Publication number: 20210002977Abstract: A thermal expansion system for actuating a remote operated sleeve assembly to open and close ports in a housing for fluidly communicating between a bore of a tubular string in a wellbore to the formation utilizes actuation of a propellant charge to create expanding gas and heat in a combustion chamber to directly act on one side of a piston connected to an axially moveable sleeve supported in the housing to shift the sleeve in one direction. Ignition of another propellant charge in a combustion chamber on an opposing side of the piston is used to directly shift the sleeve in an opposing direction.Type: ApplicationFiled: March 5, 2019Publication date: January 7, 2021Inventors: Per ANGMAN, Mark ANDREYCHUK, Allan PETRELLA, Matthew BROWN

Publication number: 20210002980Abstract: A bottomhole assembly (BHA) having a shifting tool and housing for shifting an uphole-to-open sleeve of a sleeve of a shorter length downhole sleeve assembly to an open position, and optionally to a closed position. Sleeve-engaging elements of the BHA are coordinated to direct the sleeve-engaging elements into a tool-engaging profile of the sleeve, excluding other annular variations in the casing string. The BHA has an improved dual J-Mechanism situated between the shifting tool and housing to permit new additional shifting options which results in fewer overall shifting cycles of the BHA when used with the shift uphole-to-open, shorter-length sleeve assembly. The shortened sleeve assembly is incorporated into a casing string and is relatively short in length when compared with conventional sleeve assemblies.Type: ApplicationFiled: July 6, 2020Publication date: January 7, 2021Inventors: Vitaliy SHPAK, Matthew BROWN, Mark ANDREYCHUK, Per ANGMAN

Patent number: 10871054Abstract: A sleeve assembly has a sleeve axially moveable within a housing, the sleeve being positively locatable within a wellbore for reliable axial shifting of the sleeve between an uphole position and a downhole position. Stops and shoulders, which delimit the shifting of the sleeve between open and closed positions, are located in an annulus between the sleeve and the housing. Uphole and downhole ends of the sleeve and the housing have opposing ramps formed thereon. Locating shifting tools run through the sleeve assembly are engageable only in a locating profile in the sleeve and cannot engage in the annular stops or in gaps formed in the bore, uphole and downhole of the sleeve, as the ramps act to guide the locating tool therethrough. As the uphole and downhole sleeve ramps converge toward either of the uphole or downhole housing ramps during shifting thereof, debris is diverted into the bore allowing the sleeve to shift fully uphole or downhole.Type: GrantFiled: October 12, 2018Date of Patent: December 22, 2020Assignee: KOBOLD CORPORATIONInventors: Mark Andreychuk, Allan Petrella, Per Angman

Publication number: 20200284144Abstract: One or more remote-operated sleeve valves are placed along a tubular string downhole. The sleeves can be opened and closed wirelessly, and in embodiments over and over again. Differential pressure between wellbore fluid pressure and an accumulator chamber enable repeated shifting. Each sleeve can have a unique actuation code removing constraints regarding sequence of operation and need for well intervention to access the sleeves. Hydraulic fracturing can be achieved without wellbore obstructions, and other operations benefit for reduced expense in service rigs and the ability or selectively shut off problem zones. Remote signals received downhole include those generated by percussive and seismic, distinguishable from background noise including during pumping.Type: ApplicationFiled: May 27, 2020Publication date: September 10, 2020Inventors: Mark ANDREYCHUK, Per ANGMAN, Allan PETRELLA

Publication number: 20200217189Abstract: A flow monitoring system can have a plurality of sensors located at monitoring locations along a tubing string inserted into an injector well of a secondary recovery operation. The sensors are configured to monitor a measurable property of fluids flowing in a bore of the tubing string or in an annulus formed between the tubing string and injector bore to determine the presence of said injected fluids at each sensor. At least two fluids having different values of the measurable property are injected into the injector well in an alternating manner and at a known injection rate. The flow rates of the fluids out of various injection zones of the injection well can be calculated using the arrival times and the known injection flow rates of the fluids, cross-sectional area of the fluid conduit(s) through which the fluids travel, and distances between the sensors or between surface and the sensors.Type: ApplicationFiled: January 6, 2020Publication date: July 9, 2020Inventors: Allan PETRELLA, Matthew BROWN, Per ANGMAN, Mark ANDREYCHUK

Publication number: 20200032613Abstract: A resettable elastomeric packer element of a packer, compressed for sealing in a wellbore, is released from sealing engagement in the wellbore by applying tension to an end of the packer element. The elastomeric packer element stretches and releases from the wellbore forming an annular passageway between the packer element and the wellbore. In the absence of a pressure equalization valve or flow passages through the packer, the annular passageway equalizes pressure differentials across the packer element allowing a tool, in which the packer is incorporated, to be moved in the wellbore with little or no damage to the packer element and further, allows debris to flow from above the packer to below the packer.Type: ApplicationFiled: September 25, 2019Publication date: January 30, 2020Inventors: Per ANGMAN, Mark ANDREYCHUK

Publication number: 20200024916Abstract: A shift uphole-to-open sleeve assembly is provided for insertion along a tubular string for multi-stage, selectable wellbore treatment. The sleeve assemblies are very short in length, being too short for in-sleeve engagement, and instead have a downhole shoulder engageable for opening using dogs of a conventional shifting tool. Use of a common J-mechanism having four axial inappropriately places the sealing packer of a downhole tool above the sleeve ports. Multiple extra J-mechanism cycles are required to position the packer downhole thereof. Herein a modified downhole tool is disclosed including a biased repositioning sub to eliminate many of the extra tool cycles. In embodiments the short sleeve can replace casing collars.Type: ApplicationFiled: July 18, 2019Publication date: January 23, 2020Inventors: Mark ANDREYCHUK, Per ANGMAN
