advanced technologies to enhance the economics of improved oil recovery (IOR) projects in lower quality Shallow Shelf Carbonate (SSC) reservoirs, resulting in recovery of additional oil that would otherwise be left in the reservoir a t project abandonment. Accurate reservoir description is critical t o the effective evaluation and efficient design of IOR projects in the heterogeneous SSC reservoirs. Therefore, the majority of Budget Period 1 was devoted t o reservoir characterization. Technologies being demonstrated include: 1.Advanced petrophysics 2.Three dimensional (3-D) seismic 3.Cross-well bore tomography 4.Advanced reservoir simulation 5.Carbon dioxide (CO,) stimulation treatments 6.Hydraulic fracturing design and monitoring 7.Mobility control agent
