Characterization of Fractured Reservoirs

Complex fracture networks

Most carbonate reservoirs are naturally fractured and contain fractures that can range from isolated microscopic fissures to kilometer-long structures called fracture swarms or corridors. The fractures create complex paths for hydrocarbons and other fluids which impact reservoir characterization, production performance, and ultimate recovery.

Development of fractured reservoir models

Our flexible workflow helps to identify fracture corridors and model fracture networks. We combine our patented FCM Fracture Cluster Mapping workflow—used to detect and locate fluid highways in the reservoir—with discrete fracture network modeling (DFN) in Petrel software, Q-Technology services, formation testing tools (MDT Modular Formation Dynamics Tester), and borehole image logs (FMI Fullbore Formation MicroImager, OBMI Oil-Base MicroImager, UBI Ultrasonic Borehole Imager and Sonic Scanner Acoustic Scanning Platform). The result: a single unified reservoir model of your fracture network.

A unified representation of the reservoir

Using the discrete fracture network (DFN) approach, Petrel software integrates information from a wide range of sources including 2D and 3D seismic surveys, maps, outcrops, reservoir geomechanics, well logs, well tests, and flow logs.

The model is fed into ECLIPSE reservoir simulation software which quickly and accurately models fluid flow in the reservoir to compare the effectiveness of various production strategies.
