Geological and economic evaluation (GEE): from present to future

Abstract

Geological and economic assessment (GEA) of new exploration projects is based on an integrated analysis of all uncertainties and risks of its implementation. GEA includes several stages: evaluation the volume of geological resources and probability of success of deposit discovery; production potential of the deposit; design and evaluation of infrastructure solutions; the cost of discovery and development of oil field and finally economic effect of the project realization. Usually GEA-process takes a long time of teamwork and utilizes specialized software which incorporate probabilistic analysis methods. Development of the IT-solutions for complex geological and economic assessment will allow the company to significantly optimize this process. The first step on the way to full automation of GEA became the software for probabilistic geological evaluation Geomate:VEGA developed in Gazpromneft NTC LLC and launched into commercial exploitation in the group of companies Gazprom Neft in 2017.
