Integrated Petrophysical Approach Fast-tracks Development and Results from a Heavy-Oil Reservoir in Trinidad

摘要

In planning EOR projects, teams must use all available and affordable resources to optimize results and economize on design. EOR projects are capital intensive and hence modeling the reservoir is of paramount importance before simulation and forecasting begins. Unavailability of seismic data must be substituted by core and log data to prove sand continuity, structure and stratigraphy. The conventional practice of mapping sand facies is important for depositional understanding but for EOR projects it is the flood designer's interest to have flow units mapped. This paper incorporates an existing method, used and proven, early in the life of a wide array of reservoirs, together with revised and new concepts in conducting analysis on shallow heavy oil reservoirs. The use of the core data, log data, Winland35 equation, together with Stratigraphic Modified Lorenz plots have reduced uncertainties and have introduced more confidence in forecasting. The end products are flow units with assigned reservoir properties, to be used in simulation and smarter field development.
