At the center of this opportunity lies the Miocene–Pliocene play fairway within the Tobago Trough – a geological system long proven in neighboring Trinidad and Tobago. Exploration in Grenadian waters has already intersected this play, most notably through the Nutmeg-2 well, which encountered natural gas and confirmed the presence of hydrocarbons in the basin. Regional seismic interpretation further indicates structural and stratigraphic trapping analogous to producing trends in Trinidad and Tobago, reinforcing confidence in the basin’s underlying hydrocarbon system.

Beyond this interval, seismic interpretation has identified additional prospects within deeper Lower Miocene to Eocene horizons, opening the possibility of sizable, previously undrilled resource potential across multiple stacked plays. This layered geology positions Grenada not simply as a single-play gas province, but as a basin with broader structural and stratigraphic opportunity.

Despite encouraging technical indicators, exploration activity in Grenada has historically remained limited. Offshore work has largely been confined to 2D seismic surveys and the single Nutmeg-2 exploration well, leaving much of the country’s roughly 28,500 km² offshore area effectively unexplored. Geological studies dating back to the 1980s have suggested the potential for multi-billion-barrel oil-equivalent resources, yet sparse drilling and limited modern data have kept the basin on the margins of global exploration.

Recent policy and technical initiatives are now shifting that trajectory. The government has established a Hydrocarbons Technical Working Group bringing together international geoscience, engineering and legal expertise to prepare the basin for investment and licensing. Complementing this effort, investors will gain access to historical datasets and updated seismic interpretation through a Virtual Data Room launching in 2026, followed by an invitation-only physical data room ahead of a planned licensing round expected in Q3 2026.

Grenada will present these technical fundamentals at Caribbean Energy Week (CEW) 2026, where the country is scheduled to feature in a dedicated Country Spotlight session designed to connect governments, investors and industry leaders shaping the region’s energy future. The session is expected to showcase geological analogues with neighboring producing basins, early drilling results and the regulatory framework supporting upcoming licensing.

Across the wider Caribbean, offshore discoveries have already transformed national energy trajectories – from Trinidad and Tobago’s gas-driven industrial base to Guyana’s multi-billion-barrel deepwater success. Within this regional context, Grenada represents a frontier basin with credible geological foundations and expanding technical validation.
