IOC Chairman B Ashok said the freedom allowed the companies to decide on tenders for purchase of crude oil within a very short span of time.
"Earlier we used to take 36 hours to formalise a tender. This time was considered too much considering crude oil prices change every minute. This time has now been brought down to less than two hours," he told reporters here.
The flexibility given in April last year allowed companies to decide on buying crude oil from spot or current market on their own instead of previous practice of a committee comprising company officials and a representative of the Oil Ministry deciding that.
"Term crude volumes used to be as high as 80 per cent (of all the crude oil imported). We have brought it down to 68 per cent," he said.
