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.
