Introduction to Drilling with Casing Technology

Course Description

This fundamental course begins with an introduction to the DwC industry, key benefits of the technology, and the primary DwC systems employed by various operators. This is followed by selection of equipment for setting up a competent DwC system comprising of surface casing drive and handling equipment and downhole components. Various engineering calculations will also be discussed. At the end of the course students will be given an assessment test.


  • Drillability analysis, drill bit knowledge
  • Bit record and dull grading, basic log interpretation, and drilling exponent
  • Casing drill bit and casing drives
  • DwC Operations and economics,
  • Hydraulics, torque and drag analysis, cementing, and drilling with liner
