Torque, Drag & Hydraulics

Well engineering course that introduces Torque & Drag and Hydraulics to drilling and completion planning and operations engineers, comprehensively covering fundamentals, industry best practice and what if analysis. The three day course is delivered with hands-on training using industry leading commercial software (WellPlan) and with real life well examples.
