Abstract
A core stabilization apparatus and method are implemented. An inner barrel having a plurality of ports disposed circumferentially and axially in a wall thereof is provided. A gas manifold is attached to a first subsets of the ports. Gas is delivered to an interior of the inner barrel via the gas manifold and the corresponding ports. Drilling mud remaining in the interior of the inner barrel is expelled through a second subset of ports. After expulsion of the drilling mud, a stabilizing compound is injected into the interior via an injection manifold attached to the second subset of ports. Upon curing of the stabilizing compound, the inner barrel and core sample contained therein may be sectioned or otherwise manipulated.
Claims16
A core stabilization method comprising injecting a noncryogenic stabilizing compound into a core-containing structure through a plurality of ports in the core-containing structure, wherein the plurality of ports is disposed axially along the core-containing structure.
A core-stabilizing apparatus comprising a core-containing structure having a plurality of ports adapted for injecting a noncryogenic core-stabilizing compound into the core-containing structure, wherein the plurality of ports is disposed axially along the core-containing structure.
A stabilized core product comprising:
- a core sample recovered from beneath the surface of the Earth;
- a core-containing structure having a plurality of ports axially disposed thereon and an interior space, wherein the core sample is disposed within a first portion of the interior space of the core-containing structure;
- and
- a core-stabilizing compound disposed within a second portion of the interior space, the second portion being between the core sample and a bounding surface of the interior space of the core-containing structure, wherein the core-stabilizing compound is injected into the second portion through the plurality of ports.
