Appl. No.:

09/976845

Inventors:

Thomas F. Bailey - Houston TX

International Classification:

E21B 31107

US Classification:

166301, 166178, 166 651, 175297, 175 73

Abstract:

The present invention generally provides a downhole tool with an improved means of transmitting data to and from the tool through the use of wired pipe capable of transmitting a signal and/or power between the surface of the well and any components in a drill string. In one aspect, a downhole tool includes a body, and a mandrel disposed in the body and movable in relation to the body. A conducive wire runs the length of the body and permits signals and/or power to be transmitted though the body as the tool changes its length.

US Classification:

166382, 166348, 166 882, 166 921, 166 854, 166 855

Abstract:

A holding member provides for releasably positioning a rotating control head assembly in a subsea housing. The holding member engages an internal formation in the subsea housing to resist movement of the rotating control head assembly relative to the subsea housing. The rotating control head assembly is sealed with the subsea housing when the holding member engages the internal formation. An extendible portion of the holding member assembly extrudes an elastomer between an upper portion and a lower portion of the internal housing to seal the rotating control head assembly with the subsea housing. Pressure relief mechanisms release excess pressure in the subsea housing and a pressure compensation mechanism pressurize bearings in the bearing assembly at a predetermined pressure.

Appl. No.:

13/979360

Inventors:

Timothy L. Wilson - Houston TX, US
Albert C. Odell - Kingwood TX, US

Assignee:

WEATHERFORD/LAMB, INC. - Houston TX

International Classification:

E21B 21/10

US Classification:

175 24, 175232, 175 65

Abstract:

A method of drilling a wellbore includes drilling the wellbore by injecting drilling fluid through a drill string extending into the wellbore from surface and rotating a drill bit of the drill string. The drill string further includes a circulation sub having a port closed during drilling. The drilling fluid exits the drill bit and carries cuttings from the drill bit. The drilling fluid and cuttings (returns) flow to the surface via an annulus formed between an outer surface of the tubular string and an inner surface of the wellbore. The method further includes after drilling at least a portion of the wellbore: halting drilling; sending a wireless instruction signal from the surface to a downhole portion of the drill string by articulating the drill string, acoustic signal, or mud pulse, thereby opening the port; and injecting drilling fluid through the drill string and into the annulus via the open port.

Inventors:

Timothy L. Wilson - Houston TX, US

International Classification:

E21B 34/14

US Classification:

166373, 166321

Abstract:

A method and apparatus for circulating fluid in a wellbore includes a bottom sub having a bottom sub port and a mandrel, wherein the mandrel substantially forms an inner bore of the circulating tool and includes a mandrel port. The circulating tool may also include an activation piston that is movable in a first direction and a port piston movable in a second direction when the activation piston moves in the first direction. The circulating tool may further include an inner sleeve coupled to the port piston and movable with the port piston, the inner sleeve having an inner sleeve port in selective communication with the mandrel port. When the inner sleeve port is in communication with the mandrel port at least partially, circulating fluid is allowed to flow through the bottom sub port to the wellbore.

International Classification:

E21B 31113

US Classification:

175297

Abstract:

A jar up, bump down hydraulic drilling jar is described. A hydraulic tripping valve arrangement permits the storage of large amounts of static force before releasing a hammer to strike an anvil surface with substantial force. The hammer is positioned on the mandrel and interacts with the anvil surface in the housing to deliver upward jarring forces, to the drill string. During a downward jarring movement, the tripping valve is opened to prevent pressure buildup and accidental downward jarring; thus, a single-acting drilling jar is formed.

Abstract:

A wellbore mill has been invented having a flexible main body, and at least one milling apparatus secured on the flexible main body. A wellbore mill has been invented having a main body with a top end and a bottom end, at least one milling structure on the mill body, and a stinger projecting down from and releasably secured to the bottom end of the mill body. Methods have been invented for milling wellbore tubulars with such mills. A method for eliminating tubular offset in a wellbore has been invented, and the method includes positioning a wellbore mill in a tubular offset of a tubular string in a wellbore, the wellbore mill comprising a flexible main body and at least one milling apparatus secured on the flexible main body, and rotating the wellbore mill to mill at least part of the tubular offset.
