What was the problem?

In many cases, the crude oil that flows out of a newly drilled or a workover- performed oil production well is initially excessively sandy and acidic. Prior to 1999, this kind of crude oil used to be burnt in the burn pits and thus wasted for the first few days until crude oil with properties acceptable for feeding to production units was produced. However, while the crude oil was being burnt in the burn pits the resultant smoke caused serious air pollution, environmental damage and local aviation problem.

Innovative solution

In 1999, Chagalesh innovated,designed and built the first Mobile Oil Treating (MOT) package to solve the problem. Since then, through designing and producing several MOT packages , the following achievements have been earned:

  • Protection of the environment
  • Elimination of the aviation problem
  • Saving thousands of crude oil barrels annually
In this regard, Chagalesh received 2005 Kharazmi Scientific Festival Award for Innovation.
