28” EVEREST® 113





Customer Challenge

The Customer focused on drilling the complete 28” vertical section in using one Mill Tooth RC bit run while achieving the best possible ROP and lowest cost per foot.

The previous top 5 wells in the same field using Mill Tooth RC bit design achieving 49.7 ft/h ROP average across the field.

Record run in the area was set @ 70.8 ft/h.

Varel Solution

VAREL proposed a Mill Tooth RC design leveraging the EVEREST® technology. EVEREST® bit series designed as solution drill bit for any type of well profile that is especially suited for surface and intermediate hole sections.
