Indian ONGC likely to abandon hydrocarbon exploration in Bay

Indian oil and gas exploration company ONGC Videsh Ltd (OVL) is set to abandon its hydrocarbon exploration efforts in two Bangladeshi offshore gas blocks after a decade of operations.
OVL -- the sole international contractor assigned to delineate hydrocarbons in Bangladesh's offshore blocks -- has neither sought to extend its contract tenure nor initiated new well drilling projects before the contract expiration in February 2025, according to a senior Petrobangla official.
Instead, it requested to relocate its two shallow sea blocks to more promising areas in the Bay of Bengal and increase gas prices, the official told The Financial Express on Wednesday.
"It is a clear indication that the Indian firm is not interested in continuing exploration in Bangladesh," said a senior official of the Energy and Mineral Resources Division under the Ministry of Power, Energy, and Mineral Resources.
State-run Petrobangla has never increased tariffs after signing production-sharing contracts (PSCs) or allowed block relocation.
OVL is currently the only international oil company (IOC) with rights to explore two untapped shallow offshore blocks in the Bay of Bengal.
But it has halted its well-drilling activities for the past two years, violating contractual obligations, said the Energy and Mineral Resources Division official.
"After a failed exploration attempt at Kanchan under the SS-04 block in Moheshkhali Island a few years ago, the Indian company did not proceed with its exploration works," said a senior Petrobangla official.
It could not find any commercially viable hydrocarbon resources at Kanchan after drilling a well, he said.
Under the PSC with OVL, the oil and gas exploration company has contractual obligations to drill two more wells: 'Titly' in block SS-04 and 'Moitree' in block SS-09. But OVL management has yet to engage a contractor for the well drilling.
With only a few months remaining in its PSC tenure, the Indian firm is unlikely to complete drilling within the given time, said sources.
They added that the firm has a budget of US$65 million for drilling the wells.
Delays and failures
OVL signed two PSCs with Petrobangla in February 2014, securing rights to explore shallow sea blocks SS-04 and SS-09. These contracts were initially set to expire in February 2019.
Petrobangla extended the PSC tenure twice to boost offshore exploration -- first until February 2023 and then to February 2025. Both extensions were granted at OVL's request following failed exploration attempts.
At Kanchan gas well, OVL drilled beyond its targeted depth of around 4,228 metres in search of a commercially viable gas deposit. But all its efforts found only huge deposits of clay and shell-stone sequence and no sandstone, meaning there is no gas reserve there.
The Kanchan well was up for the first offshore drilling in the country's maritime territory in the last seven years.
Obligations and progress
OVL is the operator of blocks SS-04 and SS-09, having a participating stake of 45 per cent. Block SS-04 covers an area of 7,269 square kilometres, while block SS-09 stretches over an area of 7,026 square kilometres. The water depth of both the blocks ranges between 20 metres and 200 metres.
As per the PSC, the firm is committed to conducting 2,700 line-kilometre 2D seismic-data acquisition and processing as well as drilling one exploratory well in block SS-04.
Also, it has to do the same for another 2,700 line-km 2D seismic- data acquisition and processing as well as drill two exploratory wells in block SS-09.
The OVL owners will be allowed to operate and sell oil and gas for 20 years from an oil field and 25 years from a gas field under the deals. The company has already completed around 3,100 line-km 2D seismic surveys for both blocks.
Currently, the country has no producing offshore gas wells, as its entire natural gas output comes from onshore fields and the import of liquefied natural gas (LNG).
