Coiled Tubing Drilling (CTD) is a niche technology developed in continuous effort to recover hydrocarbon from subsurface. It had been applied around the world and show significant advantages compare to the conventional drilling. One of the significant advantages is increase in the rate of penetration (ROP) which is higher compare to the conventional one. In this project, Bourgoyne and Young ROP model have 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 conventional and CTD wellare constructed using the results of statistical method. In the end, the result from analysis being compared to determine the CTD advantage over the conventional well in term of higher rate of penetration value. Overall, this project provides a study to the most complete mathematical model for rate of penetration that was constructed by Bourgoyne and Young. The model had been chose before other existed model. Using the Bourgoyne and Young model, CTD ROP is calculated. Several assumptions have been made. The ROP value we get from the model show us the potential of CTD to be applied in Malay Basin. v
