US Patent:

59154780, Jun 29, 1999

Filed:

Jan 28, 1998

Appl. No.:

9/014845

Inventors:

Henry F. Brown - Enid OK
Jeffrey J. Brown - Enid OK

International Classification:

E21B 3408

US Classification:

166329

Abstract:

An improved standing valve which regulates the amount of accumulated fluid in the tubing string of an oil and gas well, to an amount that is within the purging capability of the gas-lift method. The present invention provides a hydrostatic standing valve with a floating valve seat which is displaced in response to the weight of an accumulated fluid head. A ball seals against the floating valve seat and floats with it, but the displacement of the ball is limited by a positive stop provided by a rod supported by the standing valve body. When the valve seat displaces beyond that of the ball, as limited by the positive stop, the ball is sealingly disengaged from the valve seat and fluid flows out of the tubing string. The dynamic response of the spring to the weight of the fluid head regulates the accumulated head to not exceed a predetermined amount so that the fluid head can be predicted and regulated below an amount that can be reliably purged by conventional gas-lift methodologies, either continuous or intermittent.

International Classification:

E21B 31/12
E21B 33/126
E21B 33/12

Abstract:

The present disclosure is directed toward a downhole tool used to free stuck tools in a wellbore and the method of using the downhole tool. The downhole tool includes at least one packer element for engaging a casing in a wellbore. The packer works to isolate one area of the casing from another. The downhole tool also includes at least one slip element for engaging the casing to maintain the position of the downhole tool in the casing or wellbore. Further, the downhole tool includes a mandrel slidably disposed within the at least one packer element and the at least one slip. The mandrel includes at least one port disposed therein above the at least one packer element when the mandrel is in a first position.
