Assam gas blowout: ONGC hopeful of plugging the leak by Friday
Oil and Natural Gas Corporation Limited ( ONGC ) in coordination with international well control specialists from CUDD Pressure Control , achieved a key breakthrough on Thursday in its ongoing operations at Well RDS#147A. It hopes to successfully cap the well by Friday. A statement issued by the ONGC said this on Thursday and added that this critical step culminated in the safe removal and dragging out of the rig substructure, thereby creating clear access to the wellhead and enabling preparations for the upcoming snubbing operation , an essential part of the final well control process. "Arrangements for the deployment of snub lines and other preparatory activities are now underway. This phase will include the careful removal of the existing Blowout Preventer (BOP), followed by the installation of a replacement unit as part of the well-capping strategy," the statement said. "In a carefully planned and precisely executed operation, ONGC successfully connected hydraulic lines to the existing BOP to pressurize the unit and operate the rams. The fact that this was accomplished without any visible increase in gas discharge stands as a strong validation of ONGC's technical assessment and strategic foresight. The operation unfolded exactly as anticipated, reflecting the depth of planning, accurate pressure analysis, and the disciplined execution that have guided ONGC's well control efforts throughout," it said. Adding to the momentum, favourable weather conditions throughout the day enabled the teams to maximise their productivity. The ONGC team worked in close coordination to leverage the dry weather window and execute key tasks with high efficiency. "In another positive development, the Dikhow River has shown a receding trend, reducing the immediate threat of flooding and supporting site accessibility and logistics," the statement said adding that with steady progress and a focused operational roadmap, ONGC is optimistic about completing the snubbing operation before sundown on Friday.

ONGC well blowout in Assam: Gas leakage continues for 15th day
Sivasagar, Jun 26 (PTI) Leakage of gas continued for the 15th day from a crude oil well of ONGC in Assam's Sivasagar district although the energy major on Thursday claimed that it is nearing to control the blowout. In its daily bulletin on the blowout, ONGC said it has achieved a key breakthrough in its ongoing operations in close coordination with international well control specialists from CUDD Pressure Control. "The team successfully cleared all remaining rig materials, including staircases, entangled wires and other structural components. "This critical step culminated in the safe removal and dragging out of the rig substructure, thereby creating clear access to the wellhead and enabling preparations for the upcoming snubbing operation, an essential part of the final well control process," it added. The company also said that it continues to make concerted efforts to control the unabated gas discharge from the well. The blowout took place on June 12 at Well No RDS 147A of Rig No SKP 135 of Rudrasagar oil field of Oil and Natural Gas Corporation (ONGC) at Barichuk of Bhatiapar. A private firm, SK Petro Services, was operating the well on behalf of the state-run Maharatna company. The statement further said that ONGC is optimistic about completing the snubbing operation before sundown on Friday with steady progress and a focused operational roadmap. "Arrangements for the deployment of snub lines and other preparatory activities are now underway. This phase will include the careful removal of the existing Blowout Preventer (BOP), followed by the installation of a replacement unit as part of the well-capping strategy," it added. In a carefully planned and precisely executed operation, ONGC successfully connected hydraulic lines to the existing BOP to pressurize the unit and operate the rams," the company said. The fact that this was accomplished without any visible increase in gas discharge stands as a strong validation of technical assessment and strategic foresight. "The operation unfolded exactly as anticipated, reflecting the depth of planning, accurate pressure analysis and the disciplined execution that have guided ONGC's well-control efforts throughout," it said. Adding to the momentum, favourable weather conditions throughout the day enabled the teams to maximise their productivity. The ONGC team worked to leverage the dry weather window and execute key tasks with high efficiency. The company also shared another positive development that the Dikhow river has shown a receding trend, reducing the immediate threat of flooding and supporting site accessibility and logistics. Water is being pumped continuously at high pressure from the Dikhow river, which is flowing near the rig. "The corporation remains committed to executing every stage of the operation with utmost precision, safety and environmental responsibility," it added. Three blowout experts from the US reached the site on June 20 and are actively engaged in the massive exercise to control the well. Last week, Assam Chief Minister Himanta Biswa Sarma had urged Petroleum and Natural Gas minister Hardeep S Puri to ask the energy major to ramp up their effort to control the blowout in a 'mission mode'. Sarma had also written to Puri and said locals believe that there has been "inadequate urgency and seriousness in ONGC's response" while trying to control the well. The prolonged nature of the incident is causing considerable distress in the surrounding villages as already more than 330 families have been evacuated from their homes and are being supported with basic relief and safety measures at a camp set up in nearby Bangaon. The Assam government has announced a financial aid of ₹ 25,000 each to about 350 families affected by the blowout. An official of ONGC had earlier said that it was an old crude well without production and a perforation job was going on for zone transfer at the time of the blowout.

ONGC says significant progress made in controlling gas blowout in Assam
In a statement, ONGC said it 'has made significant headway in its well control operations at RDS#147A, with the flow rate of gas having reduced substantially, marking a critical step forward in containment efforts.' The international expert team from CUDD Pressure Control, USA, who arrived on site on Friday, has conducted a preliminary assessment of the situation and reviewed all actions undertaken by ONGC teams so far. The blowout — or uncontrolled flow of natural gas — took place on June 12 at a well of the Rudrasagar oil field of ONGC at Barichuk. A private firm, S K Petro Services, was operating the well on behalf of the company. New Delhi, Jun 21 (PTI) State-owned Oil and Natural Gas Corporation (ONGC) on Saturday said it has made 'significant' headway in controlling the gas blowout at the Assam well, with flow rates reducing substantially. 'The experts have expressed their agreement with the strategy and execution carried out to date, reaffirming the effectiveness of ONGC's approach to safely managing the well,' the statement said without giving a timeframe by when the blowout will be fully controlled. ONGC said based on the forward plan jointly developed, extensive site preparations are underway to facilitate the next phase of action. The process of removing tubulars from the well has commenced, and mobilisation of cranes for the removal of tubing from the rig floor is in progress. 'Water blanketing continues around the clock as a key safety measure. Additionally, flood-level monitoring of the nearby Dikhow River remains ongoing, ensuring all operations are aligned with environmental and safety protocols,' the statement said. 'ONGC is continuously monitoring the low explosive limit (LEL) levels of air around the well site through real-time gas detectors to ensure safety. Medical assistance is being provided at the relief camp to support all those in need.' In a LinkedIn post, Oil Minister Hardeep Singh Puri on Friday said he has been reviewing the well control operation at the RDS 147 A at Sivasagar in Assam. 'The Crisis Management Team headed by experienced Blow Out Control specialists are on the job.' Residents in the vicinity had been relocated to a safe relief camp and arrangements for food, security and other essentials are being arranged by authorities concerned, he said, adding that the well is continuously blanketed by water to avoid fire as a safety measure. 'Composition of gas is found to be free from H2S, CO, and CO2. Being 97 per cent methane which is much lighter than air, it keeps going higher and higher. The gases are getting dispersed into heights and not settling on ground,' Puri said. He added that the air quality around the well site was being monitored continuously and was found to be in safe limits just at 50-100 metres distance from the well mouth. 'Considering the falling gas pressure which has fallen from 2600 psi to 500 psi, we are trying to contain the situation through junk shot operation and will try pumping kill fluids today. If it doesn't suffice and the fire is still not contained, capping of the well shall also be considered,' he added. PTI ANZ TRB This report is auto-generated from PTI news service.
