POTENTIAL APPLICATION OF COILED TUBING DRILLING IN MALAY BASIN

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.
