AI Technical Summary
Technical Problem
Designing well casings for new wells is challenging and often requires expert input, leading to production delays and increased costs, and potential failures can result in significant losses and reconstruction expenses.
Method used
A method and system using a model trained on historical data and material corrosion data to generate well casing designs, selecting materials, and testing them against estimated loads, while considering inventory, pricing, and delivery constraints.
Benefits of technology
Facilitates efficient well casing design with reduced expert involvement, minimizing delays and costs, and ensuring reliable well casing performance through rigorous testing and material selection.

Abstract
A method and system for designing a well casing for a target site includes receiving an information set for the target site and generating a plurality of well casing designs for the target site. Each well casing design includes a combination of a selected materials, casing sizes, casing grades, casing weights, and lengths for a set of well casing components. The method then generates a set of estimated loads for the well casing at the target site based on historical data. The set of estimated loads including a collapse load, a burst load, a tension load, a compression load, and a triaxial load. Each of the plurality of well casing designs are tested based on the estimated loads and a list of recommended well casing designs that withstood the set of estimated loads and a higher threshold of loads is generated and a recommended well design is output.
