Directional and horizontal drilling have now become an essential element in oilfield development, both in onshore and offshore operations. There are several types of deflection tools; the most common of which are downhole motors (PDM) and rotary steerable system (RSS). A rotary steerable system (RSS) employs specialized downhole equipment to replace mud motors. A rotary steerable system (RSS) is able to make continuous changes in inclination and azimuth without interrupting drilling operations. It produces a cleaner and smoother wellbore while reducing drag, improving the transfer of weight on bit and increasing the rate of penetration. The RSS system offers the potential to drill safe and faster sections due to the fact that no time is wasted in orienting the toolface prior to drilling especially in extended reach drilling where tool orientation is particularly difficult. There are many challenges to drill a directional well compared to a vertical well, such as limitation in weight on bit, hole cleaning, trajectory control, etc., this lead to difficult selection to the proper parameters to increase the rate of penetration. Prediction of ROP is necessary for planning and cost estimation. ROP depends mainly on operational variables and formation types
