CASPER, Wyo. (AP) — A 5,000-well oil and gas project is being proposed for east-central Wyoming that would cover 1.5 million acres (607,000 hectares).

Five major oil and gas companies proposed the joint project just north of Interstate 25 between Glenrock and Douglas in Converse County. The drilling would occur over a period of 10 years, and each proposed well is expected to last about 30 years.

Anadarko Resources, Chesapeake Energy, EOG Resources, SM Energy and Devon Energy are the partners on the proposal.

The Bureau of Land Management anticipates the project will generate more than 8,000 jobs and between $18 billion and $28 billion in revenue.

The size and scope of the project has some concerned.

Public comment is open until March 12.
