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

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

Basically, there are five ways of sequestering CO2 in geological media: 1) through enhanced oil recovery (EOR), 2) storage in depleted oil and gas geological reservoirs, 3) replacement of methane by CO2 in deep coal beds (ECBMR), 4) injection into ... Show Abstract

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

Stress Regime at Acid-Gas Injection Operations in Western Canada

An evaluation of the stress regime at the acid-gas injection sites in Western Canada was performed to assess the relationship between the maximum allowed wellhead injection-pressures and the rock-fracturing thresholds.The stress regime in the ... Show Abstract

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

BUL 062

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

Evaluation of effects of deep waste injection in the Cold Lake area, Alberta

The regional and local effects of underground injection of wastewater from in situ oil sands pilot plants have been evaluated at sites in the Cold Lake area, Alberta, using projected injection rates up to the year 2015. Geochemical effects were ... Show Abstract
