CROSS-REFERENCE TO RELATED APPLICATION

This application is the National Stage of, and therefore claims the benefit of, International Application No. PCT/US2016/068046 filed on Dec. 21, 2016, entitled “DETERMINATION OF PORE SIZE DISTRIBUTION OF RESERVOIR ROCK,” which was published in English under International Publication Number WO 2018/118044 on Jun. 28, 2018. The above application is commonly assigned with this National Stage application and is incorporated herein by reference in its entirety.

BACKGROUND

An important physical property of the reservoir rock affecting the production and economic viability of reservoir extraction operations is the distribution of pore sizes in the rock. Typically the pore size distribution is determined by extracting cores from the reservoir for laboratory analysis. The cores may be subjected to cleaning and surface analyses such as mercury injection porosimetry or to destructive modification into optical petrology slides for analysis by point counting geometric features as a metric for statistics on thin sections to assign pore body dimensions and pore throat distribution to the sample.

These analytical approaches can have deficiencies including, high costs associated with coring, long times required for analysis in labs, and unreliability, for example, due to undesirable alterations to cores or the selection of non-representative core samples. Therefore, there is a continuing need to improve methods and apparatuses for determining the pore size distribution of reservoir rock.
