This gas producer well in Poland was drilled overbalance in 2011 to a depth 1528 mAH. To prevent reservoir damage caused by overbalanced drilling fluids the company decided to drill the well further in underbalance mode to a depth of 1858 mAH. Snubbing was identified as the most safe and efficient method to drill underbalance into this fragile gas bearing formation.
The objective was to mobilize the Snubbing unit to Poland and to drill the well deeper to a target depth of 1858 mAH in underbalance mode.
