Eastern onshore side of the South Caspian Basin-prospects for oil and gas exploration (petroleum exploration) of carbonate deposits of the Upper Jurassic-Neocomian

Abstract

For the South Caspian Oil and Gas Bearing Province, the conclusion is made that the Pliocene productivity is predominant in the western part of the province and that the oil and gas prospects in the Mesozoic for the eastern onshore part are a priority. A retrospective analytical review of geological and geophysical data and published materials on the Mesozoic of SouthWest Turkmenistan has been accomplished, it revealed the low efficiency of the performed seismic and drilling works during exploration and evaluation of relatively complex Mesozoic targets. Massive resumption of seismic surveys and appraisal drilling of modern level in the priority areas and targets involving leading Russian companies is proposed. For some areas, a new improved estimation of potential gas resources is provided. The example of modern, highly efficient supplementary exploration of a small Pliocene gas and oil field, West Cheleken, is presented which turned this field into a major one in term of reserves. A first version of this review has been published in Russian (Melikhov et al., 2021). The review is dedicated to the memory of the outstanding Turkmenistan petroleum geologist M.A. Ashirmamedov.
