Turkmenistan expects growth in its natural gas reserves

Turkmenistan's gas and gas condensate reserves can be substantially increased thanks to further geological, geophysical and drilling studies to be carried out on the country’s plain lands, as well as within the West-Turkmen cavity.

This was announced by Taganguly Ilamanov, a candidate of Geological and Mineralogical Sciences, Deputy Director of the Natural Gas Research Institute of the Turkmengas state concern, Neutral Turkmenistan reported.

Ilamanov further said that the strategy of development of the country’s oil and gas industry requires accelerated exploration and development of new prospective areas and fields.

In this regard, attention is paid to the study of geology, lithostratigraphy of gas bearing strata of the Mesozoic platform areas of Turkmenistan and Cenozoic strata of the West-Turkmen cavity, lithology and gas-bearing sediments of Jurassic period in Central Turkmenistan, research of oil and gas paleo-basins.

Complex analysis and detailed processing of geological and geophysical information on the gas fields of central and southeast Turkmenistan are now being conducted. They scientifically defined the exploration in the prospective regions through 2D and 3D seismic surveys and drilling.

Speaking about the Galkynysh field, the world’s second biggest gas field located in the eastern part of Turkmenistan, he said that this field is unique for its geological conditions.

The drilling of the second and third stages of development is being prepared. The research will provide complete information on carbonate rocks and reservoir characterization as a whole, both in separate parts of the field and the cut.

“These data will be of great scientific importance in improving understanding of the geological structure of the Upper Jurassic carbonate complex and, therefore, improve the current estimates of gas reserves and refine the geological model of Galkinish field,” Ilamanov said.

At the time, this natural larder is at an early stage of development, therefore the estimation of reserves is limited to the area covered in the geological model.

However, there is a high probability that the Galkinish field goes beyond these boundaries.

The additional seismic and well surveys will allow to re-estimate gas reserves of the Galkynysh field, while the obtained results will be used for the rational exploitation of this gas-bearing territory.

Turkmenistan has great opportunities for future which lie in exploration and development of oil and natural gas fields, especially Galkynysh, Osman, Minara, Tagtabazar-I, offshore blocks, and the Central Karakum group of fields and construction of gas treatment and processing units at the above-mentioned fields.

According to the data collected by UK’s Gaffney, Cline & Associates, reserves of the Galkynysh, together with reserves of the Yashlar field, are estimated at 26.2 trillion cubic meters of gas and reaches 27.4 trillion cubic meters – together with reserves of the reopened Garakel field.

Turkmenistan, which is rich with oil and gas resources, opened about two hundred oil and gas fields so far. Potential hydrocarbon resources of the country amount to 71.2 billion tons of oil equivalent, of which 53 billion falls on the land, and 18.2 billion tons - on marine areas.

Currently, Turkmenistan delivers gas to Iran and China.
