Paper Number: SPE-39810-MS
... upon the permeability equation used. The straight line (representing the flow unit) yields various unique slopes for the different models. This depends upon the porosity exponent that appeared in the permeability equation. In addition, each flow unit model possesses a characteristic intercept...

... and the superposition time function, ?t sup , is defined as Equation 4 According to Eq. 1, a plot of inverse injectivity, (p i -p w )/q N , versus the superposition time function, ?t sup , will yield a straight line with a slope of m and an intercept of b. During an acid treatment, all of the parameters defining...

... reservoirs, the slope and intercept of the decline curve plot are used to estimate reservoir pore volume. However, estimates of skin factor and permeability are required to calculate the reservoir shape factor from either the slope or intercept of the decline curve plot. For naturally-fractured reservoirs...
