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

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

Resource Estimates of Industrial Minerals in Alberta Formation Waters

Abstract: Formation waters in the Alberta basin contain dissolved minerals in various concentrations. Of these, calcium (Ca), magnesium (Mg), potassium (K), lithium (Li), iodine (I) and bromine (Br) are found in places at concentrations above the corresponding regional and detailed exploration limits. Depending on resource amount and ability to pump formation waters for mineral extraction, the potential exists for the economic exploitation of these minerals from Alberta brines. Specific areas and stratigraphic intervals in Alberta with producibility potential for Ca, Mg, K, Li, I and Br were identified based on elemental concentrations above the respective exploration thresholds, minimum thickness and porosity of the host interval, and minimum rock permeability. The use of these criteria in estimating resources ensures that the respective mineral is found in potentially economic amounts and that it can be extracted from the host formation. The distributions of the various minerals are presented as maps per element, are and stratigraphic interval and are expressed as grams per m2 of land surface or t/km2. These maps can be used for exploration drilling, resource extraction and possible plant siting. Calcium, magnesium, potassium and bromine in high concentrations are found, depending on location, between 1,240 m and 2,600 m in depth in Lower Elk Point Group strata in two areas in central-eastern Alberta, and in six areas in Beaverhill Lake Group strata in southern Alberta. Resources vary between 25 and 760 kg/m2 for Ca, 2 and 136 kg/m2 for Mg. Up to 116kg/m2 for K and up to 10 kg/m2 for Br. Lithium in high concentrations is found between 2,700 m and 4,000 m depth in west-central Alberta in reefal and platform carbonates of the Woodbend and Beaverhill Lake groups. Resources vary between 0.01 and 0.57kg/m2. Iodine in concentrations above the regional exploration threshold is found in Viking and Belly River strata in localized areas in south-central Alberta, at depths varying between 650 m and 950 m. Resources vary between 0.2 and 1.8 kg/m2 Place Keywords 72e 72l 72m 73d 73e 73l 73m 74d 74e 74l 74m 82g 82h 82i 82j 82n 82o 82p 83a 83b 83c 83d 83e 83f 83g 83h 83i 83j 83k 83l 83m 83n 83o 83p 84a 84b 84c 84d 84e 84f 84g 84h 84i 84j 84k 84l 84m 84n 84o 84p alberta canada Theme Keywords industrial minerals
