Energy exploration company Delta Petroleum Corp. filed a chapter 11 reorganization plan giving ownership stakes in a newly created company to creditors after years of losing money trying to find and extract natural gas pockets in and around the Rocky Mountains, Dow Jones DBR Small Cap reported today. The lending agent behind the company's $67.2 million bankruptcy loan and nearly 80 percent of groups who hold the company's biggest debt of $267.7 million have already agreed to accept the plan.
