Abstract
A core sample holder assembly for performing a laboratory magnetic resonance measurement of a core sample taken from a hydrocarbon containing formation is provided. The assembly comprises a pressure chamber provided by a hull and one or more flanges are sealingly coupled with the hull. A flexible core sample holder sleeve is arranged within the pressure chamber and is sealingly coupled with at least one of the flanges. An overburden fluid injection port is in fluid communication with an annular space between the hull and the flexible sleeve and is configured to inject overburden fluid into an annular space between the hull and the flexible sleeve. A pressure regulator is configured to maintain the overburden fluid in the annular space at an elevated pressure. A radio-frequency antenna, within the pressure chamber and wrapped around the sample holder sleeve, is configured to receive an electromagnetic-signal from the core sample. In use, the core sample is arranged substantially within the sleeve.
