Jordan Mimoun

Well Testing Team Lead ExxonMobil

Jordan Mimoun, SPE, is a reservoir engineering subject-matter expert and well testing team lead at ExxonMobil. He and his team oversee ExxonMobil’s worldwide exploration and appraisal testing (including design and planning, onsite operations supervision, and data interpretation and integration), while supporting pressure transient analysis for producing assets. Mimoun recently served on the steering committees of the SPE Applied Technology Workshops on well testing, as chairperson in 2017 and session chair in 2014. He is the ExxonMobil representative to WinCubed’s Welltesting Network. Mimoun holds an MS degree in petroleum engineering from The University of Texas at Austin and a diplôme d’ingénieur degree from École Centrale de Lille, France.

  • The subsurface is complex enough that multiple assumptions and hypotheses remain plausible; not all information may fit the storyline, and some might be dismissed or underweighted before the full range of possibilities is considered. A critical component of interpretation includes acknowledging one’s own bias and carefully listening to and seriously considering altern…
  • Most of today’s equipment and interpretation methods are indeed not new. After all, well testing has been around for nearly a century, resulting in a legacy that may not always look cutting-edge, but these tried-and-true tools were so technologically remarkable that they became staples.
  • In my inaugural column as editor of the Well Testing Technology Focus feature, I want to shine a light on the notable trend among operators of seizing on the tremendous untapped potential that exploration and appraisal wells represent for far-field reservoir characterization and connectivity.
