Analysis
PETRONAS's September 11 release reports an Estuary small-field contract award and enhanced seismic-data handover for Mutiara. Its internal dateline is September 9. Better information can support development decisions, but receiving data alone proves neither commercial success nor immediate economic value. The independent decision tree here uses hypothetical figures, not field valuations or measured seismic accuracy.
Assume development yields a net USD 20 million if successful and loses USD 10 million otherwise, with a subjective success probability of 40%. Expected payoff is USD 2 million; abstaining gives zero, so development is the baseline choice. Assume an unvalidated binary appraisal test with sensitivity 80% and specificity 90%. Positive results occur with probability 38%; success probabilities conditional on positive and negative results are 84.2105% and 12.9032%.
Under these assumptions, development after a negative result has a negative expected payoff, so develop only after positive results. The unconditional payoff before test cost is 0.32 × USD 20 million minus 0.06 × USD 10 million, or USD 5.8 million. Subtracting an assumed USD 1.5 million upfront test cost gives USD 4.3 million, an improvement of USD 2.3 million over the baseline. Test costs of USD 1 million and USD 2 million instead give USD 4.8 million and USD 3.8 million.
Perfect information would produce expected payoff of USD 8 million before its unknown cost, implying a maximum information value of USD 6 million above baseline. This model excludes discounting, taxes and portfolio effects. No independent dataset validates its probabilities; actual appraisal evidence, costs and decision alternatives would be needed before applying it to a project.
