PRESEM is a computer aided field development training system used in the Petroleum Enginering postgraduate and final year undergraduate courses at Imperial College.

PRESEM provides an integration of many of the activities which go into field development from drilling to the design of surface facilities, economic forecasting of pre performance and application to regulatory authorities.

The core of the PRESEM system consists of a data base which is generated by the system supervisor through a menu driven suite of programs simulating the properties of a given or hypothetical oil field. The data base contains the geological description of the reservoir, rock and fluid properties, presented as mud and electrical logs, RFT and production test data, core and PVT analyses. These vary in accordance with the depth and location of the exploration wells chosen by the user with reference to the formation top surface map.

PRESEM also contains many auxilary programs including Schlumberger type log plotting, log-interpretation, pressure analysis, phase package for separator design, reserves estimates by Monte-Carlo analysis and economic feasibility analysis.

The paper describes the basic features of PRESEM and presents a case study.
