About Us

Our story stems from H. Ozcan Sinag’s deep efforts to perform his vision of spare-part manufacturing plant in southern Anatolia. He did so, by founding YEPA Ltd. Sti. in 1966 and raising the company’s recognition to an international level in the decades that followed. In 1995 an affiliate ILMER Dokum Ltd.Sti. metal-casting plant was established to act as an internal supplier. Together they offered “from design to end-product” solutions.

Based on this backbone, years of unique and sensitive work to find industrial solutions to the sectors including Mining, Oil & Gas Drilling and Energy generation yielded the first R&D Project of ”An Alternative Approach to locate possible Hydrocarbon fields” in 2003.

In order to turn years of studies into practice, BERDEN Maden Petrol A.Ş. has commenced its journey in 2018 with best wishes. Our corporation keeps the pledge of hardwork and is dedicated to serving world-citizens’ welfare through bringing underground bounties into daylight.
