New Method for Predicting Production Boosts Accuracy for Carbonate Reservoirs

The widely developed karst caves and fractures in carbonate reservoirs result in strong spatial heterogeneity. Consequently, the parameters obtained from cores and numerical simulation are limited in their ability to reflect the production possibility of the entire reservoir. To solve this problem, this paper proposes a new method of economic prediction on the basis of expert library and oilfield databases. The method takes into account geological factors and the effect of production factors on the economic prediction.

Introduction

The key parameters used for the economic prediction of a carbonate reservoir include well spacing, oil production, and annual decline rate.
