Abstract

Several years ago ExxonMobil developed a best practice process to evaluate and understand risk in DHIdependent<br>plays. Within this best practice, a robust processing stream, rigorous analysis process, and a<br>calibrated DHI-rating system using both DHI and data quality characteristics were designed. The rating system<br>provides a valuable structure for evaluating DHI quality on a risk analysis basis. The example presented shows<br>how applying best practices can help identify the key risks prior to drilling the first well in a frontier basin in the<br>Norwegian Sea. Using our best practice methodology the main risk identified was low gas saturation (fizzwater),<br>even though no low gas saturated sands were previously encountered in the area. Subsequent drilling<br>confirmed our prediction. In this talk we will summarize our pre-drill analysis and share learnings from the drill<br>well results.
