Cooper Basin Deep Coal Play - Resource Assessment

The Deep Coal Consortium is pleased to announce completion of the first systematic review of the volumetric  hydrocarbon potential of the Gidgealpa Group Coal Measures in the deep portions (>3,000 feet) of the Cooper Basin based upon detailed analysis of well data (n=1,300).  The Gidgealpa Group was evaluated in 10 assessment intervals based upon regional well correlation.

The study provides both deterministic and probabilistic estimates of in-place and technically recoverable gas and liquids, and (for the first time) Prospective Resources.  Results are presented in tabular form and as a set of maps for each assessment interval and for the Group.


Low (P90), Median (P50) and High (P10) map realisations were generated for each assessment interval and volumes were aggregated to estimate the Group resource potential.   An example for one interval is shown.

The methods used to calculate the map-based uncertainty in volumetric potential are innovative and discussed in URTEC 198304-MS.


The Deep Coal Play contains world-class volumes of potentially commercial gas and condensate. This volumetric study provides strategic spatial context for decision-making as efforts to commercialise this play accelerate in the months ahead. 


In addition, the data can be used to more fully characterise specific portions of the play, such as company acreage.  The Consortium can provide technical support for such customised analysis.
