Abstract: This project deals with the entire new concept of Snake Wells. What are they, Why were they drilled, Where were they drilled, What was the technology used, What were the problems, How were they mitigated are some questions answered in this project. This project report also covers some of the basic Horizontal Wells technology literature including Dog Leg Severity, Hole Cleaning, Mud Systems and ECD management. The questions answered are based on the research done of the entire free resources available on Internet. Analysing was done on the facts and figures crossed through the literature and possible solutions are suggested are suggested at the end. Analysing the literature revealed that these type of wells are limited only to a particular type of stratigraphy in the reservoir (high dipping multi-layered thin reservoirs). Also, the literature revealed that a no. of “Drilling Complications” are faced by these wells like Hole Cleaning, Shale Instability and BHA design. Literature Research for the different phases of completions adopted for snake wells was also done. The first phase used DTS (Distributed Temperature Sensor). The second phase used ICVs (Internal Control Valves), Pressure Downhole Gauges (PDHG). Second phase still had problems of Torque and Drag, hence in the third phase, diameters of tubing and liner were reduced.
