DRILTEK is responsible for the successful completion of thousands of well operations – many at depths of between 12,000 and 21,000 feet – both in California and around the world. Our experience spans across a multitude of activities, which includes urban development, pad drilling, and deep horizontal targets.

Just some of our California key accomplishments include:

  • Successfully killing the 1998 Lost Hills’ Bellevue #1, the highest-pressure blow out in California history
  • Running first ever economic polycrystalline diamond compact (PDC) bit in California
  • First permanent packer whipstocks to sidetrack deep wellbores in the Southern San Joaquin Basin
  • Macpherson Oil Company (Round Mountain Horizontal Development Program)
  • Berry Petroleum (Midway Sunset, Placerita)
  • Seneco Resources Corporation (Midway Sunset, Lost Hills, Sespe)
