Oman’s Ministry of Energy and Minerals has announced a competitive bidding round for oil and gas exploration in three key concession areas: Block 43A, Block 66 and Block 36.
Interested investors are required to sign a confidentiality agreement to access technical data and receive a process letter that outlines bidding timelines and requirements.

The bidding process will follow a one-stage format, with due diligence preceding the final proposal submission.
Block 43A, covering 6,920km² in the Buraimi area, offers a geologically diverse prospect with inner and outer thrust structures linked to ophiolite formations and a potential foreland basin, according to the Oman Observer.
The existence of multiple play systems such as the Thamama, Wasia and Pabdeh formations points to significant potential for exploration.
The strategic location of Block 43A near proven fields in the United Arab Emirates further increases its attractiveness, the Omani publication said.
Hydrocarbon seepages have been found, confirming an active petroleum system. However, a previous well, Jabel Sumeini-1, did not reach its target, leaving scope for new companies to explore.
Block 66 on the eastern flank of the Rub al Khali Basin covers 4,898km² and is located close to producing fields.
The block offers potential extensions from nearby areas, which is said to make it a promising opportunity for companies with local expertise.
A dataset including multi-vintage 2D and 3D seismic surveys supports exploration efforts in Block 66.
Furthermore, well logs, pressure-volume-temperature reports and core data from two wells provide a technical foundation for bidders.
Block 36 in the Ghudun Basin is the largest of the three at 18,557km², and is part of the broader Rub al Khali region.
This block is notable for having a confirmed working petroleum system, with previous well tests showing gas flows to the surface.
Block 36’s primary targets include conventional sandstones and unconventional Silurian hot shale, which helps minimise hydrocarbon charging risks.
The use of 2D seismic data further supports risk reduction in exploration.
In September, Oman entered into a concession agreement with Daleel Petroleum Company to boost oil and gas exploration and development in Concession Area No. 15 of Al Dhahirah Governorate.
