Policy Recommendations
• Indonesia should adopt the SPE Resource Classification
and report reserves as proven, probable and possible
• Indonesia should start providing a quantitative
assessment of both contingent resources and prospective
resources
• This information should be published on an annual basis
• Indonesia should carry out its own technical assessment
of prospective resources for CBM and shale gas
• With the activity currently underway in CBM exploration
Indonesia should shortly be able to classify some CBM as
a contingent resource.
