Abstract: System and methods of petrophysical modeling are disclosed. Measurements of formation parameters along a planned path of a wellbore are received during a current stage of a downhole operation. A correlation coefficient between each of the formation parameters and at least one target parameter for the reservoir formation is determined based on the received measurements. Input parameters are selected from among the formation parameters for a symbolic regression model, based on the correlation coefficient calculated for each formation parameter. A symbolic regression model is trained to generate a target petrophysical model, based on the selected input parameters and the corresponding measurements received from the downhole tool. One or more properties of the formation are estimated for a subsequent stage of the downhole operation, based on the generated petrophysical model. The subsequent stage is performed along the wellbore, based on the one or more estimated properties of the reservoir formation.

Abstract: Various aspects described herein relate to a machine learning based detecting of fracture hits in offset monitoring wells when designing hydraulic fracturing processes for a particular well. In one example, a computer-implemented method includes receiving a set of features for a first well proximate to a second well, the second well undergoing a hydraulic fracturing process for extraction of natural resources from underground formations; inputting the set of features into a trained neural network; and providing, as output of the trained neural network, a probability of a fracture hit at a location associated with the set of features in the first well during a given completion stage of the hydraulic fracturing process in the second well.

Abstract: This disclosure describes systems, methods, and apparatuses for preventing wireline sticking during hydraulic fracturing operations, the system comprising: a sensor coupled to a fracking wellhead, circulating fluid line, or standpipe of a well and configured to convert acoustic vibrations measured in fracking fluid in the wellhead, fluid line, or standpipe into an electrical signal in a time domain; a memory configured to store the electrical signal; a converter configured to access the electrical signal from the memory and convert the time domain electrical signal into a frequency domain spectrum; a machine-learning system configured to classify the current frequency domain spectrum as associated with increasing wireline friction, the machine-learning system trained on previous frequency domain spectra measured during previous wireline operations and previously classified by the machine-learning system; and a user interface configured to return an indication of the increasing wireline friction to an operator of the hydraulic fracturing operations.

Abstract: A communication system employed during wellbore operations, such as during drilling, cementing, fracturing, or other wellbore operations, which utilizes ultrasound (i.e., acoustic waves characterized by ultrasonic frequencies) to communicate sensor and/or control information from inside a riser and/or blowout preventer (BOP) to outside the riser/BOP, and/or vice versa. More specifically, the communication system may include an internal ultrasonic module (IUM) residing inside the riser/BOP and acoustically coupled to a drill string and/or a centralizer also inside the riser/BOP. The communication system may further include an external ultrasonic module (EUM) residing outside the riser/BOP and acoustically coupled to the riser/BOP. The ultrasound may traverse from the IUM to the EUM, and vice versa, using a communication path that may include propagation of the ultrasound through the drill string, the centralizer, and the riser/BOP without traversal through fluids contained within a fluid column enclosed by the riser/BOP.

Abstract: A setting tool is disclosed for setting an acoustic telemetry unit in tubing such as wellbore tubing. The setting tool comprises an anchor motor for driving an expandable anchor, a control unit for controlling the anchor motor, and an acoustic receiver. The control unit is arranged to determine whether an acoustic signal is successfully received by the acoustic receiver and to control the anchor motor in dependence thereon. By providing the setting tool with the acoustic receiver and determining whether an acoustic signal is successfully received by the acoustic receiver, it can be judged whether an acoustic signal from another acoustic telemetry unit in the tubing can be successfully received by the acoustic telemetry unit which is being set. This may facilitate deployment of a repeater unit at an optimum distance from another acoustic telemeter unit which is already in the tubing.

Abstract: An energy efficient protocol for a communication network made up of a network of wireless communication nodes is disclosed. To reduce the amount of energy consumed by the nodes, the nodes operate in a reduced power duty cycle acquisition mode of operation in which the nodes cycle between a low power standby state and a higher power detection state. The nodes are forced to transition out of the duty cycle acquisition mode in response to detection of a triggering event when in the detection state. The operating parameters of the reduced power duty cycle acquisition mode can be modified based on current operating conditions on the network.
