An offshore operator drilling exploratory wells experienced high torque, lost
circulation and hole collapse during drilling operations for the XUX-1 well. Cement
plugs were placed across the thief zone, but lost circulation ultimately increased
drilling days and total well cost. The operator began drilling operations for a new
well, KAA-1 and wanted to reduce costs compared to the XUX-1 well.
Working with Impact, the operator added FLC 2000® wellbore stabilizer to the
drilling program in the offset well, KAA-1. FLC 2000 was added to reduce fluid
loss, prevent lost circulation and total well costs.
During the 26-day drilling stage on the original XUX-1 well, 12.5 days were used
fighting lost circulation and placing cement plugs. On the KAA-1, where FLC 2000
was added, there were no fluid loss and the operator reduced NPT and total well
costs by completing the section in 10 days.
