About The Company

Chuck Ellison

In 1980, Ellison Fluid Calipers was started by Chuck Ellison in Odessa, TX. Chuck has a M.S. in Geology/Geophysics.  He has over 40 years of experience in the oilfield and has over 35 years’ experience in fluid dynamics.  During Chuck’s study of fluid dynamics he was able to perfect the fluid caliper by cross correlating 6 different factors; Hole size and Pump Volume, Viscosity and Density, Rotary Speed and Hole Load.  To this day, Ellison Fluid Calipers is the only company to do so.   With ten’s of thousands of fluid calipers run, we have accumulated a client list of 250+ oil companies, both majors and independents.
