Challenge: Directionally drill a lateral
greater than 4,000 ft with a capability that exceeds the performance of
directional assemblies using polycrystalline diamond compact (PDC) or roller
cone bits on positive displacement motors (PDM).
Solution: Run a 4 3/4-in T1XL MK1 Neyrfor
Delta high-performance turbodrilling system with a 1.5° double bend and
Smith Bits Kinetic 6 1/8-in K505 impregnated diamond bit.
Results:The 6 1/8-in 4,040 ft lateral was
drilled in single-run time of 589 h, saving 8 days and USD 335,000.
