Abstract: The instant invention relates to a wheel disassembly safety system for a multipiece wheel rim (3 and 4) and tubeless tire combination, teaching designs for automatically relieving/releasing pressure as part of its disassembly. Fastening elements (6) used to hold together portions of a wheel rim are provided with a blocking device (20) that prevents loosening and/or removal of the fastening elements until said blocking device is first moved from a blocking position, where movement of the blocking device from its blocking position directly or indirectly opens or requires the opening of a pressure relief channel or channels (23) - allowing, enabling and effecting depressurization of the sealed pressure vessel. This blocking or safety device, typically in the form of a ring, covers all or a critical portion of the nuts/studs (6) that hold the two wheel pieces together. The act of removing this blocking device so as to access and remove the nuts from the studs to disassemble the wheel, opens an air channel in communication with the tire interior so as to allow pressure to escape from the tire interior.

Abstract: A method for forming lateral boreholes from an existing parent wellbore is provided. The wellbore has been completed with a string of production casing. The method generally comprises providing a downhole tool assembly having a whipstock. The method also includes running the assembly down into the parent wellbore. A force is applied to the assembly to cause the whipstock to rotate within the wellbore into an operating position. In this position, a curved face of the whipstock forms a bend-radius substantially across the inner diameter of the casing. A jetting hose is run into the wellbore. Upon contact with the curved face of the whipstock, the jetting hose is re-directed through a window in the production casing. Hydraulic fluid is injected under pressure through the hose to provide hydraulic jetting. The hose is directed through the window and into the formation to create a lateral borehole extending many feet outwardly into a subsurface formation. A downhole tool assembly for forming lateral boreholes from a parent wellbore is also provided herein. The assembly utilizes substantially the entire inner diameter of the casing as the bend radius for a hydraulic jetting hose.

Granted: 2014-08-05
Abstract: A flow conduit may have at least one orifice, which conduit is in the vicinity of a flow source. The source is at least partially covered (and flow blocked by) an optional temporary coating or barrier (e.g. filter cake). The flow pathway between the orifice and the source is temporarily blocked with a degradable material. A delayed degradation material layer is present over or covering the degradable material. The delayed degradation material layer degrades at a rate slower than the degradable barrier. The degradable material and delayed degradation material layer disintegrate (e.g. via time, temperature, a solvent). The degradable material optionally produces a product that removes the temporary coating. The method is useful in one context of recovering hydrocarbons where the flow conduit is the casing or liner of the well and the flow source is a subterranean reservoir where the coating is filter cake.

Abstract: L'invention porte sur un dispositif comportant un oscillateur local (LO) produisant un premier signal comprenant au moins, une information de temps et/ou de fréquence, et/ou de phase, et/ou leurs combinaisons. Le LO comporte également un correcteur d'erreurs présentant une entrée destinée à recevoir un deuxième signal comprenant au moins, une information de temps et/ou de fréquence, et/ou de phase, et/ou leurs combinaisons, ce deuxième signal servant à corriger le LO. Le correcteur d'erreurs du LO corrige le LO en cas de non disponibilité du deuxième signal en utilisant une source moins précise que le deuxième signal. Lorsque le deuxième signal devient au moins temporairement disponible, le correcteur d'erreurs du LO détermine le décalage du LO par rapport au deuxième signal. Si le deuxième signal cesse d'être disponible, avant que le dispositif ne l'ait utilisé pour corriger le LO sur une base continue, le LO corrige son décalage par rapport à l'information de base du deuxième signal obtenue pendant la disponibilité temporaire du deuxième signal, et corrige le LO en utilisant une source moins précise que le deuxième signal, jusqu'à ce que le deuxième signal redevienne plus tard au moins temporairement disponible.
