enviromental clearance to OIL in Dibru-Saikhowa National Park!

Introduction:

 On 20 May 2020 OIL announced that it has received environmental clearance from the Ministry of Environment, Forest and Climate Change (MoEF) for its drilling project under Assam’s Dibru- Saikhowa National Park .It has laid to rest the concern regarding the affect drilling  may have on the flora and fauna of the region.

What was the concern?

  • Spread over 340 square kilometres, Dibru-Saikhowa is one of the five national parks in the north-east region’s most populous state- Assam.
  • The park, was declared  a biosphere reserve, in 1997 and is home to 36 mammal species including tiger, Gangetic dolphin, feral horses and 382 bird species.
  • It is an ecologically sensitive park.
  • It is the only region in India that supports the feral horses.
  • Drilling is likely to affect the flora and fauna of the region adversely.
  • Drilling will be inside the national park.
  • Dibru-Saikhowa is an island bounded by the Brahmaputra,Lohit and the Bibru river.

Highlights of OIL :

  • Operations will have no impact on the park’s area as they will be conducted 3.5 km beneath the surface.
  •  OIL will use the sophisticated ERD (extended reach drilling) technology that will enable the  exploration of  hydrocarbon deposits horizontally.
  • Drilling will take place at an average of more than 1.5 km outside the demarcated area of the national park.
  • By using this technology wells can be drilled up to a depth of approximately 4 kilometres from the existing well plinth without entering the protected area.
  • OIL is already carrying out hydrocarbon exploration for the last 15years in Baghjan area.

About Feral Horses:

  • A feral horse is a free-roaming horse of domesticated stock. As such, a feral horse is not a wild animal in the sense of an animal without domesticated ancestors. However, some populations of feral horses are managed as wildlife, and these horses often are popularly called “wild” horses.
  • IUCN Status is critically endangered.

About Extended Reach Drilling:

  • It is state of the art directional drilling technique for drilling beneath the surface of the earth.
  • It aims to reach larger area and longer distances.
  • It ensures maximum productivity and drainage capability.
