... measurements are required to accurately characterize the changing cutoffs. In this paper, we propose a novel workflow to derive the porosity and permeability net pay cutoffs by integrating core Mercury Injection for Capillary Pressure (MICP) test and core porosity and permeability, therefore reducing the need...

... Abstract A major drawback in the optimal use of historical core data in reservoir description and exploitation is that most of the core porosity and permeability data are measured at ambient or near ambient conditions of 200 or 400 psi. The use of ambient core porosity and permeability data...

... is established between core porosity and core permeability k; (2) in uncored wells, log porosity is used instead as input; (3) the same equation is sometimes used again to populate the cells of a dynamic reservoir model in 3D, where input porosity values are obtained by interpolation. The core-scale regression...

... case, the uncertainties associated with the log-derived estimates can be quantified. In general, the mean difference between log and core porosities should be less than 0.6 p.u., that between log and core permeabilities should be less than a factor of 1.5 and between log and capillary pressure...

..., the following inequality holds, and the core porosity will equal the ‘total’ porosity when the core is fully dried, (2) Φ t ≥ Φ c o r e ≥ Φ e Φ e must also be greater than Φ core (1 – S wcore ), so that there is sufficient effective pore volume to contain all...
