Publication number: 20130292113Abstract: A ball catcher for recovering balls from wellbore fluids containing sand during flow back operations. The ball catcher has a receiving chamber for receiving the wellbore fluids containing sand, a first flow outlet for discharging a portion of the wellbore fluids and sand contained therein, and a diverter for redirecting balls entrained within the wellbore fluids. The redirected balls and a balance of the wellbore fluids also containing sand are received in a ball-retaining chamber. A blocker fit to the ball-retaining chamber retains the recovered balls therein while the balance of the wellbore fluids and sand contained therein is discharged from a second flow outlet and directed to downstream equipment through an auxiliary flow line. The retaining chamber can be isolated allowing the balls to be removed from the ball catcher without disrupting the flow back operation.Type: ApplicationFiled: July 11, 2013Publication date: November 7, 2013Inventor: Boris (Bruce) P. CHEREWYK

Publication number: 20130008666Abstract: A method is provided for safely delivering actuators such as balls from a ball injector to a downhole tool in a wellbore. A structure or carrier medium, such as a slug of gel or foam, is introduced to a bore of injector and the ball is injected into the bore for support by the carrier medium. A displacement fluid, such as fracturing fluid, is pumped into the wellbore to drive the carrier medium and ball. Each slug and ball can be retrieved at a ball catcher at the wellhead.Type: ApplicationFiled: July 4, 2012Publication date: January 10, 2013Applicant: ISOLATION EQUIPMENT SERVICES, INC.Inventor: Boris (Bruce) P.

Patent number: 8136585Abstract: An apparatus for successively releasing balls into a wellbore during wellbore operations is disclosed. The apparatus has a radial housing having at least one radial ball array having two or more radial bores. Each radial bore houses a ball cartridge adapted to receive and release balls and an actuator for operably aligning or misaligning the ball cartridge with an axial bore in fluid communication with the wellbore. The ball cartridge is moveable along the radial bore and is operable between an aligned position, for releasing a ball and a misaligned position for storing the ball.Type: GrantFiled: May 12, 2010Date of Patent: March 20, 2012Assignee: Isolation Equipment Services, Inc.Inventor: Boris (Bruce) P Cherewyk

Patent number: 7992635Abstract: A wear-resistant sealing system for introducing fracturing fluids to a wellhead comprising a tubular connector having a retaining shoulder and bridging a flange interface created between a frachead and a lower tubular structure. The tubular connector has upper and lower sealing elements above and below the flange interface and forms a contiguous bore for fluid communication of the fracturing fluids from the frachead to the lower tubular structure and wellhead.Type: GrantFiled: August 8, 2007Date of Patent: August 9, 2011Assignee: Isolation Equipment Services Inc.Inventor: Boris (Bruce) P.

Publication number: 20110048695Abstract: A manifold for distribution of well servicing fluids, such as fracturing fluids, to a plurality of wells. The manifold has a single bore through which the fluid flows and a plurality of outlets which are connected to the bore. Two or more of the outlets deliver the fluid to each wellhead. Valves are positioned in each of the outlets so that each of the wellheads can be independently isolated from the fluids for selecting which of the wells will be serviced at any given time. A total cross-sectional area of the outlets feeding each of the wells is greater than the cross-sectional area of the bore which results in a velocity reduction in the outlets which reduces erosion in the manifold and the downstream components Systems are described using prior art manifolds or manifolds according to embodiments of the invention for use specifically with fracturing fluids containing proppant. Proppant can be delivered to the fracturing fluid through the manifold, directly to the wellhead or both, to reduce erosion.Type: ApplicationFiled: November 3, 2010Publication date: March 3, 2011Applicant: ISOLATION EQUIPMENT SERVICES, INC.Inventors: Boris (Bruce) P.

Patent number: 7735548Abstract: A ball catcher is adapted to be fluidly connected to a wellhead port to receive wellbore fluids and balls carried therewith. A diverter is fit to the catcher body and has a wellhead end positioned to intercept the fluid flow from the wellhead port so as to divert debris and balls carried therein into a ball recovery chamber. The diverter has a bore in fluid communication with the flow outlet and the wellhead end has flow passages formed therethrough to the bore for receiving the fluid flow free of debris and balls and discharging the fluid flow from the catcher body. The diverter and the ball recovery chamber can be connected to quick removal for replacement, repair or cleaning.Type: GrantFiled: June 23, 2008Date of Patent: June 15, 2010Assignee: Isolation Equipment Services IncInventor: Boris (Bruce) P.

Patent number: 7562705Abstract: A packoff nipple for sealing an annular space in a well pipe has a tubular body, a sealing assembly positioned around the tubular body capable of axial movement along the tubular body and a stop to restrain the sealing assembly from extruding into the annular space. The sealing assembly includes one or more elastomeric sealing rings having a circumferential groove formed in a downhole face. An axially moveable actuator, such as a packer cup, engages the sealing ring assembly to cause at least a portion of the sealing rings to expand radially outwardly to seal the annular space and cause the sealing ring assembly to contact the uphole stop. The sealing rings are axially compressed between the uphole stop and the actuator to further expand the sealing rings. The uphole stop may be concave to urge the sealing rings away from the well pipe to avoid extrusion or permanent deformation.Type: GrantFiled: January 28, 2008Date of Patent: July 21, 2009Assignee: Isolation Equipment Services Inc.Inventor: Boris (Bruce) P.
