About Us

Call it what you will, but whether you refer to it as the oilfield directory, the big yellow book, the oilpatch bible, or simply the COSSD, the Canadian Oilfield Service & Supply Directory (COSSD) remains the oil and gas directory of choice for our over 400,000* users. With more than 26,000 listings in 1,900 categories we more than double the nearest competition in qualified oil and gas industry listings.

Every year, we distribute over 70,000 copies of the digital and print editions of the COSSD. Over 50,000 copies are hand-delivered by our dedicated sales force directly to the oil and gas community, with additional distribution at 25 trade shows annually. The COSSD offers a wide range of advertising platforms, ranging from print to DVD, website to Garmin GPS, and new this year - Blackberry® and iPhone®. Ensure that you remain a supplier of choice by advertising in the COSSD, the definitive buyer's guide for Canada's oilpatch.
