The sensitivities of production data with respect to capillary pressure model parameters are required when the gradient-based optimization algorithm is used to minimize the objective function. How to calculate the sensitivities of the production data...

For the reservoir and cost conditions considered, the optimum frac length is the most sensitive to variations in porosity, frac cost and pay thickness...

The best match of long term production interference data was obtained with a dual porosity description that included anisotropic, stress-sensitive permeability. In the dual porosity model, both...

... derived constants for a given rock type at a range of differential pressures (geostatic-pore pressure). Domenico's analysis, which assumes normally pressured rock, indicates that, for sandstone, shear-wave sensitivity to Φ is -2.5 times that of compressional-wave sensitivity ( Figure 1 ). Thus in situ...

Using Rabe's recommended method for correcting Gamma Ray logs for drag, sensitivity changes, thin bed effects, and converting to a common scale was found to be entirely laborious. For practical reasons, it was decided to check and see...
