... Abstract This paper addresses the use of the Spearman rank coefficient, a nonparametric statistics, to estimate lateral autocorrelation and permeability trends. This approach provides an alternative to interference tests considering only production and injection rates. The objectives...

.... The gas distribution in the oil-depleted zone is determined by steam/gas injection rate and heat loss rate. Introduction The Steam Assisted Gravity Drainage (SAGD) process 1,2 is regarded as one of the leading in-situ recovery processes for heavy oil and bitumen resources. After the success of the UTF...

... Abstract This paper focuses on the fluid communication and injection responses in the Pekisko B Pool between January 1990 and September 1997. The analysis was based on responses of producers to changes in the injection rates. The strength of oil response is measured as the correlation between...

A combination of these instability numbers results in criteria for defining the maximum injection rates for the injected front to remain stable at the different flow segments of the pattern. An equation has been developed for the front-radius...

... Abstract Non-thermal heavy oil recovery methods are important, because many heavy oilreservoirs are unsuited for thermal methods. Emulsion flooding is one of themore promising non-thermal methods. In this experimental research, the effectof injection rate was examined for a Lloydminster crude...
