Abstract: A method may include obtaining well log data regarding a geological region of interest. The well log data may correspond to logging-while-drilling (LWD) measurements or measurement-while-drilling (MWD) measurements acquired from various wellbores. The method may further include generating image data regarding the geological region of interest using the well log data and a recurrent neural network. The method may further include determining a drilling parameter for a wellbore among the wellbores in real-time using the image data. The drilling parameter may be determined while the well log data is being acquired in the wellbore. The method may further include transmitting, based on the drilling parameter, a command to a drilling system coupled to the wellbore.

Abstract: A tubing string is disposed within a wellbore to be in fluid communication with a reservoir. One or more inflow control devices are provided in the tubing string to receive well fluids produced from the reservoir. The one or more inflow control devices include a chamber in fluid communion with the tubing string. An inflow control valve is disposed in the chamber. The inflow control valve is configured to regulate a flow of the well fluids entering the tubing string based on a ratio of hydrocarbons to water. A control system is coupled to the inflow control valve. A plurality of sensors is on the tubing string and in communication with the control system to measure well data within the wellbore. The control system receives the well data to create commands to adjust a valve state of the inflow control valve corresponding with a required production rate of a well.

Abstract: Systems and methods for geosteering using reconciled subsurface physical parameters are disclosed. The methods include obtaining reconciled physical parameters at each of a plurality of locations within a subsurface; training at least one machine learning network to classify the reconciled physical parameters into a rock type based, at least in part, on the reconciled physical parameters; classifying the reconciled physical parameters into the rock type with the at least one machine learning network; and interpreting the rock type to form a subsurface geology model and inform a geosteering decision.

Abstract: A system for drilling a wellbore is disclosed. The injection pump releases the taggant into the mud stream traveling downhole. The taggant attaches to the rock cuttings and it is detected on the surface by the taggant detector. The taggant detector provides the data relating to the taggants detected in the drilling fluid. The data is analyzed by taggant analysis and control engine, which produces an injection profile. Based on the injection profile, the IoT Controller adapts the parameters of the taggant injection pump to achieve a real-time optimization of the taggant injection.
