Abstract
A core holder for testing core permeability includes a modular sleeve comprising a series of sleeve segments aligned longitudinally. Port rings positioned between the sleeve segments have radial holes to allow conditions within the core-receiving cavity formed by the sleeve segments and the port rings to be monitored from outside the core holder. The port rings and the sleeve segments are disposed within a housing, and spacer rings are received about the sleeve segments to support the sleeve segments and port rings within the housing. Conditions within the modular sleeve may be monitored through instruments connected to holes in the housing communicating with the holes in the port rings.
