Abstract

Introduction. Traditionally, uncertainties associated with the net pay volume prediction in the inter-well space contribute to the greatest challenges in the geological & economic assessment. Depending on the specifi c features of productive deposits in the areas being evaluated, it becomes necessary to develop universal algorithms for adapting the calculation process.

Aim. The purpose of this work is to optimize large-scale exploration projects by universalizing fluid-saturated thicknesses multi-variant calculations approaches, depending on the quantity, type, and quality of the initial geological & geophysical information.

Materials and methods. An adaptive integrated algorithm for multi-variant calculations using the Workflow function in geological so ware packages has been developed, which provides for more than 2,500 possible scenarios depending on a variety of factors. The algorithm includes calculations auto-adaptation as well as a specifi c numerical combination for triggering specifi c cycles.

Results. The use of this algorithm allows for the automation and, thus, signifi cant acceleration of the process of multivariate geological assessment of fluid-saturated volumes.

Conclusion. The adaptation of multi-variant calculations increases the large-scale geological exploration projects value at the exploration stage, both in terms of reducing the time & labor required, and in terms of the ability to calculate additional intervals within the allocated time for geological evaluation.
