ABSTRACT

 The conversion of complex geological maps into representative 3D models is an essential step for accurately simulating subsurface reservoirs. However, this can be a challenging and time-intensive process. The accurate representation of geological structures is crucial for reservoir modeling, as it directly influences predictions of fluid flow and resource estimation. Traditional geological contour maps provide valuable insights, but converting these 2D representations into a detailed 3D structure is a complex and critical task.

The study employed a comprehensive methodology to address the challenge of constructing a dependable geological model from limited sub-surface information. This involved techniques such as grid configuration, digitizing contours, kriging interpolation, and defining reservoir boundaries. The workflow integrated various tools and methodologies to ensure the precision and reliability required for reservoir modeling.

The results of the study demonstrate the successful integration of a geological contour map and advanced modeling techniques to generate a 3D representation of the reservoir in the IZYP field in the Niger Delta region. The developed 3D model accurately captured the subsurface structures and heterogeneities, providing a valuable tool for improved reservoir simulation and fluid flow predictions
