Abstract: The industry of drilling for oil, gas geothermal, and storage purposes necessitates construction of challenging wells in recent applications. Challenging wells are required to be designed prior to the drilling to selection of the equipment to be utilised while drilling. A poor engineering planning may result in losing time and effort to remediate torque and drag related troubles which might be encountered. Adequate planning is significantly important which is going to reveal possible drawbacks in planned well prior to commencing operations. The drag and torque calculations are required to be estimated and monitored accordingly whilst drilling of the wells. This paper gives the details of torque and drag calculations for every one-metre interval, so that the rig crew can see what is the theoretical calculated magnitudes and compare them to the actual. Implementation of this study is going to identify limitations due to torque and drag allowing safe drilling. [Received: April 6, 2016; Accepted: September 20, 2016]
