Using Analytical and Artificial Intelligence Models to Estimate Drilling Rate of Penetration (ROP)

Abstract

Koorosh Tookallo, and Soheil Sohbatzadeh

Drilling a new oil or gas well to reach at reservoir involves a set of processes. Optimized drilling plan is critical to reach the target in the shortest possible time and at the lowest possible cost .Drilling plan and efficiently drilling a new well requires analysis of well data to properly determine bottom hole assembly, drilling bit, drilling fluids, and operational parameters such as weight on bit (WOB) and drill-string rotary speed. The purpose of drilling planning is to optimize the Rate of Penetration (ROP) by reducing non-productive time (NPT). In this article two different estimating drilling rate of penetration (ROP), analytical model and artificial intelligence model were described.
