Drilling and Workover Hydraulics

Competency Statement:

Maximize penetration rates, minimize formation damage and ensure hole stability through the proper application of drilling hydraulics principles.

Learning Objective:

Upon completion of this module, the participant should be able to
  • determine the pressure losses that occur in the rig circulating system
  • use basic calculation methods to determine optimal bit nozzle size, annular velocity and other rig hydraulics parameters
  • diagnose drilling problems resulting from poor hydraulics practices

Assignment Instruction:

The objective of a drilling hydraulics program is to maximize bit life and penetration rate by efficiently removing drilled cuttings and by cleaning, cooling and lubricating the bit and drill string. The key to a sucessful hydraulic program is to deliver an optimal amount of energy to the bit.

The easiest way to control and optimize drilling hydraulics is to select the appropriate bit nozzle diameters for delivering the maximum amount of hydraulic energy to the bottom of the hole.

In assignment, you will learn to use drilling hydraulics principles to maximize penetration rates, ensure hole stability, optimize hole cleaning characteristics and minimize formation damage.

By the time you complete this module, you should be able to determine pressure losses in the rig circulating system and select the appropriate bit nozzle diameters for optimizing hydraulic energy.
