Economic efficiency, cost control, and productivity enhancement are strong themes in the petroleum industry as the decade of the 90s emerges. Multidisciplinary teams are being used successfully to address fundamental issues impacting the profitability of all kinds of projects. It is generally accepted that computer hardware and software contribute to enhanced productivity, which in turn, tends to maximize profitability.

Two major barriers to the use of software are skepticism and lack of functionality. The potential software user wants to know precisely what he or she can expect to gain before making a commitment to learn a program. Potential users also want functionality which automatically leads them into the investigative and design aspects of a particular problem. Software products such as word processors, spreadsheets, and graphics packages greatly assist individuals and teams engaged in the operational aspects of problem solving, including data collection and reporting. However, these software products are generally designed to facilitate business communication, hence they lack the specific functionality required to investigate technical problems in a cost-effective manner.

One technical problem which often appears in a multidisciplinary setting is the issue of pore pressure and fracture gradient analysis. Pore pressure regimes in the subsurface greatly affect drilling and completion designs, well costs, and prospect or project economics. Pore pressures can be analyzed in several ways.1-10  One of the most reliable technique is based on well log data1-5  and this is the method preferred by many drilling engineers and explorationists.
