Engineering module

Drilling hydraulics

Enter the mud rheology, drill string, hole program and bit; the software computes the full pressure picture of the well, before and during the run.

What it computes

Key outputs

  • SPP breakdown — surface equipment, string, downhole tools, bit, annulus
  • Bit hydraulics: pressure drop, jet velocity, HHP / HSI, impact force
  • ECD vs depth
  • Annular velocities, hole cleaning and maximum flow guidance
  • Flow rate sensitivity and bit nozzle optimisation per depth
  • Full PDF report
Standpipe pressure against flow rate, with bit hydraulics optimisation and ECD against depth
Standpipe pressure against flow rate, bit hydraulics optimisation, and ECD versus depth.

Inputs and saved sessions

Fluid, wellbore, string and bit, and operating parameters are entered under four tabs. Multiple rheology models included. Cases are saved as named sessions with their results and reloaded later, available for all modules.
