Abstract: A method of identifying a bed boundary in a subterranean formation by processing data measured by an induction logging tool. An interferometric method compares recorded voltages and/or phases recorded at axially spaced apart receivers on the logging tool. A transmitter is on the logging tool and set between the receivers, where the receivers are equally spaced apart from the transmitter. The transmitter emits a signal having frequencies up to around 50 kHz.

Abstract: A fluid sensor device for measuring properties of a fluid is disclosed. The fluid sensor device includes a leaf cell sensor having a piezoelectric structure acting on a subdomain of the fluid that flows through the piezoelectric structure to create an intrinsic Helmholtz cavity response, and an enclosure enclosing the leaf cell sensor and including (i) a flowthrough shroud having an inlet that allows the fluid to enter the enclosure and pass across the leaf cell sensor, and a Helmholtz cavity wall that couples the intrinsic Helmholtz cavity response with an external acoustic field of the leaf sensor to increase a measurement sensitivity, (ii) a cylindrical housing having an outlet that allows the fluid to exit the enclosure, and (iii) a pressure feedthrough connector that transmits an electrical signal induced by the intrinsic Helmholtz cavity response to represent the properties of the fluid.

Abstract: Systems and methods for producing methane and sulfur. A first system includes a condensate separation system to separate a feed stream of mixed hydrocarbons, an acid gas removal system to produce a methane product stream and a reactant gas stream of carbon dioxide and hydrogen sulfide and a catalytic reactor configured to react the carbon dioxide and the hydrogen sulfide from the reactant gas stream using a carbon-based catalyst and produce an effluent methane stream, an effluent sulfur stream, and a waste stream. Another system for producing methane and sulfur includes a first separation system to separate water vapor and oxygen to produce a hydrogen sulfide stream, a catalytic reactor configured to react a separated carbon dioxide stream and the hydrogen sulfide stream using a carbon-based catalyst and produce a methane stream and a sulfur stream.

Abstract: A method includes providing a distributed acoustic sensing (DAS) system and a fiber sample. The DAS system includes a chamber and a signal generator positioned proximate to and outside the chamber. The method further includes manipulating the fiber sample into a desired shape, filling the chamber with a freezable liquid, wherein the freezable liquid is provided at room temperature, and placing the fiber sample into the chamber. The method also includes recording a first set of room temperature baseline measurements, freezing the freezable liquid, and recording a first set of frozen baseline measurements. The method further includes performing strain-sensing measurements while the signal generator is active, and melting the freezable liquid.

Abstract: Methods and systems are disclosed. The methods may include obtaining, from a subterranean region of interest, a rock sample having a rock type and defining a sequence of pore pressure, confining stress (PPCS) pairs such that a sequence of effective stresses monotonically changes. The methods may further include determining a sequence of permeabilities by subjecting the rock sample to the sequence of PPCS pairs and determining a relationship between the sequence of PPCS pairs and the sequence of permeabilities. The methods may further still include determining a parameter using the relationship and a permeability model, where the permeability model includes the parameter and determining an in situ permeability for an in situ rock in the subterranean region of interest using, at least in part, the parameter and the permeability model, where the in situ rock is of the rock type.

Abstract: A method may include obtaining reservoir data, hydraulic fracturing data, and static wellbore data for a geological region of interest. The method may further include obtaining temporal production data for the geological region of interest. The temporal production data may include a predetermined production rate with respect to a predetermined period of time. The method may further include determining various temporal features based on the temporal production data and an extraction process. The extraction process may include a deconvolution function that separates a portion of the temporal features from the predetermined production rate. The method may further include determining, using a machine-learning model, predicted hydrocarbon-in-place (HIP) data for the geological region of interest using the reservoir data, the hydraulic fracturing data, the static wellbore data, and the temporal features. The method may further include transmitting a command to a well control system based on the predicted HIP data.
