JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD

Prerequisites

Drilling Technology

Course Objectives:

• Knowledge of subsurface equipment below well head.
• Planning and designing of well completion after testing of the hydrocarbon zones available.
• Knowledge of subsurface circulating equipment and packers.
• Testing of multi zones in a well with DST/RFT with logging tools as well as surface testing equipment.

Course Outcomes

The student can

• Have the knowledge of various equipment used in & on wells.
• Have the knowledge of DST/RFT to know the initial potential of the wells.
• Plan and design the well completion depending of the casing policy and the number of objectives available in the well.
• Also plan for suitable safety valves in sub surface as well as on well head for the safe operation of the high pressure and high temperature wells.
• Also be a good work over engineer to repair and maintenance of a sick well.
• Be a good CTU (Coil Tubing unit) operator whenever rigs less operation are required to be taken up.
