Patent number: 9546313Abstract: Magnesium oxysulfate cement compositions and methods for controlling and preventing fluid and gas flow through a wellbore are described. The compositions and methods may be implemented to provide a barrier to fluid and gas flow between casings or in other operations such as squeeze operations. Magnesium oxysulfate cement compositions may include an admixture of magnesium oxide, magnesium sulfate trihydrate and water. When admixed with water, the compositions rapidly transition from a flowable state to a solid state with formation of little or no gel strength before the transition and further have a near-linear relationship between the time required for the transition to occur and the composition temperature at which the transition occurs enabling the user to determine the time within which the transition will occur. Additives, such as accelerators and inhibitors can be added to modify the time in which the compositions make the transition from flowable state to solid state.Type: GrantFiled: December 13, 2013Date of Patent: January 17, 2017Inventor: Brian Henry Tomlinson

Patent number: 9546316Abstract: This invention generally relates to the field of oil recovery from reservoirs. More specifically, it relates to the recovery of oil from sandstone and carbonate reservoirs using a process for preparing a dispersion of capsules for use downhole including the steps of providing capsules containing a dense liquid, each capsule having a capsule wall defining an inner area, the capsule wall having an outer side. The capsules are functionalized by adding a carbon dioxide-philic compound to the outer side of the capsule wall. A dispersion is then prepared by adding the functionalized capsules to supercritical carbon dioxide such that a stable dispersion of capsules in supercritical carbon dioxide is achieved.Type: GrantFiled: November 8, 2013Date of Patent: January 17, 2017Assignee: Saudi Arabian Oil CompanyInventors: Fawaz Al-Otaibi, Yun Chang, Sunil Kokal, Howard Schmidt

Patent number: 9441471Abstract: Introducing a fluid composition and a heat-generating fluid into a wellbore may improve timing and/or conditions of generating in situ heat downhole. The generated heat may be used to melt wax, and dissolve paraffins and asphaltenes or other deposits within the wellbore or in the reservoir itself. The fluid composition may include a base fluid and a metallic powder having a plurality of metallic powder particles. The base fluid may be or include a drilling fluid, a completion fluid, a stimulation fluid, a workover fluid, an activation fluid, and mixtures thereof. Each metallic powder particle may have a metallic particle core, and a coating disposed on the metallic particle core having a coating material. The metallic particle core may be released from the metallic powder particle. A heat-generating fluid may contact the released metallic particle core and thereby generate heat.Type: GrantFiled: February 15, 2013Date of Patent: September 13, 2016Assignee: Baker Hughes IncorporatedInventors: Kushal Seth, Zhiyue Xu
