This document outlines the standard workflow for reservoir modeling which involves geological and geophysical interpretation, petrophysics analysis, static and dynamic modeling, and history matching to optimize development and operating strategies. The workflow includes data collection, seismic and well data integration, building geo-frameworks, facies and petrophysical modeling, volumetric calculations, simulation gridding, and history matching to forecast recovery and estimate reserves. The goal is to enable economic and management decisions, develop operating plans, understand recovery mechanisms, and optimize future well locations and production.
