FIGURE 5 Core Permeability Cross-Section D-D’ of Rex Energy’s ongoing Middagh ASP flood. Locations of older wells with SP data used to develop the model are shown as blue lines and dots, and modern porosity logs are labeled with black numbers. Field Results Rex Energy is reporting a positive response on its Middagh ASP pilot project in the Pennsylvanian Bridgeport B reservoir. Oil response in the 15-acre flood has continued to show an increase in the average oil cut from 1 to 12 percent. Total pattern oil production increased from 16 barrels a day to stabilize within a range of 65-75 bbl/d in the last three months of 2011. Peak oil production rose to 100-plus bbl/d, with some individual wells in the pilot showing oil cuts greater than 20 percent. A second 58-acre pilot (Perkins-Smith) adjacent to and likely in communication with the Middagh pilot has been initiated. Preliminary brine injection is in progress with plans to initiate ASP injection by mid-2012. The response is expected by mid-2013 with peak recovery anticipated by late 2013. Rex Energy is projecting full-scale expansion, with the next step of development being a 351-acre project scheduled to begin in mid-2013. Preliminary development has been initiated in this Delta Unit area located in the southern half of section 32 T4N R12W. Reservoir characterization has a critical role in developing a complex chemical EOR process such as ASP, especially in highly compartmentalized reservoirs that

have greatly enhanced the ability to delineate reservoir characteristics that are necessary to increase the likelihood for successful ASP EOR applications. EOR Target The Bridgeport B sandstones in Section 32 are being targeted because these reservoirs are more compartmentalized than the thick channel fill sandstones in Section 5. These compartmentalized reservoirs are being used in an early phase assessment of ASP flood design and development in a confined area that results in the most effective flood recovery. The success from these Rex Energy-confined reservoir flood designs will be implemented in largerscale floods, such as the 350-acre Delta region in the southern half of Section 32. After developing the geological model, a geocellular model was constructed using the geological data and reservoir geometries as a foundation. This is used to confirm the geologic reservoir model and is required for effective reservoir simulation modeling. The 3-D modeling images are also a valuable visualization tool for evaluating reservoir characteristics such as compartmentalization, porosity, permeability and residual oil saturation. A comprehensive geologic reservoir characterization assessment is essential to develop an effective reservoir simulation model. A simulation model that most precisely portrays the reservoir will increase accuracy of pore volume calculations used for chemical input estimations and oil recovery projections, and can be used for effective flood design. The finalized

geocellular model, located in the northeast quarter of Section 32 and containing permeability, porosity and oil saturation, was then transferred to Rex Energy for use in simulation modeling. The results of the simulation will guide future development of the field for ASP purposes. Figure 6 is a plan view of the Bridgeport B model, showing the outline of the reservoir. The model is 200 acres located in the northeast portion of Section 32 T4N R12W. This porosity model that displays an area where porosity is ≥16 percent. The red box outlines the location
