered, ... Show Abstract

SPE 093

Subsurface Characterization of the Pembina-Wabamun Acid-Gas Injection Area

Subsurface Characterization of the Pembina-Wabamun Acid-Gas Injection Area If only the natural setting is considered, including geology and flow of formation waters, the basin to local-scale hydrogeological analysis indicates that injecting acid ... Show Abstract

SPE 095

Subsurface Characterization of the Brazeau Nisku Q Pool Reservoir for Acid Gas Injection

The experience gained since the start of the first acid-gas injection operation in Canada in 1989 shows that, from an engineering point of view, acid-gas disposal is a well-established technology. The operator has met all the current requirements ... Show Abstract

Suitability of the Alberta Subsurface for Carbon Dioxide Sequestration in Geological Media

Sequestration of anthropogenic CO2 in geological media is a potential solution to the release into the atmosphere of CO2, a greenhouse gas. Basically, there are five ways of sequestering CO2 in geological media: 1) through enhanced oil recovery ... Show Abstract

Stress Regime at Acid-Gas Injection Operations in Western Canada

Regulatory agencies in Western Canada impose safe limits on the injection pressure to maintain the pressure around the injection well below the fracturing threshold of the rocks. An evaluation of the stress regime at the acid-gas injection sites in ... Show Abstract

Industrial Mineral Potential of Alberta Formation Waters

Nearly 130 000 analyses of formation waters from Alberta and adjacent areas were searched for contents of Ca, Mg, K, Br, I and Li exceeding specified regional exploration thresholds. The 5280 analyses meeting these criteria comprise the formation ... Show Abstract

Basin-Scale Geology and Hydrogeology of Coalbed-Methane Bearing Strata in Rocky Mountain Sedimentary Basins

Except for the Black Warrior basin in Alabama, all major basins in the United States where coalbed methane is produced or have producibility potential are foreland Rocky Mountain sedimentary basins. Coalbed methane producibility depends in an ... Show Abstract
