Patent number: 11762117Abstract: Downhole tools and methods for detecting a downhole obstruction within a wellbore. The downhole tools include a positioning mechanism, which is configured to facilitate positioning of the downhole tool within a target region of a wellbore of a hydrocarbon well, an acoustic pulse generator, which is configured to generate an acoustic pulse within a wellbore liquid that extends within the wellbore and fluidly contacts the downhole tool, and a sensor assembly, which is configured to detect a reflected acoustic pulse within the wellbore liquid. The methods include positioning a downhole tool within a target region of a wellbore, generating an acoustic pulse, propagating the acoustic pulse within a wellbore liquid, and reflecting the acoustic pulse from a downhole obstruction. The methods also include propagating a reflected acoustic pulse within the wellbore liquid, receiving the reflected acoustic pulse, and characterizing the downhole obstruction based upon the reflected acoustic pulse.Type: GrantFiled: October 15, 2019Date of Patent: September 19, 2023Assignee: ExxonMobil Technology and Engineering CompanyInventors: Michael C.

Patent number: 10138707Abstract: A method of completing a well involving remediating a condition of screen-out that has taken place along a zone of interest. The method includes forming a wellbore, and lining at least a lower portion of the wellbore with a string of production casing and placing a valve along the production casing, wherein the valve creates a removable barrier to fluid flow within the bore. The barrier is removed by moving the valve in the event of a screen-out. This overcomes the barrier to fluid flow, thereby exposing ports along the production casing to the subsurface formation at or below the valve. Additional pumping takes place to pump the slurry through the exposed ports, thereby remediating the condition of screen-out.Type: GrantFiled: August 20, 2015Date of Patent: November 27, 2018Assignee: ExxonMobil Upstream Research CompanyInventors: Randy C.
