Abstract
A system and method for verifying support hanger orientation within a wellhead housing. In an example, a profile is included at a designated location on an inner surface of the wellhead housing. When the support hanger is landed in the wellhead housing, an impression is taken of the inner surface of the wellhead housing from a reference location. Analyzing the impression can indicate the position of the support hanger within the wellhead housing. A running tool that can land the support hanger within the wellhead housing can be equipped with an impression block for taking the impression of the profile in the wellhead housing.
Claims23
A running tool for inserting a support hanger into a wellhead housing that has a profiled inner surface, the running tool comprising:
- a body;
- a support hanger deployment device coupled with the body to be selectively attached to the support hanger;
- and
- an impression assembly coupled to the support hanger, the impression assembly comprising:
- a member that is selectively moveable from a retracted position substantially within the body to an extended position projecting radially outward from the body towards the wellhead housing inner surface, and
- a deformable impression element provided on an end of the member, so that when the member is moved into the extended position, the impression element is pressed against the wellhead housing inner surface and an impression of the wellhead housing inner surface is on the impression element.
A method of landing a support hanger in a wellhead housing having an inner surface with a profiled portion, the method comprising:
- (a) providing a profiled portion in an inner surface of the wellhead housing;
- (b) providing a running tool having a body, a support hanger coupled with the body, and a selectively extendable impression block strategically located at a position on the running coupled with the body;
- (c) inserting the running tool with the support hanger into the wellhead housing;
- (d) landing the support hanger in the wellhead housing;
- (e) forming an impression of the profiled portion of the wellhead housing on the impression block by extending the impression block radially outward and into contact with the profiled portion of the wellhead housing;
- and
- (f) establishing a location of the support hanger within the wellhead based on the impression of the profiled portion.
A method of landing a support hanger in a wellhead housing, the method comprising:
- (a) providing a profiled portion in an inner surface of the wellhead housing;
- (b) providing a running tool having an attached support hanger and a selectively extendable impression block strategically located at a position on the running tool;
- (c) inserting the running tool with the support hanger into the wellhead housing;
- (d) landing the support hanger in the wellhead housing;
- (e) setting a seal between the support hanger and the wellhead housing;
- and
- (f) during the same trip to the wellhead housing as steps (a)-(e), forming an impression of the profiled portion of the wellhead housing on the impression block by extending the impression block radially outward and into contact with the profiled portion of the wellhead housing so that the location in the wellhead housing where the support hanger is landed can be established based on the impression of the profiled portion.
A wellhead assembly comprising:
- a wellhead housing;
- a support hanger coaxially landed in the housing;
- a profile on an inner circumference of the support hanger;
- a running tool inserted within the casing hanger having an impression assembly with a deformable impression element that is selectively moveable from the running tool and to the inner circumference of the support hanger, so that when the deformable impression element contacts the profile, an impression of the profile is made on the deformable impression element thereby establishing a location of the support hanger.
