Directional Drilling

 

Our directional drillers have many years of experience drilling challenging wells on the North Sea and continental Europe. Having to “chase” the BHA in the softer North Sea formations to build angle or perform open hole side tracks, they keep their cool and execute the well plan. Perfect vertical well placement, horizontal step outs, simple J or S shaped well trajectories are all within our capabilities. More complicated “Pregnant lady” well designs to tap into a salt dome reservoir or avoiding faults are all scenarios that most of the directional drillers encountered multiple times.  All directional drillers carry a laptop loaded with our Wellrep™ drilling database and Landmark Compass™ software to record and plot progress, monitor anti-collision, torque and drag or perform Hydraulic calculations. Although our directional drillers have extensive experience with Rotary Steerable Systems (RSS), the bulk of their knowledge has been acquired by drilling with Positive Displacement Motors. Due to this they understand the local geology and behavior of the BHA in different formations. While monitoring rotary steerable systems are within the work scope of our directional drillers, true feeling is obtained by conventional directional drilling with PDM’s. Moving salts, swelling clays and other formation or BHA related issues could be obscured by drilling with rotary steerable systems, the feeling obtained by the more hands on approach with PDM’s is a valuable asset.
