Abstract: Drilling optimization is very important during drilling operation, to save time and reduce 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 maximum drilling rate. In this study had been selected the effects of several parameters during drilling operation. Important parameters such as depth, density, bit weight, rotary speed per minute, efficiently cuttings transported hole is to take into account the factors given in Table 3. It was concluded that average annular fluid velocity is between 414.17 to 581.24ft/min, dominating parameter on cuttings transport, the higher the flow rate. s Another important factor is the mainly the rheological properties of the drilling fluid such as Vis=45-50 s, p.v=12, PH=10, mud weight is between 8.57 ppg to 8.74 ppg. The rate of penetration for the field data had been calculated for several data points. Although the weight on bit has increase from 6600 until 19800 lbs, 1137.41 lbs/in, rate of penetration still in the range of 11.74 ft/hr. The optimized bit weight is 13200 lbs or 1077.55 lbs/in during drilling operation, penetration rate for depth 4330.02 ft is suitable due to formation that is may be high in strength.

Abstract: The objective of the present work is to optimize drilling parameters such as WOB, ROP, RPM, flow rate and drill diameter of hole. The research contribution to investigation and analysis field data. This paper focuses on the optimization of drilling parameters. Drilling optimization is very important during drilling operation, to save time and cost of operation thus increases the profit. The result from analysis is used to determine optimum, RPM, ROP, flow rate, to give optimum drilling performance. Optimization the drilling parameters for depth at 11778.79 ft, weight on bit between 33000 lbs to 44000 lbs and rotary speed range between 50 to 80 rotation per minute, flow rate is 356.67 gallon /min, Optimize value of weight on bit per inch diameter of bit 8 1/2" in range 3882.35 lbs /in to 5176..47 lbs/in, The productive time for drilling is 60.5%. from total time of operations.
