Patent number: 11913303Abstract: Wellbore drilling and completion systems implement a method of completing a wellbore. A laser head is mounted to a wellbore drilling assembly positioned within a wellbore formed in a subterranean zone. The laser head emits a first laser beam in a downhole direction within the wellbore to form the wellbore through the subterranean zone. Doing so causes portions of the subterranean zone to be released as drill cuttings into the wellbore. The laser head emits a second laser beam in a radial direction within the wellbore. The second laser beam is incident on a portion of the drill cuttings. The second laser beam causes the portion of the drill cuttings to consolidate and form a casing of the wellbore.Type: GrantFiled: June 21, 2022Date of Patent: February 27, 2024Assignee: Saudi Arabian Oil CompanyInventor: Sameeh Issa Batarseh
