Olso

Olso, Norway-based Norsk Hydro said Monday that it locked in price collars on the majority of Spinnaker Exploration’s oil and gas production for the next three years. Spinnaker’s shareholders will vote next month on whether to approve a proposed $2.56 billion buyout by Hydro, which expects to conclude the acquisition immediately after the shareholder vote (see Daily GPI, Sept. 20).
