Abstract
Provided is a downhole material test sub assembly, a well system including the same, and a method for using the same. The downhole material test sub assembly, in one aspect, includes a flange for coupling to a mandrel, and one or more retainer assemblies coupled to the flange, the one or more retainer assemblies configured to accept a test specimen for running within a wellbore on the mandrel. The downhole material test sub assembly, according to another aspect, includes a mandrel and one or more grooves or pockets located in an outer surface of the mandrel, the one or more grooves or pockets configured to accept a test specimen for running within a wellbore on the mandrel.
Claims29
A downhole material test sub assembly, comprising:
- a mandrel having an outer surface;
- and
- one or more grooves or pockets, wherein the one or more grooves or pockets comprise shaped depressions in the outer surface of the mandrel, the one or more grooves or pockets configured to accept a test specimen for running within a wellbore on the mandrel, wherein the one or more grooves or pockets are shaped to hold the test specimen in tension or compression.
A well system, comprising:
- a wellbore extending into a subterranean formation;
- a tubular located in the wellbore;
- and
- a downhole material test sub assembly coupled to the tubular, the downhole material test assembly including:
- a mandrel having an outer surface;
- one or more grooves or pockets, wherein the one or more grooves or pockets comprise shaped depressions in the outer surface of the mandrel, the one or more grooves or pockets configured to accept a test specimen for running within a wellbore on the mandrel, wherein the one or more grooves or pockets are shaped to hold the test specimen in tension or compression;
- and
- a test specimen accepted within the one or more grooves or pockets.
A method, comprising:
- coupling a downhole material test sub assembly to a tubular, the downhole material test assembly including:
- a mandrel having an outer surface;
- one or more grooves or pockets, wherein the one or more grooves or pockets comprise shaped depressions in the outer surface of the mandrel, the one or more grooves or pockets configured to accept a test specimen for running within a wellbore on the mandrel, wherein the one or more grooves or pockets are shaped to hold the test specimen in tension or compression;
- and
- a test specimen accepted within the one or more grooves or pockets;
- and
- placing the tubular and the downhole material test assembly having the test specimen within a wellbore extending into a subterranean formation.
