This was made known by the department on Monday via a statement published on its website.
It however, stated that the government was putting measures in place to produce oil from additional reserves in a bid to achieve the 40 billion barrels oil reserve target of the government.
According to the department, Nigeria had the capacity to produce about three million barrels of crude daily.
Crude oil production in Nigeria had revolved around 1.4 million barrels per day following the production cut recommended by the Organisation of Petroleum Exporting Countries.
Before the decision by OPEC and its allies to cut down crude production, Nigeria was producing around two million barrels of oil per day.
The Director/Chief Executive Officer, DPR, Auwalu Sarki, stated, “We identified all the discovered reserves. We have about 7,000 and we are producing from about 1,700 out of the 7,000 already discovered reservoirs.”
He added, “We took each of the producing reservoirs to see what kind of Enhance Oil Recovery that we need to put. So once we now put the EOR, that is secondary and tertiary recovery methods, technically we will grow the reserves.
“This is because those reserves are recoverable now and technically we will increase the production of the country.”
He said that this was a good platform for marginal oil fields to come in to help increase and grow the country’s reserves.
The chief executive officer said, “Remember we left over 40 million barrels fallow in 11 fields for 17 years. Now we have over 100 million which we want to grow within the next couple of months.”
