Since 1979, Armstrong Oil Directories has published annual directories for the nation. We list companies actively involved in the production of oil and/or gas. We remain committed to the accuracy and completeness of the listings in our directories.

We contact each and every company annually to ensure the accuracy of the listings. We believe that our customers want an accurate directory with complete information and not a book that is full of advertisements, therefore, you will not find any ads in our directory. With all the mergers, acquisitions, etc we have included on the back of each directory a company cross reference section for your help. We also believe that you need to “test drive” our directory before you have to pay for it, therefore, we do not require payment prior to shipment.

All directories are sent on a two-week approval, with no obligation to buy if returned within the two weeks. If you have any questions about our directories or would like to take a look at one, please don’t hesitate to give us a call (800) 375-1838, or email us at support@armstrongoil.com.
