Environmental Impact Assessment

  • 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: The first phase of sample collection prior to bio remediation job is being carried out along the road side from NotunGaon area to Baghjan blow out well site.
  • CSIR-NEIST Seismological Study: Seismological recording carried out by CSIR-NEIST has been completed. Data is being analysed for submission of final report. Other Geo-Physical monitoring is being continued by CSIR- NEIST.
  • IIT– Guwahati Study on Thermal Mapping & Sonic Measurement:Interpretation of the collecteddata will be carried out using specialized software at IIT Guwahati and the report will be submitted soon.

Preparation for Capping the Well:

  • Final Preparation for Capping Operation: Removal of the valve and flange at both side of casing head spool has been completed yesterday.  Three studs at one side could not be removed due to deformity caused by heat.Four numbers of VR Plugs are modified/fabricated on war-footing at OIL’s Engineering workshop under constant supervision of OIL engineers overnight yesterday and were sent to wellsite early this morning. The smoke pipe repairing/welding job is underway at workshop till the time of reporting. Fixing of new valve & VR plug is expected to be completed today, following which preparations for capping like positioning of equipment, HP lines etc., would be undertaken.
  • Final Preparation for Killing Operation:Final treatment of well killing fluid is underway to ensure required viscosity and weight.
  • Water Deluge System: All six numbers of High Discharge CMT Water Pumps are operational at site for spraying water to the well head during theoperation. 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 Doomdooma and TinsukiaCircle is in progress. Total number of families surveyed till 25.07.2020 both combined in Doomdooma andTinsukia circle is 2140.

Law and Order/Bandhs/Blockades etc

  • Closure of Wells: Production still continues to be affected due to forceful closure of few Oil & Gas wells connected to Baghjan EPS.
  • Blockade at Drilling/Workover Locations: Drilling and workover operation still continue to be affected due to forceful closure of operation at few of the locations.

Impact onOil/GasProduction due to Protests

  • Due to stoppage/blockades, there was production loss of 283 MT of Crude Oil and 1.11 MMSCM of Natural Gas as reported on 25-07-2020. Operations were disrupted in 11 Oil wells & 05 gas wells. Cumulative production loss since 27th May, 2020 due to bandhs and blockades: 16817 MT Crude oil, 38.57 MMSCM of natural gas.
