AI summary

ONGC has struck gas at deepwater well MN-DW18-1-H-D in the Mahanadi Offshore Basin, off the Odisha coast, about 43 km from Konark. Drilled to a target depth of 1,623 metres, the gas hit was recorded at the 1,441-1,452 metre interval. The well has flowed gas with encouraging pressure for three days. The discovery is the first under the Samudra Manthan deepwater campaign and could be developed using shared facilities under PNG Rules 2025, supporting India's goal to expand domestic hydrocarbon resources.

Likely market impact

Positive exploration news; supports ONGC's deepwater growth pipeline, but commercial production still depends on further appraisal.
