Abstract
A core sample holder for testing core samples from a well includes a body having a wall defining a cavity. At least two sleeves are disposed within the cavity parallel to each other. Each sleeve of the at least two sleeves is configured to individually hold the core samples. At least one cap is removably coupled to an inner surface of the wall. A tube extends from each end of the at least two sleeves to be a dedicated inlet at a first end of each sleeve and a dedicated outlet at a second end of each sleeve.
Claims18
A core sample holder for testing core samples from a well, the core sample holder comprising:
- a body having a wall defining a cavity;
- at least two sleeves disposed within the cavity parallel to each other, wherein each sleeve of the at least two sleeves is configured to individually hold the core samples;
- at least one cap removably coupled to an inner surface of the wall;
- and
- a tube extending from each end of the at least two sleeves to be a dedicated inlet at a first end of each sleeve and a dedicated outlet at a second end of each sleeve.
A core testing system for testing core samples from a well, the core testing system comprising:
- a core sample holder having a body to hold at least two core and sleeve assemblies parallel to each other within a cavity of the body, wherein each of the at least two core and sleeve assemblies comprises:
- a sleeve;
- a core sample inserted in the sleeve;
- a first plug closing a first end of the sleeve and a second plug closing a second end of the sleeve to isolate the core sample;
- and
- a pair of tubes fluidly coupled to a tubing fitting in the first plug and the second plug to form a dedicate inlet at the first plug and a dedicate outlet at the second plug;
- and
- at least one pump fluidly coupled to the dedicate inlet extending out of the body of the core sample holder, wherein the at least one pump is configured to inject fluids into each of the at least two core and sleeve assemblies.
A method for testing core sample from a well, the method comprising:
- collecting at least two core samples;
- placing each core sample of the at least two core samples individually within a corresponding sleeve to form at least two core and sleeve assemblies in parallel;
- disposing the at least two core and sleeve assemblies within a cavity of a core sample holder;
- applying a target confining pressure to the at least two core samples;
- and
- injecting fluids through the at least two core samples.
