Patent number: 11591903Abstract: A method for determining a location of a proppant in a subterranean formation includes obtaining a first set of data in a wellbore using a downhole tool. The proppant is pumped into the wellbore after the first set of data is obtained. The proppant is pumped while or after the subterranean formation is fractured. A second set of data is obtained in the wellbore using the downhole tool after the proppant is pumped into the wellbore. The first set of data and the second set of data include a gravitational field measurement. The first and second sets of data are compared, and in response to the comparison, the location of the proppant in the subterranean formation is determined.Type: GrantFiled: May 18, 2021Date of Patent: February 28, 2023Assignee: CARBO CERAMICS INC.Inventor: Souvik Mukherjee

Patent number: 11585185Abstract: An assembly and method of manufacturing an assembly for use as an isolation barrier to be run in and secured within a well. The assembly has a sleeve member positioned on the exterior of a tubular body, fixed at each end to create a chamber therebetween. Fluid can enter the chamber through a port in the tubular body to morph the sleeve member against a larger diameter surface in the well. The sleeve member is formed of at least two materials, welded together and machined before being arranged on the tubular body. One material is more expandable than the other so as to morph more easily. The sleeve is connected to the tubular body by screw threads and seals. Initial construction of the sleeve member allows welding, inspection and machining without affecting the tensile strength of the tubular body or complete assembly.Type: GrantFiled: March 26, 2019Date of Patent: February 21, 2023Assignee: VERTICE OIL TOOLS INC.Inventors: Cameron Hill Radtke, William Luke McElligott, Philip Henry Turrell, Christopher Brian Kevin Cockrill
