The strike by oil PSU officers on Thursday entered the second day as the threat of fuel supply disruptions loomed large.
The officers of 13 oil PSUs stayed away from work, which hit oil and gas production at Western Offshore.
Oil Sector officers Association leadership continued to remain underground with no fresh arrests happening. Two ONGC officers association members were arrested on Wednesday and there have been no further arrest.
"As of now we are maintaining fuel supply at petrol pumps and continue operating aviation services at airports but if the strike continues for another one or two days there are bound to be dry ups at petrol pumps," Indian Oil Corporation Chairman Sarthak Behuria told PTI.
Behuria said aviation refuelling services were being discharged at some airports with a slight delay as only one shift of normal staff was present doing the refuelling.
Gail Chairman UD Choubey said the nation's main trunk pipeline Hazira-Vijaypur-Jagdishpur (HVJ) continued to remain out of operation as ONGC failed to supply natural gas.
ONGC Chairman R S Sharma is likely to visit Hazira later in the day in an attempt to convince the company officers to resume production from the main gas field in the Western offshore.
