Method and system for processing well log data from multiple wells using machine learning

A system, comprising:

• a logging system coupled to a plurality of logging tools;
• a drilling system coupled to the logging system and a first wellbore;
• and a reservoir simulator comprising a computer processor, wherein the reservoir simulator is coupled to the logging system and the drilling system, the reservoir simulator comprising functionality for:
• obtaining 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 comprising the first wellbore,
• wherein the well log data comprise first acoustic data and second acoustic data that are acquired from a first wellbore and a second wellbore among the plurality of wellbores;
• generating image data regarding the geological region of interest using the well log data and a first recurrent neural network2
• 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 one or more drilling parameters for the first wellbore 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 first wellbore;
• and
• transmitting, 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 first wellbore.
