The Federal House of Representatives has opened investigations into a stolen $17 billion dollars crude oil deals.
The money was stolen through undeclared crude oil and liquefied natural gas exports to global destinations between 2011 and 2014.
NASS have requested 19 oil companies to submit a memorandum on their involvement.
They have continued to ignore that request.
Mobil Producing Nigeria, Chevron Petroleum and Esso Exploration and Production Nigeria, and seven others are involved in the theft.
THISDAY reports that the ad hoc committee set up by the House, sent letters to the IOCs six weeks ago.
Other IOCs that have shunned the request include Exxon Mobil, Star Deep Water Petroleum Ltd and Duke Oil.
More: Brass Oil Services Company Nigeria Ltd, Supreme Jute and Knitex Ltd, and Consolidated Oil Ltd.
Government agencies like NIMASA, NAPIMS, NPA and six other government agencies have failed to respond to NASS.
The Chairman of the committee, Hon. Abdulrazak Namdas, said a two-week ultimatum had been issued to them.
“Some of them who responded like the CBN, NNPC, and NLN) asked for more time to submit a memorandum.
“But we are giving a two-week grace, to everybody. The committee has to start its work,” he said.
“We hope to recover all illegal export and sale of Nigeria crude oil.
“If the monies are recovered from the identified buyers, it will go a long way to support development goals of the country,” Namdas said.
A report commissioned by former President Goodluck revealed that the country lost at least $17 billion to undeclared crude.
The report showed that undeclared 57,830,000 MT of Nigeria’s crude oil was sent to USA, China and Norway.
USA got crude worth well over $12 billion; China got crude worth over $3billion, and Norway got $839,522,600.
