摘要： A method of analysing a subterranean drilled core sample 10 is disclosed. The steps followed are:- a) providing a drill core sample 10 taken from a subterranean formation; b) producing high-resolution data of at least a section of the drill core sample 10 and creating a 3D before test skeleton of the sample 10 using that data; c) mimic wellbore operations using reservoir conditions core floods; d) producing high-resolution data of at least a section of the drill core sample 10 and creating a 3D after test skeleton of the sample using that data; e) identifying and/or segregating one or more formation damage mechanisms 12 by subtracting the 3D before test skeleton from the 3D after test skeleton to create a 3D change skeleton which shows all the formation damage mechanisms 12; and f) 1) identify one or more individual formation damage mechanisms 12, by conducting segmentation including performing one or more diagnostic analysis techniques on at least a section of the drill core sample 10 and generating individual or combinations of simulated 3D skeletons; and 2) determining the effect of said formation damage mechanism(s) 12 on a chosen characteristic of interest of said drill core sample 10.
