The Effect of Gas Slippage on Laboratory Results and Gas Well Production

Abstract:

This paper presents results from a laboratory study comparing Klinkenberg-corrected permeability measurements and apparent permeability measurements in tight gas sands. We also investigated the effects of slippage on laboratory results and gas well production. Our study shows the permeability lose rate caused by the slippage effect and medium deformation is larger than that only caused by medium deformation, comparing the stress sensitivity experimental results. From results of hundreds of experiments, the relationship between slip factor and Klingenberg-corrected permeability was set up by regression, in addition, the theoretical type-curve depicting the effect of slippage on production was plotted with consideration of both permeability and pressure of gas reservoirs. This type-curve is valuable for engineering application to judge the effecting degree of slippage effect on production.
