From new facilities and customized equipment to capacity expansions and operational improvements, DOCo helps midstream operators move projects forward with confidence. Our Gas Plant Nerds™ provide engineering, design, equipment, fabrication, and field installation support built around how gas plants are actually constructed and operated.
A successful gas processing project must do more than meet the process conditions. It must fit the site, support operations, remain constructible, and make commercial sense.
That is where DOCo’s Gas Plant Nerds™ bring value. We combine decades of natural gas processing experience with multidisciplinary engineering, equipment knowledge, and field execution support to develop solutions tailored to each customer’s priorities.

The Gas Plant Nerds are the engineers, designers, equipment specialists, project professionals, procurement experts, quality personnel, and field-support team behind Derrick Oneal Company’s natural gas processing solutions.
We understand that the right solution is not always the most complicated one. It is the one that meets the process requirements, works within the available footprint, supports the operators, and can be executed successfully.
Because Every Great Gas Plant Starts With Great Nerds.

From high-capacity treating facilities and new refrigeration equipment to capacity studies and creative brownfield solutions, DOCo helps customers get more from their gas processing assets.
