NEW YORK, April 6 (Reuters) - The initial public offering of SandRidge Energy's (SD.N) royalty trust, SandRidge Mississippian Trust I, raised $315 million on Wednesday, selling more common units than planned at the top of the proposed price range.
The trust sold 15 million units for $21 each. It had planned to sell 12.5 million units for $19 to $21 each.
The IPO comes at the time when oil prices continue their steep climb and at the forefront of a string of offerings that are expected to tap investor interest in energy and natural resources stocks. [ID:nN05169962]
The trust will own royalty interest in SandRidge's 37 oil and gas wells operating in Oklahoma and another 123 wells the company is expected to drill once the offering is complete.
Through the royalty interest, the trust will receive a portion of what SandRidge makes on the sale of oil extracted from the wells.
SandRidge Energy will receive the proceeds from the IPO and plans to use them to repay debt and for general corporate purposes that may include drilling the new wells.
Turmoil in the Middle East has sent oil prices surging in the recent weeks. U.S. crude oil futures CLc1 have been trading above $108 a barrel, the highest in two and a half years.
Sources have told Reuters that several bigger energy and commodities companies could float later this year, while many smaller players all across the board within natural resources, energy and commodities are also weighing such plans.
