The Bulla-Deniz field is located in the northern part of Baku archipelago, 80 km south of Baku, 22-23 km from the Alat Bay and 12-15 km south-east of Bulla Island. Tectonically, the structure is a large brachyanticline fold extending toward north-west and south-east with a 27-km length, 9-km width, and 1400 m altitude.
The depth of sea in the field’s area varies between 17-30 m and more. The seafloor is sloping and falling toward south-east. The rise was discovered in 1951 as a result of seismic surveys. Its oil and gas content was discovered in 1973. The field’s average output was 200 tons of condensate and 1 million m3 of gas per day during the test period.
As of the 1st of January 2024, 111 wells have been drilled in the Bulla-Deniz field, 56 of them were abandoned during their drilling and 19 after their exploitation. As of the 1st of January 2024, 12 wells, including 11 gas and condensate wells and 1 oil well are in operation. The main objects of development are the V, VII and VIII of the Productive Formation Layer, as well as the Girmaki Ustu Gilli horizons. The wells are developed by the gush method.
In 2022 2D seismic job was conducted on Bulla-Deniz field to improve the understanding of structure and reservoir properties on productive zones.
The hydrocarbons consist of 12-18% alkanes, 5-7% resin, 0.1-0.31% sulfur, 0.72-1.5% asphaltene.
