The use of turbodrills and polycrystalline diamond compact (PDC) bits with an innovative, tracking cutting structure has improved drilling economics in medium and hard formations in the Gulf of Mexico. Field results have confirmed that turbodrilling with trackset PDC bits reduced drilling costs, compared to offset wells. The combination of turbodrills and trackset bits has been used successfully in a broad range of applications and with various drilling parameters. Formations ranging from medium shales to hard, abrasive sands have been successfully and economically drilled. The tools have been used in both water-based and oil-based muds. Additionally, the turbo-drill and trackset PDC bit combination has been stable on directional drilling applications. The locking effect of the cutting structure helps keep the bit on course.
