Laboratory electrical properties and capillary pressure analysis of core samples are useful tools in understanding and calculating oil and gas reserves.Vugular and conglomerate core material present challenges that standard laboratory methodologies can only partially address.This paper presents recent laboratory advances that have been developed to measure capillary pressure and electrical resistivities(a,m and n) in full diameter non-uniform pore geometry systems. First,is a review of the basic methodologies of resistivity measurements(the determination of m and n exponents) and capillary pressure analysis that establish superior data quality.Secondly,the use of a 1000 psi Air/Brine porous plate system with full diameter samples will be demonstrated.The capture on non-uniform electrical and plate capillary pressure response will be discussed.
