Snubbing

Live well intervention

Profitability in today's oilfield relies on peak production. Snubbing units can perform operations safely and efficiently on live wells. No kill fluids and minimal, if any, formation damage all add up to peak production for your well. Well Intervention snubbing units are ideal for many types of drilling and workover applications. Best suited for side-tracking and deepening existing wellbores, these  units have many advantages over more conventional drilling methods in many situations. The ability to pull existing completions, drill open holes and re-complete the wellbore at near balanced, underbalanced or flowing conditions, allows our units to bridge the technological gap between derrick equipment sets and coiled tubing units. In those drilling operations where kill-weight fluids are unsuitable, these units offer a safe solution by providing the operator the safety factors required to compensate for unknowns in safety sensitive operations.

Equipment

Snubbing units are giving you the technical capability to install or remove tubular from a well, while the well remains pressurized. This technique is used when it is not possible or not desired to kill a well. Killing a well means depressurize the well by pumping a heavy fluid or mud inside the well. The advantage of such a live-well intervention is that work can be performed without killing the well thus eliminating reservoir formation impairment or costly stimulation operations. Before starting a snubbing operation, dedicated engineering is required; a detailed program with contingencies must be in place to ensure that operations on live wells can be performed safely. Our specialists gained their experience while dealing with multiple complicated live-well scenario’s around the globe over the last decades what would make them a valuable asset to your team.
