About David Green
Executive V.P. & CTO
David Green is a Professional Engineer with an undergraduate degree in Mechanical Engineering specializing in Fluid Dynamics. David became a partial owner of Well Master in 2004 and has helped to grow the company into a leading supplier of plunger lift technology, in part by driving and nurturing innovation, developing new approaches to engineering solutions for the challenges of unconventional wells, and partnering with customers to help them develop and train their talent. David is a named inventor on a multitude of patents relating to plunger lift and continues to advance the science around this technology. David taught on behalf of the ALRDC at their annual Deliquification Workshop and Conference from 2011 - 2016, and has been an author of SPE presentations as well as a presenter at workshops for SPE and Petro Skills. David teaches approximately 50 classes per year on Plunger Lift to a wide range of E&P companies, of which approximately 80% are repeat customers.
About Our Courses
Well Master's training and education programs are run by David Green and designed to make your training dollars more effective, improve cash flow, and maximize asset values as soon as possible. Our programs are tailored to fit the needs of the attendees and stakeholders.
Our courses address the challenges of deliquefying gas-driven wells (meaning gas wells and gassy oil wells). First, by examining the fluid mechanics of two phase flow in well piping as it applies to the wellbore. This fundamental approach provides the student a solid basis for understanding operating problems more thoroughly and thereby making more informed decisions that significantly impact production. Application of fundamental knowledge is then used to explore optimization options for plunger lift based on the life cycle of the well and well readiness. Topics include application to unconventional horizontal wells, gas lift and plunger lift combinations (GAPL/PAGL), diagnosing and solving problems. Our courses are good for all levels of operator, optimizer and engineer. Challenging, debunking, and explaining “industry standard” rules of thumb and textbook solutions can improve everyone's understanding of the options to improve well performance.
Fundamentals of Gas-Driven Unloading/Loading
Well Master’s “Fundamentals” training program is designed to explain the fundamental fluid mechanics of well loading/unloading in a way that makes it understandable at all levels. This knowledge is then used to explain in greater detail how plunger lift is used and how we can better optimize well operation.
Half day and full day options available.

Plunger Lift Training Program
This full day course combines our Fundamentals of Gas-Driven Unloading/Loading course and our Advanced Plunger Lift Concepts and Applications course. It addresses the challenges of deliquefying gas-driven wells by first explaining the fluid mechanics of two phase flow in well piping as it applies to the wellbore. Application of fundamental knowledge is then used to explore optimization options for plunger life based on the life cycle of the well and well readiness.
