1. A method, comprising:
obtaining, by a computer processor, well log data regarding a geological region of interest, wherein the well log data corresponds to logging-while-drilling (LWD) measurements or measurement-while-drilling (MWD) measurements acquired from a plurality of wellbores,
wherein the well log data comprise first acoustic data and second acoustic data that are acquired simultaneously from a first wellbore and a second wellbore among the plurality of wellbores;
generating, by the computer processor, image data regarding the geological region of interest using the well log data and a first recurrent neural network,
wherein the image data describes an interwell region within the geological region of interest,
wherein the first recurrent neural network filters interference from the first acoustic data and the second acoustic data to produce adjusted well log data;
determining, using a second recurrent neural network and a reinforcement learning algorithm, one or more logging parameters based on the well log data acquired from the plurality of wellbores; and
adjusting, based on the adjusted well log data and using a command, one or more logging parameters regarding a logging tool that generates a subset of the well log data in the wellbore,
wherein the one or more logging parameters comprise an amplitude, a frequency, or a phase shift of an electrical sensing signal that is produced by the logging tool, and
determining, by the computer processor, one or more drilling parameters for a wellbore among the plurality of wellbores in real-time using the image data,
wherein the one or more drilling parameters are determined while the well log data is being acquired in the wellbore; and
transmitting, by the computer processor and based on the one or more drilling parameters and/or the one or more logging parameters, a command to a drilling system and/or a logging system coupled to the wellbore.
