Engineering disclaimer

PetroQube provides educational and preliminary-estimation calculators. Results are generated from user-supplied inputs and simplified equations. They are not certified engineering outputs, operating instructions, or professional advice.

Verify before use

• Independently verify all equations, units, input values, assumptions, and results.
• Do not use these tools as the sole basis for well control, drilling hydraulics, casing/cementing programs, reservoir management, reserves reporting, or safety-critical decisions.
• Real wells may require validated models accounting for geometry, temperature, pressure, rheology, multiphase flow, uncertainty, and local operating standards.
• Recovery-factor outputs are scenario estimates and are not reserves bookings or economic forecasts.
• PetroQube makes no warranty that a calculation is complete, accurate, suitable, or fit for a particular purpose. Qualified engineers remain responsible for engineering decisions.

By using the site, you acknowledge these limitations and agree to independently assess whether a tool is appropriate for your application.
