Preparation for Capping the Well: As advised by Alert and ONGC team, considering the overall operational safety during well capping and well killing operation, it has been decided to fabricate a scissor-type ‘C’-plate for placement of liquid resin on top of the slips in an attempt to create a temporary ‘pack-off’ of the annular section from exposure to direct well bore pressure upon closing of the BOP. Fabrication of this scissor-type ‘C’-plate has already been completed at OIL’s Engineering Workshop and also transferred to the site. The placement of resins would now be carried out in two instalments, each consuming around 24 hours as setting time. This entire process is expected to take around 72-96 hours. All efforts are being taken to control the well at the earliest. Treatment of killing fluid is in progress too at site.
Relief and Rehabilitation: A total of 2756 number of families have been surveyed for assessment of damage for compensation till 12.08.2020 in Doomdooma and Tinsukia Circle put together.
Law and Order/Bandhs/Blockades etc.: Oil & Gas Production still continues to be affected due to forceful closure of few Oil & Gas wells connected to Baghjan EPS. Drilling and workover operation also continue to be affected at few of the locations due to forceful closure of operation.
Impact on Oil/Gas Production due to Protests: A total of 26923 Metric Tonnes of Crude Oil and 64.44 Million Metric St. Cubic Meter of Natural Gas have been lost respectively as a result of protests/blockades/ bandhs in and around Baghjan area since 27th May, 2020 due to the Blowout.
Environmental Impact Assessment: Environmental Impact Assessment (EIA) study on various parameters are being carried out by various agencies, viz. M/s TERI, M/s ERM, M/s CSIR-NEIST, IIT-Guwahati apart from OIL’s in-house monitoring of Air quality/Noise level/Gas presence. Bio remediation activities at affected areas are also in progress.
