Kick-off and Initial Build Section

Kick-off and Initial Build Section

An initial kick-off and build section with smooth build rates is required to minimise torque and drag in deeper critical hole sections.

The Drilling Supervisor should ensure all personnel are aware of this requirement and that potentially troublesome doglegs are wiped immediately.

Doglegs and Decreasing Build Rates

Excessive doglegs or a drop in build rate have a much greater effect on torque and drag in top hole than in deeper hole sections.

Extensive use of torque and drag analysis while drilling shall be made to assess . . .
