Simultaneous hole enlargement with rotary steerable systems is becoming a common drilling application in offshore and deep offshore wells
While the reasons for hole enlargement might be different in each case, the challenges of determining the best tools for the application are common. As compared to conventional rotary steerable systems, drilling efficiency in simultaneous under-reaming operations might be lost because:
BHA component reliability is generally reduced
BHA vibration levels are increased while drilling and reaming
Hole cleaning while tripping out takes longer and it is more difficult
While drilling the casing shoe, drilling parameters are restricted to avoid under reamer involuntary activation
While drilling and reaming, enlarged hole gauge on drilling parameters, formation drilled, and directional work performed
Our hole enlargement products and services are engineered to help solve these problems and restore efficiency in your drilling operation.
