Abstract: Directional drilling is the system of directing the well bore along some trajectory to a predetermined target. Motivation of the early drilling of directional wells was economics and offshore field development is where majority of wells are drill directionally 5 Defection Implements is: whipestock, jetting bit, mud motor, stabilizers and turbine. The Non-Rotating Adjustable Stabilizer / Directional Solution (NAS/DS) is the imitation of a mechanical process or an object by a directional drilling operation that causes a respond mathematically and graphically to data and decision to choose the best conditions compared to the previous mode. The Non–Rotating Adjustable stabilizer (NAS) can be controls curvature rate by exactly positioning and run with the optimum bit, use the most effective weight (WOB) and rotary speed (RPM) and apply all of the available hydraulic energy to the bit. The directional simulator allowed to specify the size of the curvature rate performanc!
e errors of the NAS tool and the magnitude of the random errors in the survey measurements called the Directional Solution (DS). The combination of these technologies (NAS/DS) will provide smoother bore holes, reduced drilling time, reduced drilling cost and incredible targeting precision. This simulator controls curvature rate by precisely adjusting the radial extension of stabilizer blades on a near bit Non-Rotating Stabilizer and control process corrects for the secondary effects caused by formation characteristics, bit and tool wear, and manufacturing tolerances.In this study in south of Iran the Non–Rotating Adjustable stabilizer controls curvature rate by precisely adjusting the radial extension of the stabilizer blades on a near bit Non-Rotating Stabilizer. The combination of these technologies will provide smoother bore holes, reduced drilling time, and incredible targeting precision. Implement will control curvature rates from 0 to 15/100 ft. in 8 1/2 inch holes wi!
th bit weights up to 55000 lb.
