1.2.2.2.5 Argyle, Kenya, Lauren coal seam gas fields

The combined Argyle-Kenya gas field is 25 km south-west of Chinchilla in the central Walloon fairway (Miningoilgas, 2014c) and extends over PL 179, 180, 228 and 229, as indicated in Figure 10. The Argyle and Kenya gas fields have a total of about120 development wells (GPinfo, 2014) with a mean daily production rate of 149 TJ reported for the March 2014 quarter (Origin Energy, 2014). The tenure PL 180 also includes the Lauren gas field, which extends into PL 263 (see Figure 10). This gas field currently has approximately 110 development wells (as of October 2014) (GPinfo, 2014).

The 2P reserves of the five petroleum leases in which these three gas fields are located are summarised in Table 4. Their combined 2P reserves are 2669 PJ as of 31 December 2013 (DNRM, 2014d). The majority stakeholders of these tenures are APLNG, QGC, and Coal Seam Gas Company Pty Ltd (CNOOC) with QGC acting as the operator. The target coals are the Walloon Coal Measures. Gas processing occurs at the Windibri Gas Processing Facility, which has a capacity of 144 TJ/day, and the Kenya Central Gas Processing Facility, which has a capacity of 180 TJ/day (QGC feedback, received 15 August 2014). The processed gas is supplied to Incitec Pivot’s Ammonia Plant (74 PJ over 10 years) (Miningoilgas, 2014c) and QGC’s 140 MW Condamine Power Station (Australian Mining Link, 2013a).
