Geohazards and pore pressure prediction, the dual topics of this month's special section, are two of the critical geoscience activities regularly performed in virtually all predrill evaluation programs. The first of these, geohazards, involves acquisition, processing, and interpretation of geophysical data specifically designed to characterize the shallow subsurface in fine detail in order to identify drilling hazards—in simplest terms, geohazards assessment points the way to the safest location to drill. The second of these, pore-pressure prediction, employs geophysical data to develop an accurate profile of pore pressure in the entire section through which a well will be drilled (from KB to TD, if you will)—in simplest terms, pore-pressure prediction points the way to drilling a well safely and in the most cost-effective manner. Certainly we can't do without either of these two tasks being completed in timely fashion and with no less than the greatest possible accuracy, of course always being mindful of the need to properly represent the uncertainty inherent in both tasks. As drilling reaches to greater and greater depths in less and less hospitable settings, we're gaining an ever-increasing appreciation for the importance of geophysical data and analyses in these two activities.
