Hermes Drag Planner convinces client to run MDT in Nigeria

Petromac’s Hermes Drag Planner calculates the downhole Tool Drag coefficient of any toolstring, and when coupled with the well survey and other downhole conditions, can accurately predict to what depth it can descend to on wireline. Actual Tool Drag coefficients from the job is fed back into the Planner in order to refine it for future operations. On this particular job, the MDT was run on ultra-low friction TTB type Taxis and Hermes predicted a Tool Drag coefficient of 0.06, and a healthy head tension of 700lbs whilst descending in the 70º deviated section as shown below: Drag planning software accurately predicts downhole forces, resulting in high level of confidence and
