摘要： Drill strings with probe deployment structures, hydrocarbon wells that include the drill strings, and methods of utilizing the drill strings are disclosed herein. The drill strings include a pipe string and a drill bit attached to the pipe string. The drill strings also include a probe deployment structure attached to the pipe string and a downhole communication device attached to the pipe string. The probe deployment structure includes a probe and is configured to selectively insert the probe into a subterranean formation via a wellbore of the hydrocarbon well. The probe is configured to measure at least one property of the subterranean formation. The downhole communication device is configured to communicate with the probe. The hydrocarbon wells include a drill string support structure, which supports the drill string, a wellbore extending within a subsurface region, and the drill string extending within the wellbore.

摘要： Cable guides that support a fiber optic cable relative to a tube, hydrocarbon conveyance systems including the cable guides, and methods of acoustically probing an elongate region. The cable guides include a cable retention structure with a first retention region configured to align a first diffraction grating along a first sensing axis and a second retention region configured to align a second diffraction grating along a second sensing axis that is nonparallel to the first sensing axis. The tube defines a tubular conduit configured to convey a hydrocarbon. The hydrocarbon conveyance systems include a tube, a distributed acoustic sensor, and a cable guide. The methods include transmitting an initiated optical signal and receiving a reflected optical signal that includes reflected portions that are reflected by a first diffraction grating and a second diffraction grating. The methods further include analyzing the reflected optical signal to detect an applied mechanical strain.

摘要： Hydrocarbon wells that include interrogation devices positioned within a fracture and methods of monitoring at least one property of a fracture. The hydrocarbon wells include a wellbore that extends within a subsurface region and a fracture that extends from the wellbore. The hydrocarbon wells also include a plurality of interrogation devices entrained within a carrier fluid and positioned within the fracture and a downhole communication device positioned within the wellbore and proximal the fracture. The methods include flowing the interrogation devices into the fracture and conveying the excitation signal into the fracture. The methods also include receiving the excitation signal with the interrogation devices and generating a plurality of corresponding resultant signals with the interrogation devices. The methods further include receiving at least a subset of the corresponding resultant signals with a downhole communication device and determining at least one property of the fracture based upon the corresponding resultant signals.

摘要： A method of measuring a pressure of a fluid adjacent a wall of a pipe or vessel. A transducer is attached to the wall of the pipe or vessel. A signal is transmitted by the transducer at a characteristic frequency via a plurality of guided wave modes. The characteristic frequency is a frequency at which the guided wave modes are separated in time from each other when received. The signal is received after the plurality of guided wave modes travel in or through the wall a predetermined number of times. The signal has a signal receipt time after the predetermined number of times. The pressure of the fluid is calculated using the signal receipt time.

摘要： Hydrocarbon wells and methods for monitoring fracture morphology of a fracture that extends from a wellbore of the hydrocarbon wells are disclosed herein. The hydrocarbon wells include a wellbore, a fracture that extends from the wellbore, and an electromagnetic contrast material positioned within the fracture. The hydrocarbon wells also include a downhole electromagnetic transmitter, which is configured to direct an electromagnetic probe signal incident upon the electromagnetic contrast material, and a downhole electromagnetic receiver, which is configured to receive an electromagnetic resultant signal from the electromagnetic contrast material. The methods include flowing an electromagnetic contrast material into a fracture and generating an electromagnetic probe signal. The methods also include modifying the electromagnetic probe signal with the electromagnetic contrast material to generate an electromagnetic resultant signal. The methods further include receiving the electromagnetic resultant signal and determining the morphology of the fracture.

摘要： Hydrocarbon wells and methods of interrogating fluid flow within hydrocarbon wells. The hydrocarbon wells include a wellbore and downhole tubing that defines a tubing conduit and extends within the wellbore. The hydrocarbon wells also include an interrogation device. The interrogation device is configured to indicate at least one property of fluid flow within the hydrocarbon wells. The hydrocarbon wells also include a downhole location at which the interrogation device is released into the tubing conduit and a detection structure configured to query the interrogation device to determine the at least one property of fluid flow within the hydrocarbon wells. The methods include releasing an interrogation device at a downhole location within a hydrocarbon well and flowing the interrogation device from the downhole location to a surface region. The methods also include querying the interrogation device to determine at least one property of fluid flow within the hydrocarbon well.

摘要： A method and apparatus are provided for determining movement of a fluid into or out of a subsurface wellbore, to thereby enable accurate allocation of fluids being produced by or injected into each of several zones of the wellbore. A temperature change is effected in the fluid in a semi-continuous or pulsed manner at one or more locations in the wellbore. A temperature of the fluid is measured at one or more sensing locations downstream of the location of the temperature change. A time of flight model is used to determine, for a plurality of points of interest, a fluid flow direction, bulk flow rate and/or a cumulative flow rate contribution.
