The assurance is contained in a statement issued in Abuja on Monday by Mrs Chinwe Agulefo, the Acting Group General Manager, Public Affairs of the NNPC.
The statement said the corporation had more than 32-day sufficiency of petroleum products.
It said the corporation was working hard with relevant stakeholders to reduce the impact of the disruption in the supply of petroleum products as result of the strike.
It noted that the relevant stakeholders were already working with the union to ensure quick resolution of issues at stake.
The statement called on members of the public to refrain from panic buying or hoarding of petroleum products.
NUPENG began a three-day warning strike on Monday to demand for better working conditions for its members.
The strike had led the emergence of long queues at filling stations in Abuja and some other parts of the country.
