| 20080267786 | Subsea power fluid recovery systems - Systems and methods for recovering power fluid used to power a device under water and for pumping the recovered power fluid to a fluid container above a surface of the water, the method in certain aspects including: flowing fluid from a subsurface apparatus to a subsurface recovery system, the fluid initially provided to the subsurface apparatus to power the subsurface apparatus; and the subsurface recovery system including a pump system for selectively pumping recovered power fluid to a fluid container above a surface of the water, the pump system having at least one pump and, in some aspects, a first pump, a second pump, and a valve system; the valve system controlling the first pump and the second pump to allow only one pump of the first pump and the second pump to pump recovered power fluid to the fluid container above the surface of the water; and pumping recovered power fluid to the fluid container with only one pump at a time. This abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure and is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims, 37 C.F.R. 1.72(b). | 10-30-2008 |
| 20080286534 | Blowout preventers and methods of use - Methods and apparatuses for severing a wellbore tubular, the apparatus, in certain aspects, including: a first member movable toward a tubular to be severed; a second member with a second blade disposed opposite to the first member and movable toward the tubular; a first blade on the first member having a projection projecting from a center of a blade body with point structure on the projection for puncturing the tubular and cutting surfaces on the projection for cutting the tubular; and cutting surfaces, as needed, on the blade body adjacent the projection for cutting the tubular. | 11-20-2008 |
| 20090205838 | Wellbore continuous circulation systems - Systems and methods for continuously circulating fluid, e.g., drilling mud, through a wellbore tubular string, the systems in certain aspects including a sub positionable in fluid communication with the tubular string, the sub with a body, a plug releasably closing off a side opening of the body, and a closure apparatus for selectively closing off flow from the top of the sub into and through the body, while flow is permitted below the closure apparatus through the side opening down through the body into the tubular string; and, in certain aspects, such systems and methods including tubular manipulation apparatus, e.g. an iron roughneck and working with wellbore tubulars with the tubular manipulation apparatus. This abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure and is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims, 37 CFR 1.72( | 08-20-2009 |
| 20100038088 | Multi-function multi-hole drilling rig - A multi-function multi-hole rig is disclosed which, in certain aspects, includes multiple machines for accomplishing rig functions, e.g. drilling machine(s), tripping machine(s), casing machine(s), and/or cementing machine(s), for producing multiple usable wellbores one after the other. This abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure and is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims, 37 C.F.R. 1.72(b). | 02-18-2010 |
| 20100147524 | MULTI-FUNCTION MULTI-HOLE DRILLING RIG - A multi-function multi-hole rig including multiple machines for accomplishing various rig functions, e.g., drilling machine(s), tripping machine(s), casing machine(s), cementing machine(s), workover machine(s), etc., for drilling, completing and/or working over multiple wellbores without moving the rig. Rig functions may be performed one after the other and/or simultaneously, while allowing other functions related to completion and production to continue simultaneously. | 06-17-2010 |
| 20100243324 | SYSTEM AND METHOD FOR COMMUNICATING ABOUT A WELLSITE - A system and method for communicating with a drill string is provided. The system may have an apparatus including a coupler, a frame and an actuator. The coupler may be operatively connectable to a surface system and a downhole system for communication therewith. The frame may be for supporting the coupler and may be operatively connectable to a handling system. The actuator may be for moving the frame with the coupler between an engaged position operatively connected to an uppermost drill pipe of the downhole system and a disengaged position a distance from the uppermost drill pipe whereby the coupler selectively establishes a communication link between the surface system and the downhole system. | 09-30-2010 |
| 20110000670 | BLOWOUT PREVENTERS AND METHODS OF USE - Methods and apparatuses for severing a wellbore tubular, the apparatus, in certain aspects, including: a first member movable toward a tubular to be severed; a second member with a second blade disposed opposite to the first member and movable toward the tubular; a first blade on the first member having a projection projecting from a center of a blade body with point structure on the projection for puncturing the tubular and cutting surfaces on the projection for cutting the tubular; and cutting surfaces, as needed, on the blade body adjacent the projection for cutting the tubular. | 01-06-2011 |
| 20110056168 | WINDMILL INSTALLATION SYSTEM AND METHOD FOR USING SAME - Systems and methods for installing a windmill are provided. The system has a hoisting platform and a carrier. The hoisting platform is operatively connectable to at least one platform leg extending a distance above a base. The hoisting platform is positionable along the platform leg(s). The carrier receives at least one component of the windmill, and is positionable about the hoisting platform and movable thereby whereby the component(s) of the windmill is/are positionable for installation. | 03-10-2011 |
| 20110058918 | WINDMILL CONVEYANCE AND METHOD FOR USING SAME - A conveyance system and method for delivering at least one component of a windmill to a location is provided. The system is provided with a transporter and a transfer system. The transporter is positionable adjacent a base at the location. The transfer system is provided with a plurality of rails, a support and at least one slider. The rails are positionable on the base and the transporter. The support has a first portion of the rails of the transporter thereon.
