Abstract
A system includes an annular wellhead housing and an indicator assembly. The annular wellhead housing includes a shoulder and a first passage extending radially through the wellhead housing from an exterior surface of the wellhead housing to an interior surface of the wellhead housing. The indicator assembly is configured to extend through the passage, wherein the indicator assembly, when actuated, is configured to indicate whether a hanger disposed within the wellhead housing has landed on the shoulder.
Claims17
A system, comprising:
- an annular wellhead housing, comprising:
- a shoulder;
- and
- a first passage extending radially through the wellhead housing from an exterior surface of the wellhead housing to an interior surface of the wellhead housing;
- and
- an annular indicator ring disposed axially adjacent to a hanger, wherein the hanger and the indicator ring are configured to couple to a hanger running tool, wherein the hanger running tool comprises an annular recess;
- an indicator assembly configured to extend through the passage, wherein the indicator assembly, when actuated radially inward, is configured to extend into the annular recess of the hanger running tool to indicate that the hanger disposed within the wellhead housing has landed on the shoulder.
An indicator assembly configured to extend through and couple to a test port of a wellhead housing, the indicator assembly comprising:
- an annular housing comprising a passage;
- an indicator pin extending through the passage of the annular housing;
- and
- a spring configured to bias the indicator pin radially outward;
- wherein the indicator assembly, when actuated, is configured to indicate whether a hanger disposed within the wellhead housing has landed on a first shoulder of the wellhead housing, wherein a tip of the indicator pin is configured to contact an annular recess of a hanger running tool when the indicator pin is depressed radially inward and the hanger has landed on the first shoulder, and wherein the indicator pin is configured to contact an indicator ring or the hanger when the indicator pin is depressed radially inward and the hanger has not landed on the first shoulder.
A method, comprising:
- coupling an indicator assembly to a wellhead housing of a wellhead assembly, wherein the indicator assembly comprises an indicator pin configured to extend radially through the wellhead housing, wherein the wellhead housing comprises an annular shoulder;
- coupling an indicator ring to a hanger running tool;
- coupling a hanger to the hanger running tool, wherein the hanger running tool comprises an annular recess configured to receive a portion of the indicator pin when the indicator assembly is actuated and the hanger has landed on the shoulder, and wherein the indicator pin is configured to contact the indicator ring when the indicator assembly is actuated and the hanger has not landed on the shoulder;
- running the hanger and the hanger running tool into the wellhead housing;
- depressing the indicator pin radially inward;
- determining whether the hanger has landed on the shoulder based on how far the indicator pin is depressed before contacting a surface of the wellhead assembly.
