Comprehensive Reservoir Characterization Through Data Integration and Numerical Single Well Simulation

摘要

Reservoir heterogeneity, single and multi-phase formation properties dictate well productivity, reservoir performance and management strategy. Cores, open hole logs, formation testers, pressure transient tests, and production logs are usually used to estimate the reservoir heterogeneity and quantify the single and multi-phase formation properties. The results obtained from these techniques are utilized in reservoir simulations to assess the reservoir performance and optimize the reservoir production. A common limitation of these measurement techniques is that they do not provide two-dimensional spatial information of reservoir characteristics. For example, cores and logs have excellent vertical resolutions, but very small lateral radii of investigation, and the pressure transient tests have a large lateral radius of investigation, but very poor vertical resolution. Directly using the results from these measurements in reservoir simulations is difficult because of scale mismatch between the measurements and the requirements in a typical simulation model. Constructing an appropriate simulation model requires rescaling the data, and that may introduce significant uncertainties.
