Abstract
A method of automated or assisted geosteering for drilling of a horizontal well compromises automated or assisted estimation of a well's position in a target geological formation using the data acquired during the drilling process.
Claims4
A method for geosteering a portion of a well comprising:
- storing data from an original well log in a computer system configured with geosteering software and downhole sensor interfaces;
- creating a distorted well log based on the original well log by adding noise and depth distortion to the original well log, wherein the distorted well log is created synthetically to imitate a desired nearby formation;
- training a neural network based on the original well log and the distorted well log using a plurality of correlation algorithms to identify formation patterns and enhance the neural network's recognition of formation characteristics in real time;
- calculating a similarity score for each of the plurality of correlation algorithms;
- ranking the correlation algorithms based on similarity scores;
- selecting the algorithm with the highest-ranked similarity score;
- correlating the vertical and the deviated portion of a horizontal well log with a typewell log using the trained neural network;
- drilling a wellbore along a first wellbore trajectory within a deviated section of the wellbore using a downhole tool with a drill bit, with the first wellbore trajectory is having a first inclination angle and a first azimuth angle;
- sending commands, using the trained neural network, to adjust the drill bit to a second inclination angle and a second azimuth angle to change from the first wellbore trajectory to a second wellbore trajectory.
