Enhanced Reservoir Characterization and Well Performance with Integration of Static and Dynamic Data
Reservoirs can exhibit heterogeneity in terms of porosity, permeability, in shaly sands and in carbonates along with fractures, vugs, including wettability. This heterogeneity affects the well evaluation, horizontal well placement and performance estimation that would be crucial for completion, testing and reservoir management decisions.
This presentation will discuss a methodology for reservoir characterization, geological modeling, and well performance prediction by integrating a complete suite of petrophysical and pressure transient test data to build a detailed geological reservoir model with permeability anisotropy.
Production logging has traditionally been used for problem well diagnosis and flow profile in vertical wells and increasingly in horizontal wells in the recent years. It will be shown how the methodologies and the field examples of horizontal production logging can reveal the heterogeneities and aid to reservoir characterization with the integration of numerical Near Wellbore Modeling (NWM) and the production logging in a multilateral well to obtain layer permeabilities. Production logging also becomes crucial for the diagnostic of fractures, spatially distributed. Several field examples of comprehensive production logs with the analysis will be shown with examples.
Multi well comprehensive static and dynamic data integration is also shown to evaluate water sweep, diagnosing reservoir dynamic performance of heterogeneous reservoirs in a mixed salinity environment.
