With a petroleum engineering degree from the University of Wyoming, Russell “RD” Evitt and his wife Lilian first came to The North Dakota Oilfield with a firm called “Core Lab” in the summer of 1957. Work was demanding for a husband and father of three boys. It was obvious that RD needed another way to provide for his growing family. With the help of a local businessman, RD purchased a Dynamometer to “weigh wells” and started what was known as Evitt Engineering.

He saw a need that was not being met in the recalibration of pressure gauges. With the use of a Dead Weight Tester, he started the calibration service first in the basement of the home and then moved to the garage. RD was self-taught, learning the business on his own and soon built his own instrument to test and calibrate the meter’s differential pressure. During the early years, RD was never favorable to having his name out front. The current name came from a costumer who upon seeing RD come in through the doorway exclaimed “Here comes Ole’ Double E!” The rest is history.
