How often have you needed a quick way to calculate ΔP at depth based on fluid properties at surface conditions?
This simple Excel utility does the trick.
Simply enter your inputs into the yellow cells, and the worksheet calculates the pressure gradient, reported in both psi/ft and psi/m.
In addition, with interactive sliders, you can explore how key parameters impact the pressure gradient and put your intuition to the test. Think you know what happens to the oil pressure gradient when Rs increases? Try it and see for yourself!
See how the tool works in this brief demo video:

If you’d like to support the CrowdField project, two small actions make a big difference:
👉 Subscribe to the CrowdField YouTube channel, here
👉 Follow CrowdField on LinkedIn, here
That’s where I share short demos, workflows, and behind-the-scenes builds that don’t always make it into written content.
If you can spare a moment, I would really appreciate any feedback to help me refine existing products and decide what to build next.
