Hydraulics Calculations

Basic purpose:

The Hydraulics Calculations software is intended to help in compilation of hydraulic programs of drilling. The application allows to carry out calculations and to represent its results in a graphic form. It was developed to be use in the oil and gas companies engaged to do appropriate works.

Calculations Performed:

  • pressure losses in elements of circulating system;
  • pressure losses in the annulus;
  • equivalent density of drilling fluid;
  • swabbing pressure at tool motion;
  • allowable speed of RIH/POOH of the tool;
  • bottomhole pressure while doing various well operations.

Basic Features:

    The program performs calculations by utilizing the following techniques:
  1. Bingham Plastic Model - the method described in Manuel de Rheologie des Fluides de Forage et Laitiers de Ciments (Editions Technip, 1979).
  2. Modified Bingham Plastic Model (Preston Moore) - the method described in Preston Moore's Drilling Practices Manual (PennWell Books, 1974).
  3. Power Law Model (ARTEP) - the method described in Manuel de Rheologie des Fluides de Forage et Laitiers de Ciments (Editions Technip, 1979).
  4. Modified Power Law Model (Preston Moore) - the method described in Preston Moore's Drilling Practices Manual (PennWell Books, 1974).
  5. Power Law API Model - the method recommended by the American Petroleum Institute.
  6. Alternative Model - the method represents the modern calculations approach developed by Hughes Tool Co.
