The Institute of Drilling Technology (IDT) was set up in
1978 at Dehradun. Located in the picturesque valley of Doon
between the green Shivaliks and the lower Himalayas, it is
engaged in relentless effort in R&D and has rendered excellent
services in the area of oil and gas well drilling technology.
Over the years, the Institute has emerged as a premier R&D
centre in South East Asia, capable of providing advance technical
knowledge through training and offering plausible solution
to field problems.
The Institute with highly qualified and experienced scientists
and engineers, carries out applied research in all facets
of drilling related activities to achieve technical excellence
in R&D efforts and assimilation of emerging technologies.

The integrated HRD division imparts training to participants
from both national and international oil companies in various
aspects of oil well drilling technologies. The renowned Well
Control School at IDT has been accredited by International
Well Control Forum, The Netherlands, International
Alliance for Well Control, the Netherlands, and also from
International Association of Drilling Contractors,
USA.
The infrastructure for applied R&D has been developed
with the state-of-the-art equipment and machines to achieve
qualitative experimental results. Focus of R&D is directed
towards drilling technology, drilling fluid engineering and
cementation and cementing materials to meet challenges of
drilling industry. The technologists and scientists provide
solutions to the down hole drilling problems, improving design
of the systems and thereby contributing towards the development
of excellent, efficient and cost effective operations.
