A cellar around a wellbore is formed or deepened with an excavating system that is capable of being assembled around an existing wellbore. The system includes an excavating unit having an annular body with a cutting surface that excavates cuttings from ground around the wellbore. The cuttings are directed up through a slot in the body, and are collected inside a receptacle set in a recess of the body. An opening is formed in a side of the receptacle when in the body, and through which the cuttings pass from the slot into the receptacle. The receptacle is removable from within the recess and cuttings collected within are emptied. When the receptacle is removed from the recess, the opening is automatically covered to retain the cuttings inside the receptacle. Another cellar around a different wellbore is formed by disassembling the excavating system and relocating it to the different wellbore.

The invention relates to a collecting device for collecting debris of deposits while said deposits are being removed from a wellbore wall or an equipment arranged in a wellbore of a subterranean formation in order to improve the recovery of formation fluids and/or gases, said collecting device being configured for being attached to a cleaning device, said cleaning device being configured for removing deposits from a wellbore wall or an equipment arranged in a wellbore. The collecting device comprises a deflector, configured for deflecting falling debris of deposits while said deposits are being removed from said wellbore wall or said equipment, and a debris storing module, connected to said deflector for collecting and storing debris deflected by said deflector.

The invention relates to a drilling bucket and a method for producing a bore with a drilling bucket, wherein the drilling bucket is driven in a rotating manner and introduced into the ground, wherein ground material is removed and received in an internal space of a tubular base body of the drilling bucket, and for emptying the drilling bucket is withdrawn from the bore and a bottom on the tubular base body is folded open. According to the invention the drilling bucket is rotated in a reversing manner during emptying, wherein ground material received in the drilling bucket is pressed against at least one impact wall and, in doing so, the ground material is specifically compacted and deformed for easier loosening from the internal space.

A floating drift apparatus for verifying the inner diameter of tubulars as the tubulars are made up into a tubular string being run into a wellbore. A float section provides buoyancy to float the apparatus in fluid within the bore of a tubular, and a drift section has a drift element with a diameter substantially equal to the tubular inner diameter being verified, which may be the drift diameter. When running a tubular string, the apparatus is inserted into the bore of the tubular string, floating in the fluid. As joints of tubular are made up and run into the wellbore, the tubulars move downhole around the apparatus. Preferably, the floating drift apparatus can be visually detected. If an undersize ID is encountered, the floating drift apparatus will be pushed downhole and no longer visible; the operator can remove the undersize ID tubular from the string.

Apparatus, and methods of use, where the apparatus includes a cylindrical tool main body defining an axial centerline, the main body having a first bladed magnet section having at least one blade extending substantially perpendicular from the axial centerline at a first angle, a second bladed magnet section having at least one blade extending substantially perpendicular from the axial centerline at a second angle, and a hardfaced cylindrical section disposed between the first bladed magnet section and the second bladed magnet section, wherein the outer circumference of the hardfaced cylindrical section defines the outer circumference of the tool main body.

The present invention provides a method and system for providing on-site electrical power to a fracturing operation, and an electrically powered fracturing system. Natural gas can be used to drive a turbine generator in the production of electrical power. A scalable, electrically powered fracturing fleet is provided to pump fluids for the fracturing operation, obviating the need for a constant supply of diesel fuel to the site and reducing the site footprint and infrastructure required for the fracturing operation, when compared with conventional systems.

A desiccating module configured to be installed in a downhole tool is provided. The desiccating module includes a housing having a containment portion, and desiccant located in the containment portion of the housing capable of retaining moisture therein. The housing is configured to be retained in a downhole tool containing moisture sensitive electronics. The housing is configured to permit passage of moisture from outside the housing to the containment portion and to retain the desiccant within the containment portion. The desiccant have a retention capacity sufficient to hold a predetermined threshold amount of moisture.
