The Chairman of the Committee, Sen. Tayo Alasoadura, gave the directive when the agency appeared before it for its budget defence.
The committee asked the agency to provide names of those recruited, their states of origin and other relevant details, to enable it determine if the recruitment process met the Federal Character requirements or not.
It further sought to know why the agency’s overhead cost went down by 50 percent and personnel cost went up by 20 percent.
The committee also requested for an explicit and detailed presentation of the agency’s Internally Generated Revenue (IGR) and how it utilized the money.
It further demanded to know who fixed the salaries of workers in the agency.
Responding, the DPR Director, Mordecai Ladan, assured the committee that all requested documents would be made available to it.
He added that there was nothing to worry about, as the federal character provision and other criteria were used in the recruitment process.
While confirming that the agency recruited over 500 workers, he said necessary procedures were followed in the recruitment.
Laban said: “When we wanted to recruit, we informed all relevant committees in the National Assembly.
“Advertisements came out in November 2016, although there were things that needed to be sorted out and that made the process to last for six months and over 700, 000 people applied.
“The interview was conducted after one year.
“The Federal Character Commission was involved in the process and every state was taken care of in the recruitment, catchment area was also used.”
The DPR, a department under Federal Ministry of Petroleum Resources (FMPR), is the leading regulator of the Nigerian oil industry.
