The Kyzyloi Field - Dry Gas Development

The Kyzyloi Production Licence and Contract covers an area of 70,967 acres (287.2 square km).

 

Kyzyloi is a shallow gas field containing sweet (no sulphur) natural gas (~97% methane) in sandstones of Paleogene age at depths up to approximately 2,000 ft (610 m).  The field is well defined both on Soviet–era seismic data and on more recent data shot by the JNOC in 1995 to 1996, and can be clearly seen as amplitude anomalies or bright spots on this data.  The field was first discovered in 1966, and several wells were drilled both to test and delineate the deposit, which is interpreted as being a simple anticlinal structure with sand pinch–out to the north and west. 

Previous drilling has left several suspended wells on the field, which were drilled but not fully tested or completed.  BN Munai ("BNM"), the 100% subsidiary of Tethys, has now re–entered five wells and carried out production tests to ascertain gas produceability and firm–up reserves.  One well was tested prior to BNM’s involvement.  Aggregate gas production from the wells tested to date has exceeded 24 MMcf/d (680 Mcm/d).  These wells, together with an additional well yet to be tested, form the basis for the initial development of the Kyzyloi Field. 

 

In addition, during the exploration drilling program carried out in 2005 by BNM, the Akkulka AKK05 exploration well encountered gas in two sandstone horizons, in the Kyzyloi Sandstones and the Bozoi Sandstones, and was tested from the Kyzyloi Sandstone interval at rates of up to 7.9 MMcf/d (224 Mcm/d) of dry gas. The results of this well and seismic mapping indicate that this well has proved a northeasterly extension of the Kyzyloi Field and this area, now named North–East Kyzyloi, will be included in the initial Kyzyloi development.

The McDaniel Reserve Report estimates net proved plus probable economically recoverable reserves of approximately 50.04 Bcf (1.42 Bcm) for the Kyzyloi Field, including North–East Kyzyloi.

A 32 mile (51 km) 325 mm diameter pipeline and compressor station is currently being constructed to tie–in the development to the major Bukhara–Urals trunkline and first gas production is expected in the second half of 2007, at an initial planned gas rate of approximately 22 MMcf/d (625 Mcm/d).
