Summary
The authors, of the Institute of Geology and Exploration of Oil and Gas Fields (IGIRNIGM), compare the condensate content of reservoir gas with the gas factor, reservoir pressure and reservoir temperature in the gas-condensate fields of the Ispanly-Chandyr uplift, in Jurassic carbonate and terrigenous rocks of the Bukhara–Khiva region.
Their table lists, well by well, the test intervals, reservoir pressure, reservoir temperature, potential condensate content, gas factor and condensate density for twenty fields, from Kalandar and Chandyr to Shoda and Jebe. The tested intervals lie at 2,056–2,859 m; reservoir pressures are 19.23–32.8 MPa and reservoir temperatures 73–111.8 °C.
Condensate content falls as the gas factor rises and rises with reservoir pressure and temperature. Pure gas-condensate fields (West Kokchi, Kalandar, Chandyr and Gavana) lie at 19–24 MPa and 78–91 °C, while oil-gas-condensate fields (South Kemachi, Marjon, Sharqiy Ispanly, Darbaza-Yangi Darbaza, West Kruk and Kruk) lie at 23–31 MPa and 91–112 °C.
