The north-to-south cross-section BB’ shows channel fill sandstone and nonchannel fill tidally influenced sandstone deposits in the Bridgeport A and B intervals from Section 32 T4N R12W to Section 5 T3N R12W. This cross-section connects the 1980s Maraflood pilot and a recently completed ASP pilot in the channel fill sandstone in Section 5 with the tidally influenced sandstone deposit of the Bridgeport B in Section 32, where ASP flood development is in progress. Depositional Environment Sandstones in Section 5 T3N R12W initially were deposited in a fluvial channel, but continuous transgression led to a change in the environment to tide-influenced coastal and estuarine. Thick sandstones in Section 5 were deposited initially in an incised channel with the lower erosive contact, tabular cross-bedding and indistinct zones being part of the fluvial facies. Sea level transgression occurred during sedimentation within the incised channel, resulting in a change in facies from fluvial to coastal marine-estuarine sandstone deposition. The thick sandstone body in Section 5 becomes more ripple bedded with flaser and lenticular bedding near the top, indicating the transition from fluvial facies to coastal/estuarine facies. The abundance of replaced plant material and spores in the lower fluvial facies of the Section 5 sandstone may indicate that the muddy area surrounding the estuary was a lycopod swamp. As the sea level continued to rise, the incised channel widened upward until the estuary finally overran the banks of the channel and embayed the entire area of interest. The thinner sandstone reservoirs in the Bridgeport B interval of Section 32 T4N R12W were deposited in a tidally influenced coastal/estuarine environment. These sandstones are finer-grained and more compacted, and therefore, less porous and permeable than the channel fill reservoir sandstones in Section 5 T3N R12W. Tidal flat, intertidal flat, tidal sand bars and tidal estuarine deposits are located in Section 32. Tidal indicators in the sandstone in Section 32 include ripple bedding, flaser and lenticular bedding, tidal rhythmites and tidal couplets. Some burrowing trace fossils also can be observed. Many of these features are also observed in the uppermost portions of the channel fill sequence in Section 5. Several still stand and channel fill episodes are observed in Bridgeport units in the area of interest. The complexity of this depositional system illustrates the need for FIGURE 4 Cross-Section B-B’ Showing Relationship of Pennsylvanian-Age Bridgeport B Across Sections 32 and 5

detailed mapping of individual sandstone reservoirs, and also explains the high degree of variability in reservoir characteristics and geometries over a small area. Understanding this complexity is necessary for successful EOR development. Reservoir Mapping An isopach map of the net sandstone of the Bridgeport B in Section 32 T4N R12W and the thick correlative Bridgeport channel sandstones in Section 5T 3N R12W are shown Figure 2. As illustrated in the B-B’ cross-section in Figure 4, the Bridgeport B in Section 32 occupies the same stratigraphic position as the thick sandstone in Section 5. In Section 32 T4N R12W, the Bridgeport Sandstone is mapped with a two-foot contour interval with the warmer colors representing thicker sandstone (Figure 2). In Section 5 T3N R12W, the Bridgeport Sandstone is mapped using a 10-foot contour interval with the warmer colors representing thicker sandstone. Reservoir sandstone in the northern half of Section 32 trends east-to-west, and while the sandstone in the southern half of the section takes on a triangular shape, the overall trend is predominately east-to-west. This triangular Bridgeport B region is bounded by two thick sandstone bodies that trend into Section 5 T3N R12W from the northeast and northwest, and converge in the southern part of the section. Thicknesses of these blocky sandstones range up to ≈170 feet. These thick sandstone bodies that appear correlative to the Bridgeport B are actually

channel fill deposits that are related to a sea level drop and erosion of the Bridgeport B sequence, following deposition of the Bridgeport B and are, therefore, younger reservoir strata than the Bridgeport B reservoirs. This sequence stratigraphic complexity is prevalent throughout the Pennsylvanian rock section in the Lawrence Field, and is a reservoir characteristic component that must be understood for effective ASP implementation. A cross-section grid was constructed in the eastern part of Section 5 T3N R12W using all available wells with core-measured porosity and permeability values. Most of the core-measured porosity and permeability values are from thick channel fill sandstones. This is the same area as the 1980s Maraflood pilot and the recently completed ASP pilot. The cross-section D-D’ in Figure 5 shows core permeability values interpolated between the wells, indicating the presence of flow units in the sandstones with higher permeability and porosity. Warmer colors in the right section are areas of higher permeability (600 mD) and cool colors are areas of lower permeability. These cross-sections show some well-to-well continuity of very high permeability and porosity values, indicating a strong likelihood of channelized flow in this reservoir unit. It is difficult to correlate preferential flow units within the channel facies reservoirs with standard mapping techniques using the older-style spontaneous potential (SP)/electric logs that are principally available throughout Lawrence Field.
