U.S. market expects to see more oil and gas IPOs

Record high energy prices have generated big demand for initial public offerings of oil and gas companies and even if some of these deals tank, analysts say the deals are likely to keep coming.

So far, 11 oil and gas companies have made their debut in 2006, compared with seven at this time in 2005, five in 2004 and zero in 2003, according to data tracker Dealogic.
