For more than half a century William "Bill" Briggeman has been busy drilling, completing and producing oil and gas wells. It's during this time that Bill experienced firsthand the results of using N/CO2 injected into marginally producing wells to increase production. Even though this process worked it wasn't without flaws. While in the process of perfecting this system he stumbled into and developed new technology which allowed him to thin "heavy oil".

West Texas 1980, Bill is injecting N/CO2 into a well where the oil gravity was around 22 gravity. Upon completion of N/CO2 injection he brought the well back into production and noticed that the oil had a much lighter gravity. This got Bill to thinking, if the oil's gravity can be changed below ground then why not change the oil's gravity above ground. This thought lead Bill to invent, develop and patent what's now known as Ener Gen LLC's Heavy Oil Thinning Unit.
