A fundamental problem facing any drilling organization is learning. The geologic environment is never perfectly known, and the organization is never entirely certain of the best way to drill a particular well. This is especially true in areas where development wells do not number in the hundreds. This means that drilling organizations are faced with the challenge of learning how to apply technology better in a partially unknown environment. This paper describes a computer-based management system to make organizational learning a part of the way drilling teams do their everyday business. The system, the drilling management system (DMS), uses commonly available software on IBM-compatible PC’s.
