Palinspastic Reconstruction and Forward Modelling

The application of cross-section construction and validation within exploration and production: a discussion

James G. Buchanan

British Gas Exploration and Production Ltd, Thames Valley Park, Reading, Berkshire RG6 1PT, UK

Numerous published studies have shown that cross-section balancing and validation techniques are a powerful method of structural analysis. This paper outlines reasons why cross-section validation also is a valuable methodology within the oil/gas industry.

Cross-section validation is a vehicle of getting analytical rigour into seismic and non-seismic interpretation by testing the section against the rules of structural geology (in particular geometry).

In addition to the analysis of structural traps, cross-section validation can be used in oil or gas sourcing studies, especially in the relative timing of hydrocarbon migration and trap formation/destruction. It is therefore a valuable methodology in both 3D basin analysis and prospect risking/ranking.

Cross-section validation should be an integral part of the petroleum geologist’s tool kit to aid further understanding of the 3D evolution of a basin and basin fluids through time. This technique, when used with other methodologies, such as sequence stratigraphy and basin modelling, allows the interpreter to use all the available data sets to constrain geological models on hydrocarbon prospectivity.
