**Gas Leak Continues for 15 Days at ONGC Well in Assam**
A gas leak from a crude oil well operated by ONGC in Assam’s Sivasagar district has persisted for 15 days, although the company announced progress in controlling the blowout. In its latest update, ONGC reported a significant breakthrough in collaboration with international well control experts from CUDD Pressure Control.
The team successfully removed all remaining rig materials, including staircases and entangled wires, which allowed for the safe extraction of the rig substructure. This crucial step has provided clear access to the wellhead, facilitating preparations for the upcoming snubbing operation, a vital component of the final well control process.
The blowout occurred on June 12 at Well No RDS 147A of Rig No SKP 135 in the Rudrasagar oil field, where a private firm, SK Petro Services, was operating on behalf of ONGC. The company expressed optimism about completing the snubbing operation by Friday evening, citing steady progress and a focused operational plan. Preparations for deploying snub lines and other necessary activities are currently underway, which will include the careful removal of the existing Blowout Preventer (BOP) and the installation of a replacement unit as part of the well-capping strategy.
ONGC has successfully connected hydraulic lines to the existing BOP to pressurize the unit and operate the rams, achieving this without any noticeable increase in gas discharge. This accomplishment underscores the effectiveness of their technical assessment and strategic planning. Favorable weather conditions have further aided the teams in maximizing productivity, allowing them to execute critical tasks efficiently.
Additionally, the Dikhow River has shown a receding trend, reducing the immediate risk of flooding and improving site accessibility. Continuous high-pressure water pumping from the river, which flows near the rig, is ongoing. ONGC remains committed to executing every phase of the operation with precision, safety, and environmental responsibility.
Three blowout experts from the United States arrived on June 20 and are actively involved in the ongoing efforts to control the situation.
