PF-05 <br /> x <br /> cos(86°) = 50 <br /> x = 3.49 75 ft Soil depth: <br /> cos(89°) = 75 12" <br /> y = 1.31 -4/ <br /> x +y = 4.80 <br /> d = V752 + 502 <br /> d = 90.14 - 50ft Pad orientation: <br /> 4.80 <br /> sin 0 = 116° <br /> 90.14 <br /> 0 = 3.05 <br /> Since the topographic gradients of all five drill pads are less than 5° (4.44°, 2.63°, 1.34°, 2.00°, <br /> and 3.05°),the drill rig will be able to be self-stabilized utilizing the built-in hydraulic lift system <br /> without having to reshape the topography. <br />
