Blowout in Gas Well of Oil India Limited at Baghjan, Tinsukia 29 July 2020

Environmental Impact Assessment

  • TERI Study on Air Quality & Noise Level: Recording of data at already installed analysers and sample collection for monitoring of air quality and noise levelare in progress.
  • TERI study on Bioremediation of Sludge:Clearing of site prior to bio remediation in wetland areas is being carried out. Site preparations for ex/in-situ bio remediation job in affected areas are in progress.
  • 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: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

  • Final Preparation for Capping Operation:All high pressure well control equipment were placed at the designated positions as per plan which included Choke manifold, Ground X- mass tree, BOP control unit and all associated high pressure lines/hoses. Heat shields are placed to shield these equipment.  The modified riser was also rigged up to the BOP stack, thus completing the capping stack. Jobs lined up for today include: (i) Laying of remaining portion of the piping from the pumper unit up to the well head for pumping killing fluid (ii) Laying of high pressure hoses connecting the choke manifold / Ground X- mass tree and the hydraulic lines from the BOP Control unit to the well head.Considering the criticality of the well capping and subsequent killing operations, a dummy run is being planned to be carried out with all support heavy machinery before the final capping operations.
  • Final Preparation for Killing Operation:Transferring and unloading of WellKilling Fluid at the site is completed andready for killing operation.
  • 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. Numbers of families surveyed till 28.07.2020 in Doomdooma and Tinsukia Circle are 596 and 1759 Total number of families surveyed till 28.07.2020 both combined in Doomdooma andTinsukia circle is 2355. 

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 of several producing wells, there was production loss of 321 MT of Crude Oil and 1.22 MMSCM of Natural Gas as reported on 28-07-2020. Cumulative production loss since 27th May, 2020 due to bandhs and blockades: 17646 MT Crude oil, 41.83 MMSCM of natural gas.
