Tenge is an oil and gas condensate field located in the Mangistau region of Kazakhstan , 8 km south of Zhanaozen . The field was discovered in 1964.
Productive sediments 700 m thick (1640–2340 m) cover the stratigraphic range from the Callovian tier of the Upper Jurassic (XIII horizon) to the Allenian tier of the Middle Jurassic (XXIII). The horizons are lithologically represented by the interbedding of strata of sandstones, siltstones and clays.
10 productive horizons were established: gas condensate - 7 and gas condensate - with oil rims - 3. Almost all deposits are reservoir and vaulted.
Low-sulfur oils (0.06 - 0.2%), highly paraffin (22.7 - 25.5%). The content of resins and asphaltenes is 3.9-10.2% and 1.4-3.4%, respectively. The yield of light fractions up to 300 ° C is 27.5%.
Gases of gas condensate deposits are light. The share of heavy hydrocarbons in them is 6.6 - 9%, methane 86-91.7%, nitrogen (0.45 - 2.55%), carbon dioxide (0.3 - 3.2%), hydrogen (0, 2-4.9%), helium, inert gases.
