From Oil and Gas Fluid Gravities to Reservoir Pressure Gradients

Need a quick way to calculate ΔP at depth based on surface fluid properties?

‍

This simple Excel utility does the trick. Just enter your inputs into the yellow cells, and it calculates the pressure gradient in both psi/ft and psi/m.

‍

Plus, with interactive sliders, you can explore how key parameters affect the gradient and test your intuition—think you know what happens to the oil pressure gradient when Rs increases? Try it and find out!
