METHOD TO IDENTIFY A WATER ENCROACHMENT ZONE OR PAY ZONE TO INFORM COMPLETION AND RECOVERY OPERATIONS

Abstract: methods and systems are disclosed. the methods may include obtaining rock core data from a formation, obtaining well logs, which include a current resistivity log, from a well within the formation, and inputting the well logs into a trained machine learning (ml) model. the method further includes producing a predicted permeability log from the trained ml model, determining a rock type log based on the rock core data, and determining an initial saturation log based on the rock type log. the method still further includes predicting, using an archie-type model, an initial resistivity log based on the initial saturation log, identifying at least one of a water encroachment zone and a pay zone along the well by comparing the initial resistivity log and the current resistivity log, and designing a completion plan for the well based on the at least one of the water encroachment zone and the pay zone.
