~OUR EXPERTISE & SPECIALIZED FLEET OF EQUIPMENT SAVES YOU TIME & MONEY~
O’Keefe Drilling has established itself as a premier company drilling water wells to meet customer needs since 1959. Through its years of servicing this industry the company has built a solid expertise in determining the most optimal solution to meet your Domestic, Irrigation, Stock, Large Diameter or Public Water Supply well specifications.
At the forefront of our fleet are our two Dual Air Rotary rigs (DR-24 & DR-24 HD). The DR-24 was designed to do two things; drill large diameter boreholes through tough unconsolidated formations (sand, gravel, cobbles, and boulders) up to 30 inches and, to simultaneously case and drill in overburden formations. This design is accomplished through the use of an upper and lower drive. The upper drive works like a traditional drill rig and is used to turn the down-hole tooling. The lower drive is used to advance the casing. Both drives work independent of each other, enabling the rig to case the borehole while the drill string is being advanced, utilizing conventional Air Rotary or Reverse Circulation This makes the installation of casing faster and more accurate, while eliminating the need for under reaming or Mud Rotary.
