.... This target may be achieved sustainably with heavy oil development using various techniques like unheated-water flooding, hot water flooding, steam flooding, and cyclic steam stimulation. The objective of this study is to investigate the later technique under the local climatic conditions. SAGD steam...

... to a small spacing between wells. This paper explains the tools developed in a field with large number of wells, and describes several workflows designed to help in the technical decision-making process of a cyclic steam stimulation operation (CSS); nevertheless, a similar approach applies to steam...

... Abstract D block is a heavy oil reservoir that was first developed in 1997 with the method of Cyclic Steam Stimulation (CSS). After nearly 20 years’ development, several technical challenges have shown: the reservoir pressure decreased from 7.4MPa to 2.9MPa, and the Steam Oil Ratio (SOR...

... Abstract Cyclic steam stimulation is one of the important ways to develop heavy oil. In the past research, saturated steam and superheated steam were mainly used as injected fluids. With the advancement of technology, supercritical water cyclic steam stimulation began to receive more and more...

... Abstract The cyclic steam stimulation (CSS) and injection process is a thermal recovery process consisting of three main stages: steam injection, steam soak and production of the heated oil. Before a stimulated well is put into production, a soak period is required to allow the injected steam...

... of penetration, the need was to find the optimal casing hole size for cyclic steam stimulation, requiring smaller holes for effective steam distribution, and holes large enough for minimal velocity during the production cycle. The first step was to process the crude oil-saturated, unconsolidated sandstone cores...

... Abstract Cyclic steam stimulation (CSS) was tested in some of the wells of a Kuwaiti heavy oil field. It was observed that the produced water-oil ratio of the CSS wells was much less than the expected range of 0.5 to 1 in a first cycle and up to 2 in a second cycle. High water retention...

... Abstract Cyclic steam stimulation (CSS) and steamflood performances are strongly influenced by shaly barriers and cemented baffles in the heavy oil reservoir. Marine shales do act as a permanent barrier in most conditions, while non-marine shales and diagenetically altered cemented siltstone...

... equivalent of SAGD is not feasible as an economic recovery process. Cyclic steam stimulation (CSS) and steam-assisted gravity drainage (SAGD) are now over two decades old since invention and at this point there are few new technologies on the table which are being researched or evaluated. Most new...
