After joining the group of knowledge-based companies, Derkavsh Technical Engineering Company has started its cooperation with research and academic centers.
After the implementation of the first fully hydraulic drilling machine construction project in Iran, we are now looking at future issues. This is not possible without having technological ideas and solutions that are of great importance to the company’s business goals.

While consolidating our position in Iran, our goal is clear: We intend to expand our activities in West Asia and then in scale, and we are steadfast in our path. So far, more than 4 research projects have been carried out in the field of non-oil exploration to improve the quality of drilling mud and increase efficiency. Also, one of the problems of the country’s drilling industry in bypassing the sanctions was completely solved by designing and manufacturing drilling machines at Darkaush Technical Engineering Company.

In this regard, the research and development unit of Derkavsh Technical Engineering Company was established with the aim of meeting the needs of the company in the field of technical knowledge of drilling equipment and machines as well as the construction of drilling machines. are the main priorities. One of the important missions of the research and development unit has been the localization of the equipment needed for the construction of drilling machines, and this project has now been implemented. Our employees in the research and development unit of the company are the cornerstone of innovation and key elements for the development of new exploratory techniques.

Creativity in Dorkavosh technical engineering company is considered as an essential factor for cost-effective access to mineral resources. This means that our professionals will have the opportunity to grow in a dynamic environment where their expertise is valued throughout the company. Also, in order to empower the research and development unit in the company in order to provide the best performance in the industry and as an accepted principle in Derkavesh technical and engineering company, we continuously invest in training and facilities.
The current position of Dorkavosh Technical and Engineering Company as one of the suppliers of spare parts for drilling machines is being stabilized. Also, the drilling machines built to carry out exploratory work in the country’s mines are working with full power.
