The Rioni Basin in West Georgia is an Oligocene foredeep that evolved into a Miocene to Pliocene foreland basin, north of the Achara-Trialeti thrust belt and south of the Greater Caucasus. It extends to the west into the Black Sea. A large number of exploration wildcats have been drilled onshore since the nineteenth century and have led to the discovery of three fields. Exploration was prompted by seeps and restricted to frontal ramp anticlines mapped at surface. No wells have been drilled offshore. Supsa (discovered 1889) contains 29 MMbbl oil in clastic Sarmatian reservoirs. The field has around 50 wells but less than 0.5 MMbbl have been produced. Shromisubani (discovered 1973) contains oil within Maeotian and Pontian clastic reservoirs, Chaladidi oil within Upper Cretaceous chalk. Despite this long and apparently intensive exploration effort, several factors make the basin an exciting target for field redevelopment and further exploration. The quality of existing seismic is very poor both on-and offshore. Reinterpretation of the structure of the fold and thrust belt has suggested the presence of new targets and plays which may be imaged by modern seismic methods. In addition, due to problems associated with central planning, discovered fields have not been optimally developed or even fully appraised. The application of new technology, geological interpretation and investment promises to delineate substantial remaining reserves even after more than one hundred years of exploration.
