The Senate approved legislation Saturday to implement a U.S.-Mexico pact that would enable offshore drilling cooperation along a maritime boundary in the Gulf of Mexico.

The bill to implement the 2012 U.S.-Mexico Transboundary Hydrocarbons Agreement quickly cleared the Senate by “unanimous consent,” avoiding a roll call vote.

The drilling pact – which backers say would provide legal certainty needed to enable development along the Gulf boundary – has bipartisan support. But the Senate legislation differs from a House-approved version of the implementing bill.
