Patent number: 11713414Abstract: Polyacrylamide (PAM) compositions and methods of using the compositions as drag reducers in well treatment fluids are disclosed. The compositions use PAM particles with log-asymmetric particle size distributions. For example, about 10% or more of the PAM particles may have particle sizes above 76 ?m, but the particle size distribution tails toward lower particles sizes. Dry PAM formulations and premixed concentrate compositions are disclosed. Well treating fluids prepared using the disclosed compositions reach maximum drag reduction very quickly and also exhibit high sustained drag reduction.Type: GrantFiled: August 26, 2021Date of Patent: August 1, 2023Assignee: TUCC Technology, LLCInventors: James W. Dobson, Jr., Rickey L. Warmack

Patent number: 10563111Abstract: The invention provides concentrates for reducing the fluid loss on an oil base well drilling or servicing fluid, the concentrates comprising an oleagineous liquid and (1) a polymer which is solublized in the oleagineous liquid, or (2) a polymer which is solublized in the oleaginous liquid together with an organophilic polyphenolic material which is solublized and/or dispersed in the oleagineous liquid. The method of preparing the concentrate and the method of reducing the fluid loss of an oil base well drilling or servicing fluid utilizing the concentrates is also disclosed. The preferred oil soluble polymer is a styrene-butadiene rubber crumb. The preferred oleagineous liquid is an aromatic-free hydrogenated oil essentially containing only saturated hydrocarbons. The preferred polyphenolic material is a source of humic acid, such as mined lignite.Type: GrantFiled: February 28, 2017Date of Patent: February 18, 2020Assignee: TUCC Technology, LLCInventors: James W.

Patent number: 10253248Abstract: Treating fluid compositions for use in hydrocarbon recovery operations from subterranean formations are described, as well as methods for their preparation and use. In particular, treating fluid compositions are described which comprise a liquid, a crosslinkable organic polymer material that is at least partially soluble in the liquid, a crosslinking agent that is capable of increasing the viscosity of the treating fluid by crosslinking the organic polymer material in the liquid, and a crosslinking modifier additive which can delay or accelerate the crosslinking of the treating fluid composition. Such compositions may be used in a variety of hydrocarbon recovery operations including fracturing operations, drilling operations, gravel packing operations, water control operations, and the like.Type: GrantFiled: September 29, 2015Date of Patent: April 9, 2019Assignee: TUCC Technology, LLCInventors: James W.

Patent number: 10160897Abstract: Disclosed is an alkaline earth metal peroxide concentrate, or fluidized suspension, for addition to aqueous hydraulic fracturing fluids to efficiently decrease the viscosity of the hydrated, hydrophilic polysaccharide polymer in the system. The concentrate comprises a hydrophobic, water insoluble liquid, an organophilic clay suspension agent, a polar activator, a sparingly-soluble alkaline earth metal peroxide, and an anionic surfactant. Advantageously, these concentrations, or suspensions, exhibit high flash points, making them easier to transport using commercial transportation means.Type: GrantFiled: August 3, 2017Date of Patent: December 25, 2018Assignee: TUCC Technology, LLCInventors: James W. Dobson, Jr., Shauna L. Hayden, Kim O. Tresco

Patent number: 9969927Abstract: A treatment fluid composition for treating a subterranean formation penetrated by a well bore is formed from an aqueous fluid, a hydratable polymer and an inorganic peroxide breaking agent, which is classified as a stable, non-oxidizer according to UN standards but which retains oxidizing properties as measured by the content of available oxygen. A method of treating a subterranean formation penetrated by a well bore may also be performed by forming a treatment fluid from an aqueous hydrated polymer solution. This is combined with a stable, inorganic peroxide breaking agent. The treating fluid is then introduced into the formation. An optional crosslinking agent capable of crosslinking the polymer may also be included.Type: GrantFiled: May 23, 2014Date of Patent: May 15, 2018Assignee: TUCC Technology, LLCInventors: James W. Dobson, Jr., Shauna L. Hayden, Kim O. Tresco

Patent number: 9856409Abstract: A water-based drilling fluid which includes an aqueous fluid and a water-soluble dissipative surfactant composition is described, wherein the dissipative surfactant composition includes at least one fatty acid or ester derivative of a plant or vegetable oil. Also described are methods of using such aqueous-based drilling fluids including the dissipative surfactant composition as described in hydrocarbon recovery operations associated with oil/tar sand, where such fluids act to increase the dispersant qualities of hydrocarbons within the oil/tar sand, and where such fluid exhibit a reduced coefficient of friction.Type: GrantFiled: January 30, 2015Date of Patent: January 2, 2018Assignee: TUCC Technology, LLCInventors: James W. Dobson, Jr., Kim O. Tresco, Pierre J. Hinds

Patent number: 9850417Abstract: A fluid pressure transmission pill (FPTP) having an ultra-high viscosity for use in association with hydrocarbon drilling and exploration operations, particularly, managed pressure drilling (MPD) operations, is described. The ultra-high viscosity pill is a weighted pill composition that includes a hydrocarbon fluid, a thixotropic viscosifying agent, one or more activators, an emulsifier/wetting agent, a fluid loss control additive, and a weighting material. In accordance with selected aspects of the described fluid pressure transmission pill, the ratio of the amount of the thixotropic viscosifying agent to the activator is a ratio of about 7:1, and the weighting material is a barium-containing solid-phase material. Also described are methods of use of such FPTP products in subterranean operations, such as well killing operations during managed pressure drilling.Type: GrantFiled: January 11, 2013Date of Patent: December 26, 2017Assignee: TUCC Technology, LLCInventors: James W.

Patent number: 9816025Abstract: Disclosed are treating fluid compositions for use in subterranean workover and hydrocarbon recovery operations, as well as methods of treating subterranean formations penetrated by a wellbore utilizing the treating fluid. The treating fluid compositions contain a first, aqueous liquid, and a crosslinkable organic polymer that is at least partly soluble in the liquid. The treating fluid further contains a borate crosslinking agent solution containing a primary, un-refined borate and a secondary, refined borate, the borate solution being present as a crosslinking agent upon addition to the first fluid admixture so as to crosslink the organic polymer and increase the viscosity and/or accelerate the crosslink time of the treating fluid.Type: GrantFiled: July 9, 2013Date of Patent: November 14, 2017Assignee: TUCC Technology, LLCInventors: James W.
