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

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

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

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

Industrial Mineral Potential of Alberta Formation Waters

Abstract: 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 water industrial mineral data base, of which only 79 show these components xceeding the detailed exploration thresholds (Ca 60 000 mg/l, Mg 9000 mg/l, K 10 000 mg/l, Br 3000 mg/l, 1 100 mg/l, Li 75 mg/l). Concentration contour maps and data-point distribution maps identified areas and aquifers for which resource estimation was ustified. Using information from well logs, drillstem tests and core analyses, areas were identified in each target aquifer which met the combined criteria of exceeding the detailed exploration threshold for element concentration as well as aquifer thickness (>10m), porosity (>5%) and permeability (>10-14 m2, 10 millidarcies). Resource estimates were made, and are compiled, for these identified reas and aquifers. The estimates are based on element concentrations and water producibility alone, and indicate only a potential to be of economic interest; no implication with respect to economic recoverability should be construed. In view of the present market conditions, and taking into account comparisons with commercial operations elsewhere in the world, it is suggested that of the element concentrations found in Alberta formation waters only that of Li may be of additional interest at this time because contents are similar to those of the major USA producer. The study recommends that industry continue to analyze formation waters for Ca, Mg, Br, I and Li in selected aquifers and areas.
