INTERNAL AND EXTERNAL INSPECTION OF 3D GEOLOGICAL MODEL CONSTRUCTION QUALITY

The relevance of this paper is justified by the fact that the authors turn their attention to the problem of building geological models, which are constructed in conditions of an uneven observation grid (drilled wells), where direct measurements of geological and geophysical parameters are conducted. This leads to a multivariance of construction, and the geological models themselves have significant errors and uncertainties, starting from the input data. Accordingly, in geological modeling, it is necessary to involve the entire array of available primary geological and geophysical data, a priori and indirect information, and use various construction algorithms. The results of geological modeling must pass qualitative and quantitative review. In the course of the study, an assessment was made of the quality of the constructed three-dimensional geological model, which was confirmed after an external verification.
