Paper Title:
Optimum Placement of Friction Reducer in Extended Reach Well
  Abstract

There are some problems such as down hole torque & drag, casing wear and so on in extended reach drilling. Therefore, friction reducers are used widely to keep the drillstring away from the cased hole in extended reach drilling. Currently, the optimum placement of friction reducers is dependent on the drillstring deflection. Friction reducers are often connected to drill pipes by tool joints, which limits their optimum placement. In addition, the placement of the first reducer is often determined by drilling engineers’ experience. The effect of friction reducer on torque & drag is assessed in this paper and the optimum placement of friction reducer is obtained to minimize the torque & drag.
