Prospecting and exploration work in the coastal zone of the Caspian Sea Southwestern Turkmenistan


28 March 2022

Divisions of the State Corporation «Türkmengeologiýa» are successfully implementing projects to search for new areas promising for oil and gas in the coastal zone of the Caspian Sea, as well as exploration and additional exploration at already identified fields. As the chief geologist of the corporation Dovletgeldi Meredov explained, for these purposes, a significant potential of the country's geological industry is involved, in particular, modern seismic and drilling equipment and technologies that allow geologists to speed up and improve the study of subsoil.

At present, specialists of the Balkan geophysical expedition of the State Corporation «Türkmengeologiýa» are conducting 2D, 3D seismic exploration and gravimetric work in the Gogerendag-Ekerem gas and oil region of this zone. According to the Decree of the President of Turkmenistan, a contract was signed between the State Corporation «Türkmengeologiýa» and the company «Yug-Neftegaz Private Limited» to conduct 3D seismic surveys in the eastern part of the Goturdepe field, and 2D seismic surveys - in the South Burun area of the Pribalhanskiy oil and gas region. Works in these difficult areas of the coastal zone, which are scheduled to begin this year, will open up new prospects for further exploration of gas and oil-bearing areas.

In the coastal zone of the Caspian Sea, the expeditions «Balkannebitgazgözleg», «Lebapnebitgazgözleg» and «Marynebitgazgözleg» of the State Corporation «Türkmengeologiýa» are implementing plans for prospecting and exploratory drilling of deep wells for oil and gas. The purpose of these works is the additional exploration of the lower parts of the Pliocene red-colored deposits, the search (additional exploration) of the Miocene, and in the future - the direction of drilling operations to deeper Mesozoic horizons.

Currently, these expeditions are drilling in the Gogerendag-Ekerem gas and oil region in the areas of Akpatlauk, Keymir, Ekerem, Gamyshlyja, West Korpeje, Mashad, Garadashly; in the Gyzylgum gas and oil region on the areas of Ordekli and Uzynada; in the Balkan oil and gas region on the areas of North Goturdepe, Barsagelmez and South Kelkor. It should be noted that exploration drilling of deep wells in the areas of the latter area is carried out based on the results of previously conducted 2D and 3D seismic surveys by the above-mentioned company.

The deep drilling expeditions of the State Concern «Türkmengeologiýa» have so far begun the construction of one prospecting (№ 19a) and two exploration (№ 7a, № 242) wells at the North Goturdepe field. As a result of the development of a prospecting well, a commercial oil inflow was obtained. It has been put into operation, drilling of exploratory wells continues. The construction of three prospecting (№ 8, № 11, № 15) and three exploration (№ 10,

№ 13, № 16) wells has begun at the Uzynada field. As a result of the development of wells № 8, № 10 and № 13, industrial inflows of oil and gas condensate mixture were obtained and put into operation, the rest are still in drilling.

It is expected that prospecting and exploration of areas and fields in this zone will provide an additional increase in oil and gas condensate reserves.
