... Technical meetings of the Petroleum Society. Theoretical developments and laboratory experiments continue to show significant improvements for the process as compared to SAGD. Experimental results have now been obtained with Athabasca crude oil as well as Cold Lake and Lloydminster type oils. In SAGP much...

... Abstract There are abundant clay occurrences in the oil sand reservoirs in the Clearwater Formation at Cold Lake. It has been suggested that hydrothermal reactions of the clay minerals may cause permeability damage during thermal recovery. To quantify such the damage, two corefloods (BCF1...

... a correspondent water wet one. When the wettability of the sand pack was not changed, the degree of emulsification is ependent on the flow rate of water, being higher at higher rates. Considering that the initial state of the Clearwater ormation in Cold Lake is water wet, and that it may have changed over to oil...

... Abstract Imperial Oil Limited is using the Cyclic Steam Stimulation (CSS) process to recover bitumen from oil sands at Cold Lake, Alberta, The clean oil sands at Cold Lake generally produce well, but some of the oil sands with imbedded clasts have poor production. This paper presents...

... readily when steam or water mist directly contacts the Cold Lake bitumen. Furthermore, careful sampling shows that emulsions are formed when dehydrated bitumen and water flow through a sandpack. The injection or dewatered bitumen into a Cold Lake core removes water from the core by emulsification. Water...

... injection operations, leading to low oil-steam ratios. This paper considers cyclic steam stimulation in particular, in the presence of high water saturation zones. The results are based upon simulation studies for Lloydminsrer and Cold Lake reservoirs. It is shown mat cyclic steam stimulation response...

... Abstract The recovery of bitumen from oil sands deposits, such as those at Cold Lake, Alberta, is ultimately dependent on the ability to inject large amounts of steam into the ground. Oilfield steam generators have been used to provide this steam for many years in heavy oil fields...

... Abstract Esso Resources Canada Limited plans to commercially produce bitumen from oil sands at Cold Lake, Alberta, through a series of 1500 M 3 /d production phases. The drilling and completion of an initial 110 directionally drilled steam stimulation wells per phase was accomplished within...

... Abstract In order to raise 80% quality steam at 15 MPa from the produced water at Cold Lake, the water muse be deoiled, desilicized and softened. In this paper we outline our efforts to deoil the produced water by lowering the pH to around 4.5. A mini pilot running on 4L/min produced water...

... Sands. In many areas, however, the over burden thickness is such that in-situ recovery techniques provide the only means of recovering bitumen. This paper describes the drilling details of a well which will be used in an in-situ recovery pilot at Cold lake. The well, Imp 78 Horizontal Leming Ex 9-6-65...
