Filed:

Dec 13, 2004

Appl. No.:

11/010989

Inventors:

James May - Houston TX, US
Larry Moeller - Houston TX, US
Jackson Debray - The Woodlands TX, US
Joe W. Reeves - Corpus Christi TX, US

Assignee:

Smith International, Inc. - Houston TX

International Classification:

E21B 3/02
E21B 19/24

US Classification:

175 57, 175195, 166 781, 166 843

Abstract:

Methods and apparatus for rotating a stripper assembly in use with a rotating drilling head. A drive system is disposed external to the rotating drilling head and generates rotational motion to match the rotation of a drillstring running through the rotating drilling head. A connection transfers rotational motion from the drive system to the stripper assembly. In one embodiment, the drive system comprises a housing disposed about the drillstring and a one or more contact members connected to said housing and operable to contact the drillstring. One or more biasing members urge the contact members into contact with the drillstring so as to transfer rotational motion from the drillstring to the housing.

US Classification:

166367, 166339, 166358, 166381, 166387, 166 843

Abstract:

A riser assembly includes a rotating control housing connected between an upper portion and a lower portion of a riser assembly, and a packing element rotatable with respect to the rotating control housing, wherein the packing element is configured to isolate an annulus of the lower portion from the upper portion when a drillstring is engaged through the packing element, and wherein the packing element is configured to be retrieved and replaced through the upper portion.

Jason Duhe - Missouri City TX, US
James May - Houston TX, US

Assignee:

M-I L.L.C. - Houston TX

International Classification:

E21B 21/08
E21B 47/06

US Classification:

175 57, 175 25, 175 48, 16625007, 16625008

Abstract:

A method for maintaining pressure in a wellbore during drilling operations includes the steps of providing fluid from a reservoir through a drill string, circulating the fluid from the drill string to an annulus between the drill string and the wellbore, isolating pressure in the annulus, measuring pressure in the annulus, calculating a set point backpressure, applying back pressure to the annulus based on the set point back pressure, diverting fluid from the annulus to a controllable choke, controllably bleeding off pressurized fluid from the annulus, separating solids from the fluid, and directing the fluid back to the reservoir. An apparatus for maintaining pressure in a wellbore during drilling operations includes an adjustable choke for controllably bleeding off pressurized fluid from the wellbore annulus, a backpressure pump for applying a calculated set point backpressure, and a processor for controlling the adjustable choke and backpressure pump.

International Classification:

E21B 17/00

US Classification:

175320

Abstract:

A drill pipe () having an elongate tubular body () with an interior surface enclosing a main bore () which extends generally parallel to a longitudinal axis (A) of the tubular body () from a first end to a second end of the tubular body (), a side port () provided in an exterior surface of the tubular body (), a side bore () extending through the body () from the main bore () to the side port (), and a valve assembly () which is operable to substantially prevent flow of fluid along the main bore () and to substantially prevent flow of fluid along the side bore (), wherein the valve assembly (), side port () and side bore () are provided in a first connection portion () of the drill pipe () at the first end thereof, the first connection portion () comprising a thickened portion of the tubular body () in which the separation of the interior surface and the exterior surface is substantially greater than the adjacent portion of the tubular body (), the length of the connection portion () parallel to the longitudinal axis (A) of the tubular body () being less than 64 cm.

Assignee:

Smith International, Inc. - Newport Beach CA

International Classification:

E21B 1030

US Classification:

175228

Abstract:

A reamer used in earth boring by the rotary method includes a body having a plurality of sockets in its outer periphery. Upper and lower blocks are disposed in the socket for supporting a shaft. A roller is rotatably mounted on the shaft with the inner periphery of the roller and the outer periphery of the shaft providing bearings for the roller. The shaft has an upper annular shoulder with a downwardly facing sealing surface disposed above the bearings. Upper and lower seals are disposed above and below the bearings with the upper seals having a facing seal sealingly engaging the roller and the downwardly facing sealing surface on the shoulder of the shaft.
