Patent number: 8881809Abstract: Wireless tag fluid tracking system. A fluid can be tracked in a wellbore utilizing at least one WID tag, such as an LW tag or an RFID tag, entrained in the fluid. A WID tag reader can be disposed and/or displaced in the wellbore, for example, on a drill string or a casing string. A reader can be utilized to locate the at least one WID tag in the wellbore. A reader can be housed in a drill string sub. A fluid entrained with at least one WID tag can be utilized as a tracer fluid. A WID tag can be entrained in cement or a drilling or fracture fluid.Type: GrantFiled: February 28, 2013Date of Patent: November 11, 2014Assignees: Turbo-Chem International, Inc.Inventors: Robin J. Verret, Michael J. Kilchrist

Patent number: 7405182Abstract: A method is provided for reducing lost circulation when aqueous, oil, or synthetic based drilling fluid is used. The method includes injecting two fluids into the well bore and lost circulation zone. The first fluid is an aqueous liquid containing at least one polymer capable of absorbing water in an alkaline environment. The aqueous liquid has a pH that inhibits at least one polymer from absorbing water. The second fluid contains a hardening composition in a base fluid having a pH sufficient to increase the pH in situ to allow at least one polymer to absorb water and expand with the absorbed water and substantially increase in size to close off the lost circulation zone and allow the hardening composition to create a plug in the well bore and set up.Type: GrantFiled: November 30, 2005Date of Patent: July 29, 2008Assignee: Turbo-Chem International, Inc.Inventor: Robin J. Verrett

Patent number: 7297663Abstract: The invention discloses an additive for weighted aqueous slurries to reduce lost circulation during well drilling operations, a method of preparing the additive, and a method of reducing lost circulation utilizing the additive. The additive comprises a hardenable alkaline composition comprising mixtures of diatomaceous earth, finely ground paper, a hydrophobic liquid, micronized cellulose and lime. The hydrophobic liquid decreases the time required to prepare the weighted aqueous slurries, i.e., pills, containing the additive.Type: GrantFiled: March 29, 2005Date of Patent: November 20, 2007Assignee: Turbo-Chem International, Inc.Inventors: Michael J.
