To amend the Mineral Leasing Act to provide for commingling.

This bill amends the Mineral Leasing Act to allow the Secretary of the Interior to approve commingling of production from multiple sources before royalty measurement, in order to reduce surface disturbance.

Section 1, Commingling under Mineral Leasing Act: The bill redesignates existing subsections (h) through (q) as (i) through (r) and adds a new subsection (h) on commingling. This new subsection requires the Secretary of the Interior to approve applications for commingling production from two or more sources, such as oil and gas leases, unit participating areas, communitized areas, or non-Federal or non-Indian properties, before the point of royalty measurement, regardless of ownership, royalty rates, or acreage. The applicant must agree to either install measurement devices for each source or use an allocation meter or method that achieves volume measurement uncertainty within plus or minus 2 percent during the production phase, reported on a monthly basis.
