Summary:
This paper will examine the principal causes of dry holes and will present a two-part strategy that companies can implement to reduce the number of dry holes they drill . Conducting pre-drill audits can reduce your dry holes by 25 to 50% Studies have shown that approximately half of the dry holes that were drilled were dry due to failure of the trap or seal Audits of the maps that were the basis for drilling the well indicate that the majority of wells attributed to trap or seal failure were actually drilled on invalid structure maps Conducting regional reviews or mentoring sessions can further reduce your dry holes Although it will be virtually impossible to eliminate all dry holes, conducting regional reviews or conducting mentoring sessions with your interpreters will hold them accountable for understanding the petroleum system. Mentoring sessions allow your staff to benefit from the knowledge of experts who can bring a fresh perspective and new insights to help your interpreters better understand of the petroleum system, and improve their maps and evaluations, helping you reduce risk and improving your exploration drilling success.
