Paper presented at the Canadian International Petroleum Conference, June 16–18, 2009
Paper Number: PETSOC-2009-146
... Abstract The success of a stimulation technique is often measured by its stimulation ratio. This paper, however, presents a novel way of calculating the value that can be added from acid fracturing. A methodology predicting the effect of acid fracturing in carbonate reservoirs has been...

... to 1,000,000+ cP at original reservoir conditions. Current commercial thermal recovery processes used are Steam-Assisted Gravity Drainage (SAGD) and Cyclic Steam Stimulation (CSS). These methods are both energy intensive, emit significant amounts of carbon dioxide to atmosphere, and use large volumes of water...

... of steam. Energy intensity of SAGD, environmental concerns and the threat of a carbon tax make it imperative to find new oil extraction technologies. Co-injecting a hydrocarbon additive with steam offers the potential of higher oil rates and recoveries with lower energy and water consumption. A reservoir...

... Abstract In a gas miscible flooding reservoir, injection of gas, such as CO 2 , is often alternating with water to reduce the mobility contrast between gas and reservoir fluids as well as the degree of viscous fingering. Performance of a water-alternating-gas (WAG) process is largely affected...

... modalities of secondary sand fracturing can be determined. Through program calculation, the result show that compares with conventional fracturing, the fracture length and height of secondary sand fracture decrease, but the width and conductivity increase. According to real reservoir characteristics...

...) is considered, proposing to inject CO 2 separated on the platform back into the original gas reservoir. The CO 2 storage site considered is a nearly abandoned gas block in the DF1-1 gas field. Membrane separation technique will be installed on the platform for the separation. CO 2 is compressed...

... Abstract Hydraulic fracture stimulation is commonly conducted in tight gas reservoirs to improve the deliverability. The typical sequence of events during the initial completion of a tight gas well is to conduct a hydraulic fracture treatment, flow back on clean-up for 2–4 days, shut-in to run...

... Abstract The Steam-Assisted Gravity Drainage (SAGD) process has been successfully implemented to produce ultra-viscous bitumen from the Athabasca oil-sands in the Province of Alberta, Canada. In the Hangingstone area, 15 pairs of SAGD wells had been drilled by 2006 in the reservoir of maximum...

... the recovery of heavy oil reserves, such as those of Western Canada, has not been given enough attention due to immiscible nature of the mixture of CO 2 and these heavy oil resources. Many heavy oil reservoirs in Western Canada have been under waterflooding where oil is produced at very high water-oilratios...
