About OIL

  • Oil India Limited is the second largest hydrocarbon exploration and production Indian public sector company with its operational headquarters in Duliajan, Assam, India.
  • A Navratna PSU, OIL is a fully integrated Exploration & Production (E&P) company in the upstream sector.
  • OIL was drilling a well at Baghjan which led to a massive blowout. Baghjan is about 17 km from Doomdooma town in Tinsukia district, Assam.
  • The Baghjan oil field has been in operation since 2003 and is one of the high yielding gas and oil fields of OIL.
  • The Baghjan oilfield has 21 functioning wells — four of them are gas wells (including the one that reported the blowout) and 17 are oil wells.

The ecological disaster

  • The ecological disaster atBaghjan in Tinsuika district was precipitated by the blowout at well number 5, reported on May 27.
  • On June 9, the well—located close to the Dibru-Saikhowa national park—caught fire, leading to the deaths of two OIL firefighters.
  • Around 11,000 people from the surrounding villages are now in relief camps set up by the administration.
  • It affected the flora, fauna and wetlands which is close to the Maguri-Motapung wetlandand the ecologically fragile Dibru-Saikhowa National Park.

Dibru-Saikhowa National Park

  • Dibru-Saikhowa National Park is located in the Tinsukia district of the state of Assam.
  • This was declared a wildlife Sanctuary in 1986by the government of Assam by uniting two Reserve forest, viz., Dibru and Saikhowa including some other areas.
  • Dibru-Saikhowa wildlife Sanctuary was declared as a National park in 1999.
  • Dibru-Saikhowa National Park is one of the 19 biodiversity hotspotsin the world. It is also a biosphere reserve.
  • The park is bounded by the Brahmaputra River and Arunachal hills in the north and Dibru and Patkai hills on the south.
  • It mainly consists of semi wet evergreen forests, tropical moist deciduous forest, bamboo, cane brakes and grasslands. Situated in the flood plains of Brahmaputra, at an altitude of about 118 m above sea level.

Maguri-Motapung wetland

  • Located less than 10 km south of Dibru-Saikhowa National Park is Maguri Motapung beel.
  • Spread over 9.6 sq. km, Maguri Motapung beel was declared an important bird and biodiversity area in 1996.
  • It is host to over 110 bird species, including eight listed as threatened on the IUCN Redlist, such as the swamp grass babbler, the ferruginous duck, the white-winged wood duck and the falcated duck.
  • Other rare and migratory birds that visit this wetland include the lesser adjutant, the swamp francolin, the lesser teal and the bar-headed goose.
  • It is also home to 84 species of fish, including the golden mahseer

Is it first time?

  • Though rare, blowout happens in the oil industry all over the world. Blowout is the worst thing that can happen to an oil industry.
  • ONGC offshore rig ( drilling inside the sea bed), 160 km from Mumbai had a massive blowout in 2005, another blow out at Rudrasagar, Sivsagar of a well belonging to ONGC, a blow out at Dikom, Dibrugarh district in the year 2005 when OIL drilled a well, are few examples.
  • During Dikom blowout, global experts were brought in to contain the blowout which took 45 days.
  • So Baghjan is the second blowout for OIL after a long 15 years.
