Letting Experience and Wisdom Lead


Tres Management Corporation was founded in 1992  by Al Doty, Stan Dobler and Brad Crouch to provide engineering, project management, contract operating and field supervision services in the Continental US. 

Though we’ve grown since our founding, we’re still the same agency at heart. The founder's vision of providing steadfast engineering practices with integrity, and our client's best interests in mind carries on.


Today Tres is managed by Jason Goss and Luke Riggins with the same mindset of providing topnotch service with all lines of business.

Before joining Tres Management, Jason held multiple engineering roles for both small and large independent operators including Blue Dolphin Production and Devon Energy. He has experience in all major basins across the US.

Since starting with Tres in 2011, Jason has continued to build on an impressive resume adding multiple operating areas and greater diversified experience. Jason has extensive experience in managing gas storage operations across the US, designed and managed water-floods, horizontal drilling and completions technologies.

Jason has a bachelors in Petroleum Engineering from Oklahoma University and is a registered Professional Engineer for the state of Oklahoma.

Growing up on a farm, Jason brought that hard work ethic as well a passion for hunting into the office. When not working Jason spends his time with wife and daughter in Yukon.
