... Abstract Miscible flooding is considered unsuitable for some reservoirs in southeast Saskatchewan because of high CO, minimum miscibility pressure or operating pressure constraints. Therefore, the effectiveness of near-miscible CO 2 injection was assessedfor Steelmnn reservoir in a laboratory...

... Abstract A new approach to workovers using large-amplitude excitation of the wellbore fluid has proven successfir in establishing or restoring well productivity in Cold Heavy Oil Production (CHOP) wells in Alberta and Saskatchewan. The workover Qpically takes from five to 12 hours...

... cuttingoils; and refinery efluent (RE) from the Co-operative Oil Refinery, Regina, Saskatchewan The concentrations of oil in oily waters varied from 8.3 to 69.3mg/L. Eight-hour column studies were conducted in a 19 mm ID, 450 mm/l200 mmlong cast acrylic pipe with organo-clay/anthracite depth of 300 mm/l000 mm...

... and cumulative oil production figures. HORIZONTAL WELL HISTORY Horizontal drilling and production started in Saskatchewan in the 1950's. These early oil wells consisted of only vertical wells. This conventional method of oil recovery initially met the production needs and oil recovery percentages ofthe time...

... Abstract Three years experiences of solids disposal using Slurry Fracture Injection (SFI) are reviewed Seven separate projects in Saskatchewan and Alberta have provided an experience base in waste management using SFI. and a regulatory framework is evolving. The article addresses...

... Introduction TransGas Limited (TGL) currently owns and operates 24 salt caverns for the storage of natural gas. These storage caverns were developed in an extensive salt bed running through the province of Saskatchewan called the Prairie Evaporite, see figure 1 in the appendix. TransGas...

... Abstract Weyburn reservoir, Located in southeast Saskatchewan and operated by PanCanadian PetroLeum Ltd., has reached its economic Limit of production by waterflooding. The reservoir is a target for tertiary CO 2 miscible flooding to enhance oil recovery and extend its production Life...

.... Introduction It is the purpose of this paper to describe some of the issues facing government and industry decision makers as they develop energy and environmental policy or plan longterm projects, such as the Weyburn EaR project in South Eastern Saskatchewan, that will impact on the production, use...

... Abstract Heavy oil accumulations in A1ississipian carbonate rocks, immediately subjacentto the sub-A1esozoic unconformity in southwestern Saskatchewan, have been knownfor more than forty years. Until late 1993, sporadic attempts using verticalwells to recover oil trapped at Battle Creek have...

... Abstract As part of a larger project, the relationship of horizontal well productivity and reserves to geology and reservoir properties has been examined at the Winter and Senlac heavy oil fields in Saskatchewan and at the Pembina field in Alberta. In the Winter Cummings Sand pool, vertical...

... Abstract Thermal recovery of heavy oil has been a tantalizing prospect for Saskatchewan's heavy oil reservoirs. Over the past 30 years, many thermal methods have been tested in Lloydminster area, ranging from electrical heating and cyclic steam stimulation (CSS) in the early sixties, to tailor...

... Abstract Large volume underground storage of hydrocarbons has been developed and practiced in Saskatchewan. Canada for many years. Use of these facilities has gained importance in recent years, due mainly to economical and environmental reasons. TransGas Limited currently has 42.8 billion...

... at today's modest oil prices, there is room for profit to be made operating a CO 2 flood with flue gas extracted (,OJ. The technical and economical feasibility of the concepts are evaluated and the practical implications for the Saskatchewan resources are discussed. Introduction The concept of capturing...

... local buildings and improve local, regional and global environments. Saskoil, through its subsidiary Moose Jaw Community Energy Ltd., has proposed to construct and operate a cogen plant at Moose Jaw, Saskatchewan, to produce electricity for the SaskPower grid and heat and cooling for a district energy...

... Abstract The Rosebank olida Beds pool of southeast Saskatchewan, discovered in 1955, has produced more than 4.8 × 10 6 m 3 of light oil to December, 1990. Oil occurs in the Mississippian Alida Beds in a subcrop trap. The oil reservoir consists of the Skeletal Wackestone unit, 25 to 30 m...

... geometry variations in those intervals. Two hundred and thirty jive MICP analyses from reservoir studies in Saskatchewan make an excellent database to characterize the pore geometry a reservoir and non-reservoir rocks using R35/depth plots. The combination of these plots and detailed lithologic studies...

... Abstract There are extensive deposits of heavy oil in Saskatchewan and Alberta which can only be recovered with low efficiency by conventional methods. Primary recovery in the best of these heavy oil reservoirs can yield about 6 percent of the OOIP. Waterflooding can improve the recovery...

... 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 A waterflood prediction study has been developed for the Dodsland Viking field in Saskatchewan, Canada. This study demonstrates the importance of the geological description used to account for fieldwide variations in PVT properties. The methodology identifies the significance of local...
