  • TERI Study on Air Quality & Noise Level: Recording of data at already installed analysers is in progress.Sample collection for monitoring of air quality and noise levelfor analysis isalso being carried out.
  • TERI study on Bioremediation of Sludge:Site preparation prior to bio remediation jobin high land areas along the roadside from Kaliapani Bridge to Baghjan village is in progress.
  • CSIR-NEIST Seismological Study: Seismological recording in the vicinity of Baghajan Blowout Well by CSIR-NEIST has been completed. Data is being analyzed for submission of final report. Other Geo-Physical monitoring is being continued by CSIR- NEIST.
  • IIT– Guwahati Study on Thermal Mapping & Sonic Measurement:Data collections by IIT-G Team for thermal imaging and sound measurement at required areas have been completed. Interpretation of the data will be carried out using specialized software at IIT Guwahati and the report will be submitted soon.


Preparation for Capping the Well

  • Excavation of Ramps and Cellar: Completed
  • Opening of Well Head Flange: Completed
  • Injured Alert Experts: The experts from Alert who sustained minor burn injury arerecovering well and are under constant supervision of OIL doctors.

  • Other Fabrication Job: Fabrication jobs as per the requirement are being carried out at site Workshop facility.
  • Water Deluge System: Five numbers of High Discharge CMT Water Pumps are in operation at site for spraying water to the well head during theoperation. One CMT High Discharge pump is under servicing.  Total 8 nos. of water pumps are available for filling both the water reservoirs periodically.

Relief and Rehabilitation

  • Surveyfor Damage Assessment: Survey for assessment of damage for compensation in both Tinsukia and Doomdooma Circle is in progress. Total number of families surveyed till 23.07.2020 both combined in Doomdooma andTinsukia circle is

Law and Order/Bandhs/Blockades etc.

  • Closure of Wells: Fewoil/gas wells under Baghjan EPS arecontinued to be shut-in forced by protesters.
  • Blockade at Drilling/Workover Locations: Operation at 2drilling locations and 3workover locations continue to be obstructed.

Impact onOil/GasProduction due to Protests

  • Due to stoppage/blockades, there was production loss of 317 MT of Crude Oil and 1.15 MMSCM of Natural Gas as reported on 23-07-2020. Operations were disrupted in 11 Oil wells & 05 gas wells. Cumulative production loss since 27th May, 2020 due to bandhs and blockades: 16217 MT Crude oil, 36.32 MMSCM of natural gas.
