    Abstract: A system includes a processor and a memory. The memory includes instructions that are executable by the processor to access training data of a modern feature of interest from direct observations, remotely determined data, or a combination thereof. The instructions are also executable to compile parameter data from at least one model simulation that impacts the modern feature of interest. The instructions are executable to train a machine-learning model to generate a predictive model that matches the training data of the modern feature of interest using the compiled parameter data as input. Furthermore, the instructions are executable to predict a feature of interest in a past time period using the predictive model and at least one historical model simulation that impacts the feature of interest. Additionally, the instructions are executable to execute a processing operation for facilitating hydrocarbon exploration based on the predicted feature of interest from the predictive model.

    Abstract: A transmitter for an inground operation includes an antenna and a sensor section for generating sensor data. An antenna driver selectively drives the antenna to emit a locating signal such that the locating signal carries the sensor data. A processor controls the antenna driver to transmit the locating signal during a normal mode and to enter a sleep state that disables at least the sensor section and the antenna driver such that the locating signal is not transmitted responsive to detecting that the transmitter is inactive. The processor can enter a snooze mode from the normal mode by disabling the antenna driver so that the locating signal is not transmitted, without disabling the sensor section, and the snooze mode requires less power than the normal mode but more power than the sleep state.

    Abstract: Systems and methods for managing power at a wellsite. A system includes well construction equipment, power equipment, a power manager, power equipment sensors operable to output power equipment sensor data indicative of operational status of the power equipment, and a human-machine interface usable by a human user to enter power management settings. The power manager is operable to receive the power equipment sensor data and receive the power management settings, wherein each power management setting is associated with a corresponding mode of operation of the power manager. The power manager is further operable to, for each power management setting, change the mode of operation of the power manager to the mode of operation associated with that power management setting, and for each mode of operation, cause the power equipment to supply electrical power to the well construction equipment in a predetermined manner with respect to that mode of operation.

    Abstract: A crude oil lifting system that uses pneumatic and/or hydraulic sources to control vertical operations of a downhole pipe. The lifting system may have a plurality of lifting actuators, a plurality of alignment actuators, and a guiding system. A plurality of hydraulic cylinders may be coupled to an attachment platform that is coupled to a sucker rod. Pressurization and de-pressurization of the hydraulic cylinders causes repeated vertical movement of the sucker rod, thereby retrieving oil or gas from a downhole well. A control system may selectively and individually actuate each hydraulic cylinder and/or pneumatic cylinder based on measurements provided by a plurality of telemetry and/or position sensors. A plurality of permanent or electromagnetic magnets may be utilized to assist in vertical movements of the attachment platform, and a plurality of DC generators may be utilized to generate power from the vertical movement.

    Abstract: A method may include determining an action associated with field development planning or asset management of an oilfield based on a policy or value function and a state, simulating a reward of the action using information identifying the action and the state as inputs, generating an experience record based on executing the simulation, wherein the experience record identifies the simulated reward associated with the action and a current state or resulting state, storing the experience record in an experience buffer, wherein the experience buffer stores a plurality of previously generated experience records, updating the policy or value function based on the information stored in the experience buffer, selecting an action related to the field development planning based on the updated policy, and displaying information representing the action.

    Abstract: A method may include receiving a digital well plan that specifies planned drilling parameters for drilling a borehole, where each of the specified planned drilling parameters includes one or more of a minimum threshold and a maximum threshold; generating statistical distributions of actual drilling parameters in real-time responsive to receipt of real-time data acquired during a depth-based window for the drilling; generating comparisons in real-time, where each of the comparisons is between one of the statistical distributions and a corresponding one of the planned drilling parameters for the depth-based window; and, responsive to one or more of the comparisons indicating an unacceptable actual to planned parameter deviation, issuing a control signal.
