Water Wells Hole Opener Operational Considerations
Drilling Weight - The choice of drilling weight is determined based on the recommendations of the bit manufacturer and the number of cutters on the hole opener.
Number of Cutters - The number of cutters placed on a hole opener is governed by the following facts:

  • Maximum number which will fit around the perimeter.
  • The greater the number of cutters, the less the weight, which therefore reduces the penetration rate.
  • In softer formations, less weight is needed to penetrate.
  • The greater the number of cutters, the smoother the tool will run.
  • The greater the number of cutters, the greater the cost.
  • The greater the number of cutters, the longer the cutters will last
Rotary Speed - Maximum speed is determined by the manufacturer's recommendation and the calculation to account for the linear distance the cutter is moving per revolution.

Hole Cleaning - A frequently over looked point of hole opener operation is hole cleaning. The volume of cuttings to remove from a hole increase by a squared factor with an increase in hole diameter.
