Turbopower™ Turbodrills Deliver Record Performance in First Turbine-Drilled Horizontal Well in Brazil’s ‘Pre-Salt’ Carbonates
In this deepwater well
drilled from a semi-submersible offshore Brazil, the challenge was to drill a long lateral in a very tough and hard-to-drill
formation of silicified carbonates, achieving the directional
plan while minimizing costs.
