Abstract: Rock properties of a geological formation may be determined using data representing elemental concentration within the geological formation. For example, the data representing the elemental concentration within the geological formation may be provided as input to a mapping function. The mapping function may capture nonlinear relationships among the concentrations of measurable elements in geological rock formation(s) and certain rock properties of said rock formation(s). Embodiments of the present disclosure are directed to techniques that improve determinations of rock properties of geological formations.

Abstract: Among other things, methods and systems are described for calculating formation breakdown pressures. A method involves determining, during hydraulic fracturing operations, a pore pressure for a wellbore; determining a poroelastic stress for the wellbore using a poroelastic stress equation and based on the pore pressure; determining, during the hydraulic fracturing operations, a breakdown pressure upper bound for the wellbore; applying, during the hydraulic fracturing operations, a stress correction on the breakdown pressure upper bound based on whether the wellbore is an open hole wellbore or a cemented liner wellbore; and determining, during the hydraulic fracturing operations, a breakdown pressure for the wellbore based on the stress-corrected upper bound breakdown pressure for the wellbore.

Abstract: An apparatus and method for operating a new well includes receiving a plurality of data relating to drilling operations from a plurality of wells in a region, the data including data from a plurality of sensors at each of the plurality of wells and data regarding equipment used for the drilling operations at each of the plurality of wells. A plurality of parameters is calculated based on the collected data from the plurality of wells. At least one equipment and at least one operating parameter are identified to use for drilling operation of the new well within the region based on the received data and the calculated parameters. The identified at least one equipment and at least one operating parameter are applied to use for the drilling operation of the new well.

Abstract: Slotted dipole antennas for use in an antenna system on a drill collar segment is presented. Dipoles may be placed in slots on the drill collar segment. A dipole consists of a ferrite rod with electric wires placed above and below the ferrite rod. Wires may be connected such that wire current forms a loop around the ferrite rod. When a group of slots are used for an antenna, wire holes are constructed between slots. Effectively a single wire may be used to go above all ferrite rods in the group and then turn to go below all the ferrite rods. Two wire segments are in a wire hole connecting two adjacent slots. Currents in the two segments are the same in magnitudes and flow in opposite directions. There is no net current in wires in a wire hole.

Abstract: A method is provided to determine and mitigate one or more downhole events of a drill string in a wellbore. The method includes receiving, via a processor, drilling data from one or more surface sensors. The drilling data is processed into a plurality of segments. Each of the plurality of segments are processed by a pre-trained model such that one or more labels are determined. The one or more labels are relating to one or more downhole events corresponding to each of the plurality of segments.

Abstract: A dynamic crack leaking stoppage evaluation experiment device includes a crack simulation experiment instrument having a dynamic crack simulation mechanism. The dynamic crack leaking stoppage evaluation experiment device can simulate a dynamic change process of a crack from a closed state to an open state. An experiment method can be applied to study a variation range of the width of the crack that have been subjected to self-adaptive leaking stoppage with various combinations of leaking stoppage materials and under different increments, and the method can also be applied to quantitatively study on effecting patterns of rheological parameters and hydraulic parameters of well drilling fluid on stability of a leaking stoppage layer in the dynamic crack, so that enabled is not only simulation of leaking stoppage process of a dynamic crack, but also real-time monitoring and evaluation on leaking stoppage effect and leaking stoppage location inside the dynamic crack.

Abstract: A system includes a drilling microchip, a mud return line, a magnetic sensor, and a computer system. The drilling microchip has a magnet and is configured to be pumped into the drill string and up the annulus using the drilling fluid to obtain data about the well. The mud return line is hydraulically connected to the annulus of the well and a shale shaker. The magnetic sensor is connected to the shale shaker and has a detection range. The magnetic sensor is configured to interact with the magnet to indicate a presence of the drilling microchip in the detection range. The computer system is electronically connected to the microchip detector. The magnetic sensor is configured to send a signal to the computer system upon indication of the presence of the drilling microchip.

Abstract: A jet pump for oil production involving extraction by hydraulic lift and consists of a jet pump integrally redesigned so that it is traversed by a cable for the control of the recorders of the production variables of the oil well. This control can be performed from the surface, enabling the collection of data related to measurements such as pressure, temperature and flow, both in static conditions of the well, i.e. when the well is not pumping, and in dynamic conditions, i.e. when the well is in production, and also have the security of the recovery of recorded data and measurement tools, known by its acronym MPLT (Memory Production Logging Tools), to determine the productive status of the well and make timely decisions in the management and administration of the same.
