Core Values

What Our Consultants Say

The Petrostream Business Development Staff secured a consulting position for me with a major oil company, and their Administrative Staff facilitated the on-boarding and billing process with the client. All invoices were promptly paid with accurate tax records in January the following year. Petrostream provided professional, 100% support throughout the assignment.

Dave Mouton

Petrostream has provided me with two excellent project opportunities, one in the U.S. and one international. Both projects allowed me to use my existing skills but also allowed me to expand my experience base.
