03/31/94 PETROLEUM NEWS & QUOTES (AP) A potential frontier of new petroleum development and higher natural gas prices led to a sharp jump in bidding Wednesday for drilling tracts offshore from Louisiana, Alabama and Mississippi. High bids totaling $277 million were received as the federal government leased 375 blocks of nine square miles each in the Gulf of Mexico, the Minerals Management Service said. Eighty-two companies participated in the sale. That's up from last year's $69.1 million in high bids on 201 blocks. Much of the increased interest apparently stemmed from a successful well drilled off the Louisiana coast last year by Anadarko Petroleum Corp., Phillips Petroleum Co. and Amoco Production Co. The well showed there is oil and gas below a massive layer of salt that lies deep in the earth's crust. ``It's very, very early to make wide predictions,'' said Chris Oynes, acting regional director of the service. ``But the industry is looking at this as very considerable potential to add to reserves. One well is not going to prove this up. But this is adding another frontier area to look for oil and gas.''
