摘要： A method of completing a wellbore in a subsurface formation is provided herein. The method principally has application to subsurface formations comprising organic-rich rock that is to be heated in situ. Heating the organic-rich rock pyrolyzes solid hydrocarbons into hydrocarbon fluids. The method includes identifying sections along the wellbore where the organic richness of formation rock within the identified zones varies over short distances. Such variance presents a risk of mechanical failure to downhole equipment. The method further includes strengthening the downhole equipment in at least one of the identified sections.

摘要： Selective stimulation ports (SSPs), wellbore tubulars that include the SSPs, and methods of operating the same are disclosed herein. The SSPs are configured to be operatively attached to a wellbore tubular and include an SSP body, an isolation device extending within an SSP conduit of the SSP body, a retention device coupling the isolation device to the SSP body, and a sealing device seat. The isolation device is configured to selectively transition from a closed state to an open state responsive to a shockwave, which has greater than a threshold shockwave intensity, within a wellbore fluid that extends within a tubular conduit of the wellbore tubular. The methods include generating the shockwave within the wellbore fluid such that the shockwave has greater than the threshold shockwave intensity. The methods further include transitioning the isolation device from the closed state to the open state responsive to receipt of the shockwave.

摘要： Systems and methods for bulk heating of a subsurface formation with at least a pair of electrode assemblies in the subsurface formation are disclosed. The method may include electrically powering the pair of electrode assemblies to resistively heat a subsurface region between the pair of electrode assemblies with electrical current flowing through the subsurface region between the pair of electrode assemblies; flowing a shunt mitigator into at least one of the pair of electrode assemblies; and mitigating a subsurface shunt between the pair of electrode assemblies with the shunt mitigator. Mitigating may be responsive to a shunt indicator that indicates a presence of the subsurface shunt.

摘要： 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.
