Abstract: Systems, computer-implemented methods, and non-transitory computer-readable medium having a stored computer program provide characterization of multiphase fluid flow (MPF) using approximate entropy calculation techniques to enhance measuring and monitoring of a flow regime in a segment of pipe for hydrocarbon-production operations. The systems and methods can be optimized using principal component analysis.

Abstract: Disclosed are systems, methods, and apparatuses to detect one or more downhole laterals in a wellbore using electromagnetic sensors. Certain embodiments include a subsurface unit including a ruggedized encapsulation resistant to heat, pressure, and variations in pH. The systems and apparatuses are communicable with surface controls.

Abstract: The bluff body attaches to an elastic mount and is capable of generate vortex shedding when the elastic mount orients the bluff body in a flow-line traverse to a fluid flow and vibrates in response to the vortex shedding. A harvester is located within the bluff body and is capable of generating power above a specified threshold in response to the vibration.

Abstract: A system for preventing hydrate formation in a pipeline includes a heater housing. The heater housing has an outer diameter sized to travel within the pipeline. A turbine assembly is located within the heater housing. The turbine assembly has a blade that is rotatable by a flow of fluid within the pipeline. An electric heater is located within the heater housing and is electrically connected to the turbine assembly. The electric heater is selectively contacted by the flow of fluid within the pipeline.

Abstract: Processing electronics provide flow data acquisition and telemetry for multiphase flow tomographic ultrasonic transceiver arrays. The processing electronics forms pulse drive signals to cause a tomographic pulse sequence to be emitted. Selected ones of an array of the ultrasonic transceivers emit ultrasonic energy in the tomographic pulse sequence for travel through the multiphase flow. The selected transmitting transceiver is isolated while transmitting it, and the remaining the transceivers are enabled to receive measures of the emitted pulse is after travel through the multiphase flow.

Abstract: Systems and methods for determining characteristics of a fluid in a subterranean well include providing a production pipe extending into the subterranean well to convey the fluids from within the subterranean well to an earth's surface. An x-ray source is located on a first side of the production pipe. An x-ray beam is directed into the production pipe, into the fluids, and out of an opposite side of the production pipe as a resulting beam, with the x-ray source. A level of attenuation of the resulting beam is detected with an attenuation detector located on an opposite side of the production pipe. A fluorescence spectra of the resulting beam is detected with a scattered fluorescence detector located on the opposite side of the production pipe. A fluorescence peak of the resulting beam is detected with a peak fluorescence detector located on the opposite side of the production pipe.
