  • Patent number: 8939202
    Abstract: A fracturing jet nozzle assembly features a series of angles nozzles on a rotatably mounted plate that operates in conjunction with a central nozzle or nozzles. The slanted nozzles are aimed into the perforation where the central nozzle is aimed directly so that the rotation of the nozzle plate from the slanted nozzles results in cyclic impacts in the perforation from where the fractures will propagate. The cyclic loading results in greater fracture formation and propagation. In another variation, relatively movable plates employing slanted nozzles rotate one plate with respect to another to get the effect of cyclic pulses of jetting fluid impingement in the perforation to enhance formation and propagation of fractures from the perforation.

  • Publication number: 20140076573
    Abstract: A downhole tool cleans debris from a subsea well with nozzle assemblies that selectively deploy from the tool. The nozzle assemblies are in fluid communication with an annulus of a drill pipe on which the downhole tool is mounted, so that fluid pumped into the drill pipe discharges from nozzles provided with the nozzle assemblies. The nozzle assemblies are strategically situated so that when deployed, a stream discharged from nozzles on the assemblies clears debris from a surface between a casing hanger and wellhead housing. The nozzle assemblies are coupled to an annular piston coaxially set on the tool; and sliding the piston axially along the tool deploys the nozzle assemblies. Axially spaced apart ports extend radially through the tool to opposing faces on a head of the piston. Blocking one of the ports with a ball dropped down the drill pipe moves the piston and deploys the assemblies.

  • Patent number: 7051821
    Abstract: An adjustable hole cleaning device is provided for cleaning a hole in a subterranean formation. A drillstring containing the device is rotated to drill a hole through the subterranean formation. While rotating the drillstring, drilling fluid is circulated through the drillstring and the device into the hole. In response to an increase in a hydrostatic pressure of the fluid in the drillstring, cleaning elements are extended from the device to clean accumulated cuttings from the drilled hole. The cleaning elements may clean the accumulated cuttings by agitating the circulating fluid in the hole. In response to a decrease in a hydrostatic pressure of the fluid in the drillstring, the cleaning elements may be retracted back into the device. The device may also include a set of ports which hydraulically open in response to the increase of hydrostatic pressure in the drillstring to disperse drilling fluid into the hole for cleaning accumulated cuttings.

  • Patent number: 6758276
    Abstract: A tubular body or mandrel incorporated into a string of tubular pipe, on which first and second swab cups and first and second metal brushes and a casing scraper are mounted, is run into a cased earth borehole to displace a first fluid in the borehole, usually a drilling fluid, with a second fluid, usually either a completion fluid or a workover fluid. In a first embodiment, reverse circulation, in which the second fluid is pumped into the borehole annulus above the swab cups and/or the metal brushes, and in which the first fluid is thereby pumped back towards the earth's surface through the interior of the string of tubular pipe, causes displacement of the first fluid merely by lowering the string of pipe while pumping the second fluid into the borehole annulus.

  • Patent number: 6082473
    Abstract: A non-plugging nozzle and self-cleaning drilling tool incorporating the nozzle is provided. The nozzle has a body that defines a central passageway extending axially from the top to the bottom of the body. The central passageway defines an inlet orifice at the top and an exit orifice at the bottom. A side passageway extends through the side wall of the nozzle and communicates with a cylindrical portion of the central passageway, the intersection of which defines a side inlet orifice that is substantially square. Because the intersection is substantially square, particles may not become trapped within the nozzle and plug the side passageway. When incorporated into a drilling tool, particularly a polycrystalline diamond compact (PDC) bit, the drilling tool becomes self cleaning. The side passageway of the nozzle is directed at the voids formed in the cutting face of the drilling tool creating a cross flow through the voids and preventing accumulation and balling therein.
