LOCATING NEW HYDROCARBON FIELDS AND PREDICTING RESERVOIR PERFORMANCE FROM HYDROCARBON MIGRATION

摘要

A data processing system is provided which determines the migration of oil and gas by a basin simulation section and predicts future reservoir performance from current reservoir production measures. The data processing system provides more accurate reservoir rock and fluid property distribution in reservoir locations between well locations where such attributes cannot be measured. The data processing system operates based on physical realities captured -rom migration by the basin simulation section. The data processing system differs from conventional methods, which use measurements obtained at the wells and interpolate between for regions between the wells using statistical techniques. Results from the data processing system shed more light into reservoir discontinuities among the wells, and yield better distribution of hydrogen sulfide, tar zones (Heavy Oil) within the reservoir. More accurate initial fluid and rock property distribution within the reservoir in a reservoir model obtained with the data processing system also improves production forecasting accuracy for hydrocarbon reservoirs by the reservoir simulation section.
