Performance By The Numbers

Magnus® Rotary Steerable System

Quadruples ROP and Achieves TD in Challenging Well

Objectives

  • Finish drilling a well in a challenging basin. The operator had been unable to finish drilling the lateral in a well using a conventional motor assembly.

Our Approach

  • The Weatherford team recommended the Magnus rotary steerable system (RSS) for its high-performance drilling and precise directional control capabilities.
  • Without the need for a reamer run and with minimal reaming, the team tripped the 8.5-in. Magnus RSS bottomhole assembly (BHA) to bottom through a motor-drilled hole.
  • The Magnus RSS BHA achieved a rate of penetration (ROP) four times that of the motor BHA and drilled a total of 3,069 ft (935.4 m).
  • The RSS reached total depth (TD) in the lateral section without requiring any agitators, expensive antistick-slip tools, or torque-reduction tools in the BHA.
  • After reaching TD, the team tripped the Magnus BHA out of the hole with minimal backreaming or overpull.

Value to Customer

  • The Weatherford Magnus RSS enabled the operator to quadruple the ROP compared to a conventional motor assembly and finish drilling the lateral section in a 4.5-mile (7.2-km) well to TD.
