About DrillHub
A free resource built because I needed these tools when I was new to the oilfield and honestly it's nice to have a fast, ad-free site to do simple calculations.
About Me
I'm a mud engineer who builds websites in my free time. I wanted to give something useful back to the people in the industry who helped me when I was starting out.
I'm not a professional web developer, but I'm learning as I go. If you see something that could be improved, please let me know. Also if you like what you see I'd love to hear it!
Why This Exists
I built this site because I needed these tools when I was new to the oilfield. Simple calculators that actually work, without the 90's looking interface, ads, or someone trying to upsell.
