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.
Claims27
A core stabilization method comprising the step of.
- injecting a stabilizing compound into a core-containing structure though a first subset of a plurality of ports in said core-containing structure.
The method of claim 12 wherein said flow rate of said stabilizing compound is larger that a flow-rate value at which said stabilizing compound sets up before said void space is filled.
A core stabilizing apparatus comprising:
- a core-containing structure having a plurality of ports, a first subset of said plurality of ports adaptable for injecting a core stabilizing compound into said core-stabilizing structure.
A core stabilization method comprising the steps of.
- injection of a gas into an interior of an inner barrel operable for containing a core sample,
- expelling fluid from said interior in response to said injection step, said fluid being retained in said interior after coring of said core sample,
- after expelling said fluid, injecting a core stabilizing compound into said interior of said inner barrel, said stabilizing compound occupying a portion of said interior;
- and
- venting said gas from said interior in response to said injecting step.
A core stabilization method comprising:
- an inner barrel operable for containing a core sample having a plurality of ports in a wall thereof, wherein said ports include a plurality of sets of said ports disposed along a length of said inner barrel, each of said set of ports being disposed about a circumference of said inner barrel;
- a first manifold adaptable for attachment to a first subset of said plurality of ports, said first manifold operable for delivery of a gas through said first subset;
- and
- a second manifold adaptable for attachment to a second subset of said plurality of ports, said second subset of ports being operable for an expulsion of fluid from an interior of said inner barrel in response to said delivery of gas, said fluid being retained in said interior after coring of said core sample, and wherein said second manifold is operable for delivery of a core stabilizing compound when said expulsion of fluid has been substantially completed.
