... Laboratory. These projects are: Searching for new sterically hindered animes for high capacity absorption carbon dioxide, Formulation of high carbon dioxide absorption capacity Solvents using chemical and physical absorbents, Searching for high performance random and structured packings...

... Abstract All fossil fuels form carbon dioxide when they are used There is, since carbon dioxide is a major greenhouse gas, concern that continued use may change global temperatures or, more important, change global and local climates. This paper reviews the scientific evidence for an enhanced...

... Abstract Non-thermal enhanced oil recovery (EOR) techniques show a great potential for recovering oils from the thin and shaly heavy oil reservoirs of Saskatchewan. Among the non-thermal processes, immiscible carbon dioxide injection holds the most promise of accessing these reservoirs...

... Abstract Most of Saskatchewan's light and med1um oil (LMO) reservoirs have reached economic limits of production under waterflooding 1eaving seventy to eighty percent of the initial oil-in-place (IOIP) in the reservoirs. The miscible displacement process using carbon dioxide, hydrocarbon...

... Abstract The immiscible carbon dioxide flooding process has considerable potential for the recovery of moderately viscous oils, which are unsuited for the application of thermal recovery techniques. Approximately 95% of Saskatchewan's heavy oil formations are less than 10m thick, and often...

... for using carbon dioxide and sodium hydroxide as dual additives in hot water for in-situ recovery of bitumen. The additives were introduced at a later stage of the flood following the injection of a neutral pH hot water to establish hot communications between the injection and production wells. Injection...

... Abstract A technical and economic evaluation of the applicability of the carbon dioxide immiscible process for heavy and medium oi1 recovery from Saskatchewan reservoirs has been performed. A state of the art literature review on the CO 2 -heavy oil immiscible work, which includes...

... interbeds of sand and shale with the sand lenses containing widely different amounts of smecrtite clays. To assess miscible recovery efficiencies in this complex sand, displacements tests were conducted with first contact miscible propane and carbon dioxide. Using standard waterflood relative permeabilities...

... in the province. The carbon dioxide immiscible flooding process 15 considered to be the most promising among the non-thermal recovery methods for these reservoirs. This paper presents a survey of the recent laboratory and field studies of the heavy oil-carbon dioxide immiscible process and the results obtained...
