  • Patent number: 9708869
    Abstract: A formulation for use as a lost circulation preventive material is a cement-forming aqueous fluid comprising water, at least one viscoelastic surfactant (VES), at least one monovalent or multivalent salt, at least one magnesium powder, and at least one retarder. The formulation is used in a method of drilling into a subterranean formation that includes introducing into a wellbore passing at least partially through the subterranean formation the cement-forming aqueous fluid, and further increasing the viscosity of the aqueous fluid by the action of the VES forming elongated micelles; where the at least one monovalent salt is present in an amount effective to pseudo-crosslink the elongated VES micelles to further increase the viscosity of the aqueous fluid. The formulation further forms a cement by reacting the at least one magnesium powder and the water which reaction is retarded by the retarder. The water may be saline water.

  • Patent number: 9243471
    Abstract: A plug for a seal bore in a packer mandrel has a shiftable annular member that can selectively open bypass ports to facilitate latching and then be shifted as part of a release from the plug by a running tool to close the bypass passage that go around a frangible barrier that will later be broken by impact force. The annular member has minimal structure internally to allow attachment of the running tool. The annular member drillout proceeds quickly with minimal cuttings and the frangible member is broken by impact. On an assembly with multiple packers getting plugs a trip is saved as a plug is delivered into a lower packer with a string supporting the packer above. The plug is set in the lower packer allowing release of the running string for subsequent placement and setting of the next packer in the same trip.

  • Patent number: 9121226
    Abstract: A method of hydraulically activating a mechanically operated wellbore tool in a bottom hole assembly includes: holding moveable elements of the wellbore tool in an unactivated position using a shear pin; inserting one or more drop balls into a drilling fluid; and flowing the drilling fluid with the drop balls to a flow orifice located in or below the wellbore tool. The flow orifice is at least partially plugged with the drop balls to restrict fluid flow and correspondingly increases the hydraulic pressure of the drilling fluid. The hydraulic pressure is increased to a point beyond the rating of the shear pin, thereby causing the shear pin to shear and allowing the moveable elements of the tool to move to an activated position.

    Abstract: A method of fracturing a subterranean formation while drilling, applying a new combination of completion techniques. When combined to work simultaneously together, these techniques have synergistic amplified benefits, dynamically opening fissures deep into the production zone. The saturated saltwater phase of the drilling fluid dehydrates all the clays and shale that are drilled through, by osmosis-opening up or enlarging production channels or paths while the relaxed filtrate penetrates further into the wall of the well bore through the naturally occurring fissures or channels in the formation. The saturated salt water fluid with a relaxed filtrate combines with a (0.5-5% by volume) variety of acids (encapsulated by natural oils or polymers) to acid etch or scour the clay or shale walls leaving an acid etch matrix of channeling for later hydrocarbon production.

    Abstract: System and method for predicting the mud weight window in formations, particularly those formations having geologic structures such as salt domes. One embodiment is a computer-implemented method of modeling a formation in 3-D and determining a plurality of effective stress ratios for the modeled 3-D formation using finite element analysis. Thereafter, the trajectory of a proposed wellbore through the 3-D modeled formation is plotted and the specific effective stress ratios along the wellbore are selected to form a data set. The 3-D data set of effective stress ratios is then imported into 1-D modeling software and combined with 1-D data. The combined data is thereafter utilized to estimate the mud weigh window for the formation around the wellbore.

  • Patent number: 8822385
    Abstract: Nanoemulsions have been discovered to be useful to the oil field. More particularly water-in-oil (W/O), oil-in-water (O/W) and other classes of nanoemulsions have found beneficial application in drilling, completion, well remediation and other oil and gas industry related operations. Additionally, nanoemulsions may reduce friction pressure losses, as well as reduce subsidence of solid weight material during oil and gas operations. New preparation methods for nanoemulsions have also been discovered.

  • Patent number: 8813870
    Abstract: An arrangement in a rock drill rig 10 has an inlet valve 31 arranged upstream from a displacement compressor 32 that is used for supplying an air flow 34 to at least one flushing hole 23 in the surface of a drill bit 20. The rock drill rig 10 also has an air regulator 35 arranged to regulate the system pressure in the air flow path 34 downstream from the compressor and a detector for detecting air flow through the at least one flushing hole 23 in the surface of the drill bit. The detector has a pressure sensor 36, arranged between the air regulator 35 and the inlet valve 31, for measuring the reduced system pressure.

  • Patent number: 8813872
    Abstract: A drilling fluid delivery system for drilling boreholes with a drill bit, includes a primary flow circuit having a relatively high flow rate for transferring drilling fluid to and from the drill bit. The system also includes a secondary flow circuit having a relatively low flow rate for transferring drilling fluid to and from the primary flow circuit. Furthermore, the system includes a cuttings transfer system, such as a hydrocyclone or a rotating filter, between the primary and secondary flow circuits. When the cutting transfer system is in use, it receives fluid containing cuttings from the primary circuit and separates the fluid into a first stream that contains substantially no cuttings and a second stream containing cuttings. The first stream is returned to the primary flow circuit and the second stream is directed to the secondary flow circuit.

  • Publication number: 20140231146
    Abstract: The present invention relates to methods of drilling a wellbore wherein a drill-in fluid is foamed at the drill tool. A method in accordance with the present invention comprises providing a drill-in fluid comprising an aqueous fluid, a foaming agent, a foam stabilizer, a gas generating chemical and an encapsulated activator; introducing the drill-in fluid downhole into a drill string connected to a drill tool; and allowing the drill-in fluid to exit the drill tool where, upon exiting the drill tool, the encapsulated activator is de-capsulated sufficiently to react with the gas generating chemical such that a gas is generated within the drill-in fluid and thus foams the drill-in fluid.
