f The Value Statement for Applying a Fully Quantitative Approach to Play Mapping

We will show the impact upon real time decision- making of understanding the chance dependencies between prospects, particularly in undrilled or lightly drilled geologic plays. The impact of potential success upon a family of undrilled prospects is often not fully understood or appreciated. GIS technology, along with consistent play mapping using a fully quantified approach (including splitting of chance in to play and prospect components) sometimes reveals that the optimal drilling inventory is not being selected to maximize potential volumes and value.
