Publication number: 20230417122Abstract: A rig site may include a rotary table within a rig floor above a wellbore. A fabric sheet rolled into two symmetrical rolls is disposed on the rig floor. A pre-cut center hole of the fabric sheet is coaxial with the rotary table. A casing string, to be lowered in the wellbore, includes a first casing joint at a bottom of the casing string is a modified float joint. The pre-cut center hole of the fabric sheet is attached to a sleeve of the modified float joint. Union units are provided above the rotary table. The union units close the fabric sheet around the casing string to form a fabric-nested casing string within the wellbore. A cement slurry is pumped down the casing string and into a space between the fabric sheet and the casing string to cement the fabric-nested casing string to the wellbore.Type: ApplicationFiled: June 28, 2022Publication date: December 28, 2023Applicant: SAUDI ARABIAN OIL COMPANYInventors: Amjad Shaarawi, Mohammad Aljubran, Mohammed Alsheikh, Abdulwahab Aljohar, Timothy Eric Moellendick, Ossama Sehsah

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: 11168524Abstract: A drilling system for forming a wellbore includes a drill string, a drill bit, and a circulation sub in the drill string. Manipulating the circulation sub forms a passage through a sidewall of the drill string; which diverts some of the drilling fluid flowing inside the drill string into the wellbore. Diverting some of the drilling fluid through the passage reduces the amount of drilling fluid flowing in the wellbore between the drill bit and circulation sub, and which optimizes equivalent circulating density of the drilling fluid. Included in an embodiment of the circulation sub is a cylinder that is indexed into set positions by engagement with a J-slot profile in a housing of the circulation sub. A sleeve in the sub is responsive to cylinder positions, and has a port that registers with a slot in the sub walls to form the passage.Type: GrantFiled: September 4, 2019Date of Patent: November 9, 2021Assignee: SAUDI ARABIAN OIL COMPANYInventors: Ossama Sehsah, Ahmad Amoudi, Abdulrahman Khalid Aleid
