That great achievement was a world record! Drilling with the Statoil team on the Gullfaks Alpha Platform in the North Sea, we succeeded in drilling the longest ever producing well -10,000 metres in difficult subsurface conditions.
Case study - Gulltopp well, North Sea
With the Statoil team, Seawell personnel drilled a world record length producing well from the Gullfaks fixed offshore platform
Case study 1 - Cflex tool enables annular liner squeeze despite high-loss zone
Extreme losses were anticipated when drilling a 12 ¼ inch assembly into a weak section of the formation.
Case study 2 - Cflex tool provides cementing contingency when conventional first stage fails
The first stage cementing was unsuccessful, leaving the second stage as the only option to avoid a cement top squeeze.
