Publication number: 20240035348Abstract: A friction reduction tool and assembly are selectively activatable to produce fluid pressure pulses in downhole operations. The assembly includes a variable choke assembly having a rotary component and a stationary component, each with passages that enter into and out of alignment when the rotary component rotates with respect to the stationary component when driven by a rotor. The rotary component, stationary component, and rotor each have a central bore defining a central passage permitting fluid flow from above the assembly to below the assembly.Type: ApplicationFiled: October 13, 2023Publication date: February 1, 2024Inventors: Douglas KINSELLA, Kevin LEROUX, Troy LORENSON, Dwayne PARENTEAU

Publication number: 20230417126Abstract: A flow-through assembly for use in a downhole drilling string includes a Moineau-type motor, means for selectively activating the motor such as a ball catch component that selectively causes drilling fluid to enter into or bypass the motor, and a rotating variable choke assembly that is driven by a rotor of the motor. The choke assembly varies the flow rate of drilling fluid as rotation causes ports of the choke assembly to enter into and out of alignment with each other. In one embodiment, the choke assembly comprises a faceted rotary component including bypass ports on the facets of the component. In another embodiment, the choke assembly comprises a tapered rotary component that rotates in a complementarily tapered stationary component.Type: ApplicationFiled: September 1, 2023Publication date: December 28, 2023Inventors: Troy LORENSON, Kevin LEROUX, Dwayne PARENTEAU, Douglas KINSELLA

Patent number: 10648265Abstract: A method of drilling a substantially lateral section of a wellbore includes extension of a first segment of a drilling string with a bottom hole assembly is extended into a wellbore. At determined intervals of the drilling string, a plurality of friction reduction segments are connected as the wellbore is drilled and the drilling string is extended into the wellbore. The friction reduction segments comprise a friction reduction tool and corresponding activation tool for activating the friction reduction tool. The activation tool selectively diverts drilling fluid into a motor powering the friction reduction tool or away from the motor, and can be a ball catch assembly that is activated when a suitably sized projectile is seated in the assembly. Multiple friction reduction segments can be connected to the drilling string and one or more of the plurality of segments can be activated.Type: GrantFiled: April 12, 2019Date of Patent: May 12, 2020Assignee: IMPULSE DOWNHOLE SOLUTIONS LTD.Inventors: Douglas Kinsella, Kevin Leroux, Troy Lorenson, Dwayne Parenteau

Patent number: 6736224Abstract: A wellbore assembly is provided that is operable in wellbores in the range of six to six and one-half inches for obtaining large diameter cores, e.g., cores greater than or equal to two and seven-eighths inches in diameter. The wellbore assembly may preferably be utilized with drill pipe so that standard drilling rigs may be utilized in drilling and coring operations therewith. The drill pipe in accord with the present invention may be formed by modifying standard API drill pipe such as API four and one-half inch IF (Internal Flush) drill pipe in a special manner that renders the drill pipe still suitable for the type of drilling operations of interest and also suitable for handling by any drilling rig capable of using standard API drill pipe. Alternatively, the drill piper may be initially manufactured in accord with the specifications of the present invention.Type: GrantFiled: March 5, 2002Date of Patent: May 18, 2004Assignee: Corion Diamond Products Ltd.Inventor: Douglas Kinsella
