... evaluation of cores, well logs, and actual production data. Past Chicontepec studies have assumed that the porosity exponent ( m ) in Archie and shaly sandstone equations is constant. However, core studies indicate that Chicontepec m values become smaller as porosity decreases. The proposed dual-porosity...
