Global crude oil prices have nearly doubled in the last one year but government has not raised domestic fuel prices on a direction from United Progressive Alliance chairperson Sonia Gandhi, Petroleum Minister Murli Deora said in Lok Sabha on Thursday.

"I have no hesitation in saying that the UPA chairperson had directed us to see that petroleum product prices do not increase and we are trying to do that," Deora said.

There has been a marked increase in prices of crude oil to nearly $100 per barrel a day from $40-45 dollars last year but government has not increased prices even by one rupee, he said.

Petrol, diesel, LPG and kerosene are at same price level as of last year, the minister said.

Replying to another query, Deora said punitive action would be taken against companies for not completing the committed work programme for areas awarded to them under the New Exploration Licensing Policy (NELP) since 2000.

"We are, however, trying that the companies finish their committed work programme within the given time-frame," he said.

NELP was introduced to lower import dependence for petroleum products, the minister said.
