Challenge: Reduce the number of attempts
needed to place kickoff plugs in highly deviated wellbores where slurries are
pumped at underdisplacement volumes and mud contamination risk is high.
Solution: Use PlugAdvisor cementing plug
placement design software to optimize displacement volumes, mud removal, and
plug location; pump a viscous reactive pill to keep plug in position; and
establish best practices to exploit experience of the operator and
Schlumberger.
Results: Set kickoff plugs on first attempts
for Wells 1 and 2. Accurately predicted top of uncontaminated cement above Well
2 plug.
