Appl. No.:

12/189479

Inventors:

Brian W. Cruickshank - The Woodlands TX, US
Benjamin Bianchi - Montgomery TX, US
Richard Messa - Lafayette LA, US

Assignee:

Smith International, Inc. - Houston TX

International Classification:

E21B 29/04
E21B 29/00

US Classification:

166 545, 166 546, 166 55, 166298, 166376

Abstract:

A wireline cutter comprises a primary housing with a first axial bore configured to receive a wireline positioned within a well bore, and a first blade mounted within the primary housing and operable to cut the wireline. A method of cutting a wireline in a well bore comprises running a wireline cutter into the well bore, receiving the wireline within the wireline cutter, and cutting the wireline with the wireline cutter. A one-trip cutting system for use in a well bore comprises a wireline cutter, and a coiled tubing cutter. A method for cutting a coiled tubing with a wireline disposed therein comprises running a system comprising a wireline cutter and a coiled tubing cutter into the well bore, cutting the coiled tubing with the coiled tubing cutter, and cutting the wireline with the wireline cutter, wherein both cutting steps are performed in one trip into the well bore.

Appl. No.:

15/428927

Inventors:

Richard Messa - Broussard LA, US
Christopher Gasser - Houston TX, US
Brady Guilbeaux - Maurice LA, US
Ashley Rochon - New Iberia LA, US
Duane Dunnahoe - Broussard LA, US

International Classification:

E21B 29/00
E21B 10/567

Abstract:

A downhole milling tool apparatus for use in milling through hard substances, such as barite, found in underground wells, providing a stepped increase of diameters and positioning of carbide cutters and appropriate positioning of fluid ports and channels, to provide removal of cuttings and cooling and lubricating of the cutting head, in turn providing more efficiency and a better rate of penetration (ROP).

International Classification:

E21B 28/00
E21B 34/14

Abstract:

A downhole pulsing-shock reach extender apparatus for overcoming static friction resistance in coiled-tubing drilling-fluid-pressure driven downhole operations, generating pulsed hydraulic shocks at the workstring by creating a fluid-hammer condition by repeated sudden opening and closing of a valve controlling a diverted portion of the flow of drilling fluid, while maintaining a constant flow of a portion of drilling fluid sufficient to operate and prevent damage to other components of the workstring, thereby extending the depth limit of downhole operations.

International Classification:

E21B 31/00
E21B 17/20
E21B 21/10

Abstract:

A downhole pulsing-shock reach extender apparatus for overcoming static friction resistance in coiled-tubing drilling-fluid-pressure driven downhole operations, generating pulsed hydraulic shocks at the workstring by creating a fluid-hammer condition by repeated sudden opening and closing of a set-pressure snap-acting valve, using an essentially constant or slowly changing normal drilling-fluid pressure that will not damage other components of the workstring, thereby extending the depth limit of downhole operations. A poppet and calibrated spring act as a set-pressure snap-acting valve, and a tapering constriction and constricted throat in the main flow of drilling fluid or mud builds up higher pressure to open the valve, while bypass portways allow for limited flow and equilibration around the valve. The rapid equilibration of pressure upon the opening of the valve, combined with the force of the calibrated spring, allows a rapid closing of the valve, which sets up a fluid-hammer hydraulic shock, in a repeating cycle.
