Abstract

Drilling optimization is very important during drilling operation. Optimization of drilling could save time and cost of operation thus increases the profit. Drilling optimization aims to optimize controllable variables during drilling operation such as weight on bit and bit rotation speed for obtaining optimum drilling rate. In this project, Bourgoyne and Young ROP model has been selected to study the effects of several parameters during drilling operation. Important parameters such as depth, pore pressure, equivalent circulating density, bit weight, rotary speed, bit tooth wear, and jet impact force are extracted from drilling report. In order to study their relationship statistical method which is multiple regressions analysis has been used. The penetration model for the field is constructed using the results of statistical method. In the end, the result from analysis is used to determine optimum values of weight on bit that give optimize drilling operation. Overall, this project provides a study to the most complete mathematical model for rate of penetration that was constructed by Bourgoyne and Young. From the research the constants that represented several drilling variables had been determined. The rate of penetration for the field had been predicted based on the constants for every data depth. Finally, the optimized weight on bit had been calculated for the several data points and the results had been simulated using drilling simulator.
