ONGC contains gas leak at Assam's Rudrasagar well site on 15th day

State-owned national oil and gas major ONGC has successfully stopped the natural gas leak at the Rudrasagar gas field in Assam, which had been leaking for the past 15 days. On Friday, ONGC announced that capping operations had been successfully completed at the RDS 147A well site in Sivasagar district. 'This blowout started on June 12 and has been capped successfully within the shortest possible time following all the best practices,' Petroleum and Natural Gas Minister Hardeep Singh Puri said in a post on X. ONGC's Crisis Management Team (CMT), along with experts from Texas-based Cudd Pressure Control, completed the critical operation to safely remove the damaged blowout preventer (BOP) from the wellhead. 'The effort was carried out with high precision and coordination to ensure stability and prevent any imbalance or toppling during the lifting process,' ONGC said in a statement. Once the BOP was safely removed, the pre-positioned capping stack, prepared at the staging area, was carefully and accurately placed onto the wellhead. This redirected the gas flow securely to the top of the capping stack, allowing containment. Before this, an extra-long boom crane and a 40-tonne crane had been used to remove the 42 tubing stands from the derrick of the rig, clearing the path for the safe removal of the rig base from the wellhead. The gas leak had sparked widespread fear, prompting the evacuation of 330 families from surrounding areas as a precautionary measure. The first team of mining engineers and experts from the United States reached the gas field on June 20—the eighth day after the leak began. The team included experts from the International Well Control Agency. Rudrasagar is one of India's oldest production sites, operational since 1960, and is located on the outskirts of district headquarters Sivasagar. More than 1,500 people from villages around the rig were evacuated. In June 2020, a similar gas well blowout at Oil India Limited's Baghjan gas field in Assam's Tinsukia district resulted in three deaths and large-scale evacuation.

ONGC well blowout: Gas leak continues for 5th day, ‘most experienced' team engaged

The blowout began on June 12 at Well No RDS 147 of Rig No SKP 135 of Rudrasagar oil field of ONGC at Barichuk of Bhatiapar. A private firm, SK Petro Services, was operating the well on behalf of the state-run Maharatna company. The district administration said that air pollution is still within the acceptable limit and the local office of Pollution Control Board, Assam (PCBA) is closely monitoring the situation. Sivasagar (Assam), Jun 16 (PTI) Energy major ONGC on Monday said it has deployed the 'most experienced' Crisis Management Team (CMT) to control the leakage of gas, which continued for the fifth day after a blowout at a crude oil well in Assam's Sivasagar district. 'ONGC has deployed its most experienced Crisis Management Team (CMT), a team with a proven track record in managing complex well control operations, to contain the gas leakage at Well RDS#147. The operation is being closely and continuously monitored by ONGC's top management,' the company said in a statement. Geological challenges are inherent to oil and gas operations and the premier energy company follows stringent safety protocols, it added. 'ONGC is making all out efforts to bring the gas leak under complete control at the earliest,' the company said. The company, in coordination with the district administration, undertook the safe evacuation of affected families and has been providing them with shelter, food, drinking water and other essential daily supplies. Because of the blowout, around 1,500 people have been affected and 70 families were shifted to a relief camp set up in nearby Bangaon, and all necessary arrangements are being made to ensure their welfare and well-being. 'To safeguard public health, ONGC has established free round-the-clock medical camps staffed with doctors and equipped with essential medicines, as part of its comprehensive emergency response,' the statement said. The company said that it is maintaining continuous communication with all stakeholders, including the district and police administrations, media and local community leaders, to ensure transparency and swift action. 'ONGC is grateful to the government, the local residents and the media for their continuous support and seeks further cooperation from all stakeholders till this situation is normalised,' it added. Meanwhile, the office of the Sivasagar District Commissioner in a Facebook post said that the local PCBA unit has established machines at the blowout site to study the air quality and oversee other pollution levels. 'According to the test reports by experts on the level of pollution in the atmosphere, the air pollution is still within tolerable limits,' it added. Measures have been taken to reduce the spread of compounds in the exhaust gas into the atmosphere by continuously pumping water at high pressure from the Dikhou river which flows near the rig. The well has not caught fire yet and no one is injured in the incident, while all emergency services have been pressed in the area, a company official said. An ONGC official 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. 'It is a kind of servicing of the well. The production was supposed to start from a new zone after the perforation job. At the time of the incident, the logging perforation operation was going on. Suddenly gas started coming out in an uncontrolled manner immediately after the perforation, leading to the blowout,' he had added. PTI TR NN This report is auto-generated from PTI news service.

ONGC well blowout in Assam: Gas leak continues for fourth day, 70 families shifted

Sivasagar , Leakage of gas continued for the fourth day at a crude oil well of energy major ONGC in Assam's Sivasagar district, where around 1,500 people have been affected by the blowout and 70 families shifted to a relief camp, officials said. Assam Chief Minister Himanta Biswa Sarma said the government is concerned about the blowout, which is yet to be controlled. "The chief secretary has spoken to the company officials. We are in touch with ONGC and came to know that more experts have reached the spot," he told reporters in Dibrugarh. ONGC Director Vikram Saxena reached the spot on Saturday and a team led by him took over operational control of well no. RDS 147, where the blowout took place. "The well killing process is going on, and we have mobilised all necessary equipment for the same. The Crisis Management Team is working on war-footing to control the leakage," an official told PTI. The well has not caught fire yet and no one is injured in the incident, while all emergency services have been pressed in the area, he added. The blowout took place on June 12 at well no. RDS 147 of rig no. SKP 135 of Rudrasagar oil field of ONGC at Barichuk of Bhatiapar. A private firm, SK Petro Services, was operating the well on behalf of the state-run Maharatna company. "A comprehensive well control plan has been formulated, and pumping operations commenced following the successful installation and testing of essential connections," ONGC said in a statement. A joint team of ONGC Assam Asset and the Sivasagar district administration is actively engaging with local residents, who were evacuated from nearby areas as a precautionary safety measure, it added. A senior official of the Sivasagar district administration told PTI that around 1,500 people have been affected in the vicinity of the well. "They are getting the smell of gas and are not able to light their stoves or burn anything. We are providing them with cooked food and constantly monitoring the situation," she added. From the area of the blowout, 70 families have been shifted to a relief camp set up in nearby Bangaon and all necessary arrangements are being made to ensure their welfare and well-being, the Sivasagar district administration said in a Facebook post. "There are currently doctors from the Health Department and Animal Husbandry Department at the scene. They are examining the health conditions of both people and their domestic animals," it added. Raijor Dal president and Sivasagar MLA Akhil Gogoi visited the blowout site in the morning and discussed the ongoing exercise with senior ONGC officials. "They tried to cap the well yesterday, but failed. They are working on it now and will be able to tell tomorrow how long it might take to finally stop the gas leakage," he told reporters after his meeting with ONGC senior officials. Gogoi said that ONGC officials told him it might take at least three more days to fully control the well due to the huge pressure of gas. "They also told me about a geographical wonder. This was a crude oil well, but they discovered a huge reserve of gas. According to them, this well alone can supply gas to entire Assam for the next 125 years," he claimed. 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. "It is a kind of servicing of the well. The production was supposed to start from a new zone after the perforation job. At the time of the incident, the logging perforation operation was going on. Suddenly gas started coming out in an uncontrolled manner immediately after the perforation, leading to the blowout," he had added. This ONGC incident reminded people of the worst industrial disaster of the Northeast in 2020, when an OIL well blowout took away the lives of three employees of the PSU major and injured several others. Well no. 5 at Baghjan in Tinsukia district spewed gas uncontrollably for 173 days since May 27 and it caught fire on June 9, 2020. In a multi-agency effort, the damaged gas well at Baghjan in Assam was 'killed' and the blaze was fully doused on November 15, followed by abandoning of the well on December 3 in 2020 after completing all steps to control it.
