Patent number: 11130892Abstract: Methods and compositions for suppressing fugitive dust are provided herein. To suppress fugitive dust, particulate materials, dust and or substrates can be treated with a mixture having a hydrophobizing agent and an oil. The hydrophobizing agent can be an organo- or halosilane, a tallow alkylamine, an amine-functionalized polysiloxane, or an amine-functionalized hydrophobic polymer.Type: GrantFiled: December 22, 2017Date of Patent: September 28, 2021Assignee: Trican Well Service Ltd.Inventors: Kewei Zhang, Bill O'Neil, Chuanzhong Wang, Weibing Lu, Harvey Quintero, Grant Farion

Patent number: 10458191Abstract: Tubing encapsulated cable consists of one or more electrical conductors and possibly one or more fiber optic cables sheathed in a corrosion resistant metallic alloy. However, pumping during the installation of tubing encapsulated cable is required to overcome the capstan effect of the tubing encapsulate cable inside the coil tubing as the tubing encapsulated cable travels through the coiled up wraps of coil tubing. In an embodiment of the invention the tubing encapsulated cable consists of one or more electrical conductors and possibly one or more fiber optic cables sheathed in a fiber reinforced composite sheath. Because there is little drag between the fiber encapsulated cable and the coil tubing, conventional pumping operations used to install braided wireline into coil tubing may not be required when installing fiber encapsulated cable into coil tubing.Type: GrantFiled: September 18, 2017Date of Patent: October 29, 2019Assignee: Trican Well Service, Ltd.Inventors: Scott Sherman, Sean Majko

Patent number: 10196560Abstract: Described is a proppant composition comprising particulates coated with a polymeric coating comprising a polymerizable natural oil, and a method of making this composition. The polymerizable natural oil is a glyceryl ester that comprises greater than about 40% by weight of polyunsaturated fatty acids, or a derivative of this ester. The proppant composition is made by mixing particulates with a polymerizable natural oil and polymerizing the polymerizable natural oil to coat the surface of the particulates with polymer comprising polymerized natural oil. The composition may be used in a slurry that is used for hydraulic fracturing operations to improve proppant transportation and to mitigate proppant flowback.Type: GrantFiled: January 29, 2016Date of Patent: February 5, 2019Assignee: TRICAN WELL SERVICE LTD.Inventors: Kewei Zhang, Chuanzhong Wang, Weibing Lu, Leo Liu

Patent number: 9809738Abstract: Described are a method and composition which use microorganisms for downhole applications, in particular for the maintenance or restoration of the integrity of a cement sheath in a wellbore. The method of cementing a wellbore comprises preparing a cement composition comprising a pumpable slurry of cement, water and a healing agent that comprises one or more microorganisms, delivering the cement composition into the wellbore and allowing the cement composition to set. The method of restoring the integrity of a set cement composition in a wellbore comprises preparing a pumpable slurry that comprises water, a healing agent that comprises one or more microorganisms and optionally cement, pumping the slurry into the wellbore in and around the set cement composition, and allowing the one or more microorganisms to grow and replicate to thereby restore the integrity of the set cement composition. Compositions for carrying out the methods are also described.Type: GrantFiled: November 7, 2014Date of Patent: November 7, 2017Assignee: Trican Well Service Ltd.Inventors: Karen Luke, Duane Brownlee

Publication number: 20170306219Abstract: Particulates, such as proppants, that are coated with a coating agent selected from the group consisting of: organosilanes, organosiloxanes, polysiloxanes, long carbon chain hydrocarbon amines containing no silicon or fluoro-based groups in the molecule, amine functionalized polyolefins and polymerizable natural oils; and a chemical additive selected from the group consisting of: a scale inhibitor, a biocide, and an H2S scavenger. The coating agent controls the release of the additive from the particulate surface into surrounding fluid, providing a slow release that promotes the long lasting effect of the additive. The coated particulates have use in oilfield applications such as hydraulic fracturing operations, gravel pack operations, and in water treatment processes.Type: ApplicationFiled: April 21, 2017Publication date: October 26, 2017Applicant: TRICAN WELL SERVICE LTD.Inventors: Harvey QUINTERO, Chuanzhong WANG, Kewei ZHANG, Bill O'NEIL, Weibing LU

Publication number: 20170137695Abstract: By adding a lignosulfonate preferably magnesium lignosulfonate to water and subjecting the mixture to shear a viscous fluid is created. The lignosulfonate increases the viscosity of the water at least to the point where the fluid is viscous enough to maintain the cement in a solution without free water yet not so viscous as to prevent the pumps from moving the viscous fluid slurry and thereby damaging the pumps. The fluid is sufficiently viscous to enable the fluid to conduct the cement slurry through the wellbore and into the formation without duning or otherwise allowing the cement to settle out. Additionally the fluid continues to remain viscous and retain the cement in slurry at temperatures in excess of 225° F.Type: ApplicationFiled: November 13, 2015Publication date: May 18, 2017Applicant: Trican Well Service, Ltd.Inventors: Nisa Monica Shaffer, Marvin Vincent Solomon, SR.

Publication number: 20170015899Abstract: A treatment to temporarily block highly permeable areas in a wellbore having a temperature of less than 160° F. A diverting agent, a catalyzer, and a viscosifier are mixed together and pumped in the wellbore where the treatment flows in the most highly permeable areas. The diverting agent then begins to block those areas as the well is treated finally causing the fluid to divert to other now more highly permeable areas of the wellbore. After less than 48 hours the diverting agent degrades sufficiently to restore the permeablility of the wellbore.Type: ApplicationFiled: September 29, 2016Publication date: January 19, 2017Applicant: Trican Well Service, Ltd.Inventors: Sarkis R.

Patent number: 9458686Abstract: The present invention is directed to a fracturing tool anchor adapted for use with a work string in a wellbore. In one embodiment, the anchor has a housing with a central passage and an uphole and downhole end. The housing has a plurality of ports positioned circumferentially around the housing and along the length of the housing. The ports each contain an engagement member, such as a piston, and a return spring. The engagement member is adapted to extend radially outward when the anchor is pressure activated, to engage the wall of the casing or wellbore. The present application is also directed to a fracturing tool anchor that does not need to be pressure activated and utilizes slips as the engagement members.Type: GrantFiled: August 8, 2012Date of Patent: October 4, 2016Assignee: Trican Well Service Ltd.Inventor: Scott Sherman
