Abstract
The need for oil in the world is quite varied, ranging from cooking needs, factory fuel, to motor vehicle fuel. To obtain oil reserves, it is necessary to drill from the surface to the reservoir. The type of drilling used in this study is directional drilling, where the drill hole is deflected a few degrees and then directed to the target formation which is not located vertically under the well. Planning in directional drilling includes the planning of the drilling path and planning for the composition of the BHA that will be used during the directional drilling process. The process carried out to determine the evaluation points for inclination and Azimuth in AMR-10 wells is by making drilling trajectory planning using the radius of curvature method, then comparing the results of the planning trajectory with the actual trajectory calculated using the minimum of curvature method by calculating the value of true vertical depth, build-up rate, azimuth direction radius, dogleg severity, ratio factor, northing and easting, and horizontal displacement. Based on the calculation results of the AMR-10 well trajectory planning, a vertical final depth value is at 6540.9 ft, and horizontal displacement from the starting point of drilling is 2290.3 ft with an azimuth angle of 202.68 °. Based on the survey data calculation results, it can be seen that an inclination angle of 1.76 ° has occurred at a depth of 149.2 ftMD and azimuth angle of 206.6 ° at the same depth.
