Abstract
Official abstract text for this publication.
A method of testing a core sample is provided. The method comprises determining an impedance map, attaching a sleeve to the core sample, and measuring a flow performance of the core sample. An impedance of each of a plurality of portions of the sleeve is based on the impedance map.
First claim
Opening claim text (preview).
What is claimed is: 1. A perforation test target, comprising: a metal plate; a core sample adhered to the metal plate at one end; and a first sleeve adhered to the core sample, wherein a flow impedance of each of a plurality of portions of the first sleeve is based on a predetermined impedance map. 2. The perforation test target of claim 1 , wherein the first sleeve comprises layers of filter paper, wherein the number of layers at each portion of the fir…
