Our company was established in 2002 as a private drilling fluids service company. Our organization is currently registered as an Industrial Knowledge-based company in Iran. Our primary intent and vision is to act as a services company rather merely being a supplier of drilling fluid materials. In order to be a service provider, PDF has adopted a service analogy in term of emphasizing on continuous R&D, setting ties with technology capable companies, connecting industry to academic intuitions and setting benchmarks for optimizing drilling performance. Service is the corner stone of our organization, our clients challenges are our challenges, we provide solutions and recommendations and we do not believe in short-term profit strategy.
