  • Patent number: 11891873
    Abstract: Methods and compositions for performing a sealing operation in a wellbore. An example method introduces a sealant composition into the wellbore while the sealant composition is under shear. The sealant composition comprises a thixotropic material, a conformance gel system, and an aqueous base fluid. The sealant composition is placed into a target location, and applied shear is reduced to the sealant composition when in the target location thereby allowing the sealant composition to thicken in the target location. Fluid flow across the target location is reduced by a fluid seal formed by the thickened sealant composition.

  • Patent number: 11867546
    Abstract: A system includes upstream process equipment and downstream process equipment. The upstream process equipment is configured to transmit a predetermined fluid to the downstream process equipment. A manually operated valve fluidly couples the upstream process equipment to the downstream process equipment. A removable ultrasonic wireless flow meter is coupled to piping downstream from the manually operated valve. A control system is coupled to the manually operated valve and the removable ultrasonic wireless flow meter. The control system determines an optimum time and speed to actuate the manually operated valve using a predictive model based on a valve size of the manually operated valve, a valve age of the manually operated valve, fluid type, a criticality index of the manually operated valve, a measured flow rate from the removable ultrasonic wireless flow meter, and corresponding coefficients.
