WASHINGTON, D.C. – As part of the Bipartisan Budget Act, President Barack Obama has signed the US-Mexico Transboundary Hydrocarbons Agreement into law. The agreement establishes a framework for US offshore oil and gas companies and Mexico’s Petroleos Mexicanos (PEMEX) to jointly develop transboundary reservoirs.

Secretary of the Interior Sally Jewell said: “I applaud the House and Senate for working together to pass this important agreement, which supports the responsible expansion of domestic energy production. The agreement makes available promising areas in the resource-richGulf of Mexico and establishes a clear process by which both governments can provide the necessary oversight to ensure exploration and development activities are conducted safely.”

The Transboundary Agreement removes uncertainties regarding development of transboundary resources in the Gulf of Mexico. As a result of the agreement, nearly 1.5 million acres (6,070 sq km) of the US outer continental shelf will now be made more accessible for exploration and production activities. The Bureau of Ocean Energy Management estimates this area contains as much as 172 MMbbl of oil and 304 bcf (8.6 bcm) of natural gas.

The agreement also opens up resources in the Western Gap that were off limits to both countries under a previous treaty that imposed a moratorium along the boundary.

In May 2010, Presidents Obama and Calderon committed to reaching an agreement to jointly develop reservoirs that were determined to be transboundary. Since that time, representatives from the US Department of State, the US Department of the Interior, and Mexico’s Foreign Ministry and Ministry of Energy worked to negotiate an agreement that can be implemented while respecting each nation’s legal framework.

In February 2012, then-Secretary of the Interior Ken Salazar joined Mexican President Felipe Calderon, Secretary of State Hillary Rodham Clinton, Mexican Minister of Foreign Relations Patricia Espinosa, and Mexican Minister of Energy Jordy Herrera in Los Cabos, Mexico to sign an agreement on the exploration and development of oil and natural gas reservoirs along the United States’ and Mexico’smaritime boundary in the Gulf of Mexico. Mexico’s legislature passed the legislation in April 2012.

The Transboundary Agreement sets clear guidelines for the development of oil and natural gas reservoirs that cross the maritime boundary. Under the agreement, US companies and PEMEX will be able to voluntarily enter into agreements to jointly develop those reservoirs. In the event that consensus cannot be reached, the Transboundary Agreement establishes the process through which US companies and PEMEX can individually develop the resources on each side of the border while protecting each nation’s interests and resources.

The Transboundary Agreement also provides for joint inspection teams from the Bureau of Safety and Environmental Enforcement and the Mexican government to ensure compliance with applicable laws and regulations. Relevant agencies on both sides of the boundary will review all plans for the development of transboundary reservoirs, and additional requirements may be set before development activities are allowed to begin.
