Patent number: 11649692Abstract: Before, during, and after a wellbore cementing operation temperature, pressure, and other conditions of a cement slurry are monitored downhole. The monitored conditions are compared to theoretical or calculated conditions to confirm the cementing operation is carried out in downhole conditions as planned. When differences between the monitored conditions and those used in planning the cementing operation exceed an acceptable range, adjustments are made to the cementing operation to account for the differences. The adjustments include changing a composition of the cement slurry to increase its design temperature, wellbore intervention if monitored pressure reveals a backflow of cement, and proceeding with another cementing stage if the monitored conditions indicate the cement slurry has cured into a set cement.Type: GrantFiled: July 14, 2020Date of Patent: May 16, 2023Assignee: SAUDI ARABIAN OIL COMPANYInventors: Abdulaziz Al-Somali, Ossama Sehsah, Tariq Al-Talhi

Patent number: 11041351Abstract: A device for limiting the flow of drilling fluid through a section of drill string is described. The device includes a cylindrical tube with holes in its periphery. Flow enters the device through an upper end of the tube and a portion of the flow exits through the lower end of the tube. In addition, some of the flow is diverted through the peripheral holes. A valve piston is supported near the lower end of the tube by a spring of approximately constant force through its range of travel. The valve piston moves axially as the flow rate through the tube changes flow rate to ensure that a substantially constant amount of flow exits through the lower end, while the excess flow is diverted from the tube through the peripheral holes. A means of damping or stopping the axial movement of the valve piston is included in the device.Type: GrantFiled: December 30, 2019Date of Patent: June 22, 2021Assignee: Dynomax Drilling Tools Inc.

Patent number: 11028685Abstract: A method for determining a rate of penetration of a drill bit during an earth drilling operation may comprise first urging an element to extend out from a working face of the drill bit. As drilling progresses, this extended element may then be forced back into the drill bit by an internal surface of a borehole being formed. A rate at which the element retracts back into the working face may be measured to aid in estimating a rate of penetration of the drill bit into the earth.Type: GrantFiled: July 2, 2018Date of Patent: June 8, 2021Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Malcolm Taylor, Scott R. Woolston, Jonathan D. Marshall, David Hoyle

Patent number: 11002075Abstract: A system for drilling one or more boreholes in a face of a mine passage including markers attached to the mine passage. A drilling machine includes one or more drills for drilling the one or more boreholes, and a first sensor for sensing a position of the markers. Based on the sensed position of the at least two markers, a computer determines: (i) a survey vector generally parallel to the line; and (ii) a face plane generally orthogonal to the survey vector and coincident with a location where the survey vector intersects the face. A controller may be provided for automatically controlling the feeding of the drill(s) based on the location of the face plane and the back plane to form the boreholes in the face. A back plane may also be determined to ensure that all boreholes are drilled to a corresponding depth. Related methods are also disclosed.Type: GrantFiled: July 31, 2019Date of Patent: May 11, 2021Assignee: J.H. FLETCHER & CO.Inventors: Sean Joseph McQuerrey, Adam Teator
