A vote in France’s Senate could ultimately reshape the competitive and geological landscape of the Guyana-Suriname Basin, with potential implications for both Guyana’s Stabroek-led production story and Suriname’s emerging offshore push.
On January 29, the Senate adopted a member’s bill introduced by Senator Georges Patient – representing the territory of French Guiana – aimed at lifting the ban on hydrocarbon research, exploration and production in France’s overseas territories – a restriction introduced under the 2017 hydrocarbons law.
While the proposal does not immediately change French law, it reopens a question with regional consequences: whether French Guiana’s offshore acreage could once again be evaluated alongside neighboring petroleum systems that have already delivered world-class discoveries in Guyana and Suriname.
Despite an unfavorable opinion from the French government, the bill was adopted by a wide majority, with 227 in favor and 105 against.
To understand the significance of this development, it is necessary to revisit why hydrocarbon exploration was banned in the first place, how French overseas territories came to be included in that ban and what the Senate vote does – and does not – change from a legal standpoint.
In 2017, France introduced a ban on new oil and gas exploration and production licenses under its hydrocarbons law, referred to as the “Hulot Law”, positioning itself as the first country to ban fossil fuel development. The law applied nationally and was primarily motivated by environmental and climate considerations, aligning France’s domestic energy policy with its international climate commitments.
The ban was designed with mainland France in mind, where hydrocarbon production is limited and largely marginal to the national supply. However, the legal framework was later extended to France’s overseas territories, including French Guiana, despite their different geographic, economic, and energy realities.
In French Guiana’s case, the prohibition closed the door on offshore and onshore hydrocarbon exploration before the territory had the opportunity to fully assess its resource potential.
Now, the Senate’s vote has reopened the question of whether the 2017 ban should apply uniformly to France’s overseas territories. The practical answer lies in the balance of powers within France’s legislative system.
France’s Parliament consists of two chambers: the Senate and the National Assembly. Together, they form a single legislative authority. However, they do not have equal power. They can both propose, debate and amend legislation, but the National Assembly, whose members are directly elected, has the final say in adopting laws. The Senate members are indirectly elected and represent territorial interests, including regions, municipalities and overseas territories.
A bill adopted by the Senate does not, on its own, change French law. For a bill to become law, it must also be debated and adopted by the National Assembly. In a case of disagreement between the two, the National Assembly prevails.
The Senate’s adoption of the bill, therefore, marks a legislative step rather than a final decision. Its future will depend on whether the proposal receives sufficient support at the National Assembly.
While French Minister of Overseas Territories Naïma Moutchou expressed support for the bill on the Senate floor, Minister of Ecological Transition Monique Barbut strongly opposed it. “The government has decided to issue a negative opinion on this bill… supporting this bill would make France’s position untenable internationally.”
Senator Patient, who sponsored the bill, said the proposal is intended to address what he described as the uniform application of public policies designed for mainland France without sufficient consideration of the economic and social realities of overseas regions. In a statement following the vote, he said the Senate, as the chamber representing territories, sought to assert a more territorially adapted approach to energy and environmental policy.
Senator Patient stated that the proposal does not call into question France’s climate commitments or environmental objectives. Instead, it argues that the energy transition should be designed in a way that accounts for local conditions and development needs in overseas territories of France.
Now, if the proposal is also adopted by the National Assembly in Paris, the consequences for French Guiana would be significant. The lifting of the ban will allow oil companies to evaluate the territory as part of the broader Guyana-Suriname basin, where recent discoveries have already transformed regional energy dynamics.
In practical terms, this could mean the resumption of geological studies, seismic surveys and data analysis aimed at assessing whether the petroleum systems proven in neighboring blocks, including Guyana’s Stabroek Block and Suriname’s Block 58 trends, extend into French Guiana’s offshore acreage.
That geological continuity, however, remains contested.
In April 2024, CEO of TotalEnergies Patrick Pouyanné, testified before the Senate regarding the company’s energy transition strategy. At that time, he stated, “You didn’t hear much complaint from TotalEnergies when the Hulot Law was passed. There are no hydrocarbons in French Guiana…we found hydrocarbons in Suriname. I can come with the geological maps and explain why the Suriname basin does not extend east of Suriname into French Guiana.”
For observers and stakeholders in the energy sector, understanding where the proposal sits within the legislative process is essential to assessing its importance. In this case, the rules of the game matter as much as the outcome – and, for the moment, the game is still being played.
