The Niger Delta Avengers, whose attacks on energy facilities in the region last year helped push Africa's biggest economy into recession, said on Friday it had ended its ceasefire in its campaign for more of Nigeria's oil earnings.
"We're constrained by cash," Emmanuel Ibe Kachikwu, the minister of state for petroleum, told Reuters in an interview on Monday when discussing efforts to develop the Delta. "We've scurried around for some money just to begin the process."
He said he would meet representatives of the militants and other stakeholders during a visit to the region on Nov. 9.
The minister said the government needed to develop its oil and economy to deliver on promises of more cash for the Delta, which rights groups say has long suffered from pollution and poor investment despite being the source for much of Nigeria's oil output of around 2 million barrels per day (bpd).
Kachikwu said a return to violence by the militants would be "mutually destructive", adding: "I am sure that like they did the last time, when they see a concrete action plan they would listen."
Attacks in the oil producing region drove Nigeria's oil output down to close to 1 million bpd. The Organization of the Petroleum Exporting granted Nigeria an exemption from a global deal to curb output to help it recover.
In its race to rebuild, Kachikwu said Shell <RDSa.L> and Eni (>> Eni) should press on with developing oil prospecting licence (OPL) 245. The $1.3 billion (£989.5 million) award of the block in 2011 is subject to corruption investigations and court cases. The firms deny wrongdoing.
"It's been allocated, and there are development plans for it (the block) and those development plans should go forward," Kachikwu said. "The development of assets should not suffer because we are dealing with a legacy transparency issue."
The minister said he intended to launch a "roadmap" in January inviting investors to fund repairs and upgrades to pipelines and oil depots, mirroring efforts that aim to draw $1.5 billion to $2 billion into Nigeria's ailing refineries.
Kachikwu said the plans would not involve selling state-owned stakes but attracting private capital was essential.
"We don't have the resources, and we don't have the time to raise the resources, to revamp the sector," he said.
On changes in the industry, the minister said revisions to oil contracts and operations at state oil company NNPC had saved money, citing deals to exchange crude for fuel, dubbed "direct sale, direct purchase", that saved the state $1 billion.
Nigeria has called for early talks to renew oil licences held by Shell, Total (>> Total) and others. Licences for several key fields expire in two years and oil firms are typically reluctant to make big investments without long-term assurances.
Kachikwu said such talks could be concluded by the first quarter of next year, although negotiations that are handled by the Department of Petroleum Resources had not yet started.
