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: 11708758Abstract: Hydrocarbon wells and methods of probing a subsurface region of the hydrocarbon wells. The hydrocarbon wells include a wellbore, a downhole sensor storage structure, and a detection structure. The wellbore may extend within a subsurface region and between a surface region and a downhole end region. The downhole sensor storage structure is configured to release a flowable sensor into a wellbore fluid that extends within the wellbore, and the flowable sensor may be configured to collect sensor data indicative of at least one property of the subsurface region. The detection structure may be configured to query the flowable sensor to determine the at least one property of the subsurface region. The methods include releasing a flowable sensor, collecting sensor data with the flowable sensor, and querying the flowable sensor.Type: GrantFiled: September 11, 2020Date of Patent: July 25, 2023Assignee: ExxonMobil Technology and Engineering ComanyInventors: Rami Jabari, P.

Patent number: 11555392Abstract: Methods of completing a hydrocarbon well. The methods include establishing a first fluid seal with an isolation device, forming a first perforation with a perforation device, and fracturing a first zone of a subsurface region with a pressurizing fluid stream. The methods also include moving the isolation device and the perforation device in an uphole direction within a tubular conduit of a downhole tubular that extends within a wellbore of the hydrocarbon well. Subsequent to the moving, the methods further include repeating the establishing to establish a second fluid seal, repeating the forming to form a second perforation with the perforation device, and repeating the fracturing to fracture a second zone of the subsurface region.Type: GrantFiled: September 10, 2020Date of Patent: January 17, 2023Assignee: ExxonMobil Upstream Research CompanyInventors: Rami Jabari, P.

Patent number: 11408275Abstract: Downhole plugs including a sensor, hydrocarbon wells including the downhole plugs, and methods of operating the hydrocarbon wells. The downhole plugs include a sealing structure, an actuation mechanism, and the sensor. The actuation mechanism is configured to selectively transition the sealing structure between a disengaged state, in which the downhole plug is free to move within a tubular conduit of a downhole tubular of the hydrocarbon well, and an engaged state, in which the sealing structure operatively engages with the downhole tubular, forms a fluid seal with the downhole tubular, and resists motion of the downhole plug within the tubular conduit. The sensor is configured to detect a sensed parameter within the tubular conduit and to generate a sensor signal indicative of the sensed parameter.Type: GrantFiled: May 1, 2020Date of Patent: August 9, 2022Assignee: ExxonMobil Upstream Research CompanyInventors: Rami Jabari, P.
