Downhole Diagnostic:

Founded in 2014, Downhole Diagnostic LLC is a Midland, Texas, based business that focuses on Well Optimization & fostering Well-Being.  Using easily installed surface-mounted equipment (a Fluid Level Gun + Dyno), we acquire downhole producing data to help oil operators monitor, troubleshoot, and optimize their producing wells.  


We perform service for companies all around the Permian Basin (West Texas & New Mexico) as well as making occasional trips out to the Eagle Ford and other producing regions.


[NOTE:  I am Downhole Diagnostic's only employeeso you can expect the same quality of service each and every job. Since I am the only employee, if you see the term "we" written anywhere on the website just know the term is referring to me and the Dyno King!  (...sometimes saying "we" makes me more relaxed knowing I am not the only one burdening all the weight around here) ]


In addition to performing Fluid Level & Dynamometer Surveys with the end goal being being Rod Pumping Optimization, we also perform Failure Analysis Studies, provide in-house and/or field-based Rod Pumping Training Courses (for engineers, pumpers, or fellow Well Techs) and we sometimes still do a little Company Man work Supervising Pulling Units.


Downhole Diagnostic is represented by our mascot, the Dyno King (AKA “the Downhole Dyno”).

Shawn Dawsey:

Raised in San Antonio, TX, I attended Texas A&M and graduated with a Bachelor's degree in Petroleum Engineering and a minor in Geology in 2009.   I then moved to Midland, TX, where I worked for a well-established, smaller-sized Oil & Gas Operator as a general Petroleum Engineer.  I was driven to succeed and inspired to learn, so I quickly took an interest in Rod Pumping design, optimization and failure prevention, and I quickly began to apply what I was learning at my job with great success.


In April, 2012, I was promoted to the position of Production Manager, which I held for 2-years until I departed in May, 2014, to erect Downhole Diagnostic. 


My work experience with my former employer included: 

  • Acting as the Company Man: supervising drilling rigs and pulling units.
  • Direct interaction with Pumpers troubleshooting surface equipment and downhole pumping problems.
  • Writing procedures for well workovers, cement squeeze jobs, & completion drill-outsthen supervising the field work.
  • Monitoring well tests, lease production, and LOE (Lease Operating Expenses).
  • Performing root-cause failure analysis (on-site and through Well File reviews) & optimizing downhole equipment designs.
  • Monitoring, revamping, and directing the chemical program and the hot oil program.
  • Acquiring diagnostic data on rod pumping wells, applying the information by making changes to the well, and then monitoring the result.


While working for my former employer, I took a special interest in Rod Pumping Optimization and Failure Prevention.  By implementing new downhole equipment designs, revamping the chemical treating program, and working with the field hands to educate and optimize the field operationsI helped spearhead an average 40% reduction in the failure frequency during my 5-year tenure with the company.


In December, 2014, I became a licensed Professional Engineer in the State of Texas after passing the Professional Engineering Examination.

But more importantly—on a personal level—I have a passionate zeal for living life to the fullest!  I enjoy the challenge of running Marathons (personal best of 3:11:27); I am passionate about reading, learning, and philosophizing on the deeper matters of the life; I think growth only comes from hard work and pushing limits—hence, I work harder than a Mexican donkey.  (I thought working for myself was going to be the best thing ever!...then I figured out who my boss was...)
