... of penetration (ROP) model. Previously published core and cuttings data for sandstone and shale reservoirs are used to create correlations for UCS and porosity as well as porosity and permeability. Porosity values can be calculated at any UCS values, and applied to the porosity and permeability correlation...

... tests. Of the 61 tests, 18 intervals and 126 point load tests were done in intervals containing salt. The corresponding sonic log values from the same depth interval as the tests were used to calculate UCS values from existing correlations. The UCS values obtained from the available sonic log...
