| Rotational drilling was a revolution in drilling technology. It made the drilling process more efficient and faster and more depth of well could be achieved through rotation method. Besides all of its advantages, the rotation approach induced some problems like pipe sticking and downhole cleaning to the drilling procedure. Hole cleaning and reduction of torque and drag seems to be vital in inclined and horizontal ones due to its complexity and inclination. In this manuscript, hydraulic, torque and drag analysis were surveyed to investigate whether the path proposed for a well in the south of Iran is adequate or not. The required information was provided from associated drilling company and the proposed well trajectory used with hydraulic and drag data to run simulations via drilling office software. Effective axial load, Interaction of well and drill string, Comparison of stresses and von Mises graph were reported. Mentioned graphs showed the consistency of drilling project. The sensitivity of pressure drop to the pump flow rate and critical required rate to clean up annulus also reported pressure drop through the drilling system and required flow rate to clean up the bottom hole. In another word, obtained results of drag and hydraulic showed the consistency of trajectory. | ||
