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 090

Subsurface Characterization of Acid-Gas Injection Operations in the Peace River Arch Area, 2007

In the cases of acid-gas injection into deep saline aquifers (Gordondale-Belloy, Mulligan, Pouce Coupe, Rycroft and Wembley), the extent and migration of the acid-gas plume will likely be limited by dissolution, dispersion, residual gas saturation ... Show Abstract

SPE 091

Subsurface Characterization of Acid Gas Injection Operations in the Provost Area

By the end of 2004, approximately 350 kt of acid gas had been injected into deep geological formations in the Provost area.If only the natural setting is considered, including geology and flow of formation waters, the basin and local-scale ... 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

Hydrogeology and Stress Regime of the Upper Cretaceous-Tertiary Coal-Bearing Strata in Alberta

The flow of formation waters in these strata is driven by gravity (topography) and erosional rebound, and is controlled by rock absolute permeability, gas generation and capillary pressure to gas (relative permeability). The gas content of the coal ... Show Abstract
