Machine Learning & AI
Our statistical and machine learning software is a versatile tool, capable of simulating various surface and downhole scenarios in rod pumped wells. This software serves as a training set generator, creating diverse conditions to teach a machine learning algorithm to achieve two main outcomes:

  • Generate a downhole card (green) from a surface card (blue), eliminating the need for a deviation survey or the wave equation (orange).
  • Learn and recognize different surface and pump conditions from an extensive training set of surface and downhole cards.
Step into the world of cutting-edge technology that streamlines processes and enhances understanding.

Jeff’s class is essential for any operator that is committed to continuous improvement and optimization. We send all of our production engineers, foremen, and senior lease operators to the BREX courses. Jeff’s classes have helped enhance our company’s systemic understanding of rod pumping design, analysis, and optimization. I highly recommend it.

There are only two courses related to rod pumping that I would recommend and Jeff’s is certainly one of those. He brings a passion and perspective unmatched by any of his peers that is evident to all who attend. Jeff’s experience with and explanation of the entire rod pumping system makes him one of the foremost instructors on the topic.

Jeff, Your schools are already the best offered on rod pumping; however, I admire at your continuing efforts to improve their quality.I have known Jeff for 16 years and I have attended his classes and taught with him as a team. He's a born teacher—it’s in his DNA. With his academic background and experience in rod pumping Jeff has gained superior knowledge that he enthusiastically imparts to his students. You won't go to sleep in his class.

I first met Mr. DaCunha in 2008, since that time I’ve learned the true meaning of optimization though his courses and in field training that we’ve done together over the years. With implementing his optimization methods, I’ve seen increased run time between well failure, increased production, electrical savings and significant decrease in my LOE cost. The way Mr. DaCunha breaks down the components of the rod pumping system, well analysis, dynagraph interpretation, and rod design makes it so easy to train my Lease Operators, Well Techs and Production Foreman.
