Abstract
A downhole tool includes a housing having an inner surface. And inner groove is formed in the inner surface. The downhole tool also includes a body positioned in the housing. The downhole tool also includes a plurality of retention members positioned at least partially within the inner groove. The retention members initially prevent the body from moving in a downhole direction relative to the housing. The retention members are configured to yield, which allows the body to move in the downhole direction relative to the housing.
Claims16
A downhole tool, comprising:
- a housing having an inner surface, wherein an inner groove is formed in the inner surface;
- a body positioned in the housing;
- a plurality of retention members positioned at least partially within the inner groove, wherein the retention members initially prevent the body from moving in a downhole direction relative to the housing, and wherein the retention members are configured to yield, which allows the body to move in the downhole direction relative to the housing;
- and
- an installation tool configured to have the plurality of retention members loaded therein and configured to transfer the retention members into the inner groove from within the housing.
A casing float sub for use in a well, the casing float sub comprising:
- a housing having an inner surface, wherein a groove and a shoulder are formed in the inner surface, and wherein the groove includes a slot that has a greater width than a remainder of the groove;
- a body positioned in the housing, wherein the body defines a beveled nose that is configured to fit at least partially through the shoulder;
- and
- a plurality of tabs positioned at least partially within the groove, wherein the tabs are configured to be introduced radially-outward through the slot and into the groove by an installation tool that is configured to have the plurality of tabs loaded therein and configured to be positioned within the housing, wherein the tabs are configured to slide circumferentially within the groove after being introduced via the slot such that the tabs become circumferentially offset from one another within the groove, wherein the tabs are prevented from being removed from the groove when the tabs are misaligned with the slot, wherein each tab has an outer portion and an inner portion, wherein the outer portions form dovetail connections within the groove, wherein the inner portions are configured to contact the body, wherein the inner portions initially prevent the body from moving in a downhole direction relative to the housing, wherein the inner portions are configured to yield in response to a predetermined force exerted therein by the body, which allows the body to move in the downhole direction relative to the housing, and wherein the body is configured to impact the shoulder and break apart after the inner portions yield.
A method, comprising:
- positioning a body in a housing, wherein the housing has an inner surface, and wherein a groove is formed in the inner surface;
- positioning a plurality of retention members at least partially within the groove, wherein positioning the retention members comprises:
- loading the retention members into an installation tool;
- positioning the installation tool, with the retention members loaded therein, into the housing;
- and
- transferring the retention members from the installation tool to the groove in the inner surface of the housing, wherein the retention members initially prevent the body from moving in a downhole direction relative to the housing;
- deploying the body, the housing, and the retention members into a well;
- and
- increasing a pressure of a fluid in the well, which causes the retention members to yield, and wherein the body moves relative to the housing in response to the increased pressure and the retention members yielding.
