1 SCOOP Woodford Regional Field Study

2 OVERVIEW The Woodford shale is an organic rich siliceous shale formation of late Devonian and early Mississippian age deposited throughout most of the Anadarko basin of Oklahoma and is the most economically important source rock in the basin. The formation is usually treated as a single depositional group but is occasionally subdivided into three informal members generally described as Upper, Middle, and Lower Woodford. The Woodford becomes deeper and thicker from northeast to southwest following the structure profile of the greater Anadarko basin. Overall thicknesses range from approximately 100 feet or less in the shallowest areas to nearly 1200 feet in the deepest part of the basin. Woodford Shale thermal maturities in the Anadarko basin range from slightly immature (Ro < 0.5%) in the north to very mature (Ro > 4) in south where the depth of the formation plunges to greater than 25,000 feet. This study is focused on the South Central Oklahoma Oil Province (SCOOP) located near the southeastern limits of the Anadarko basin. Several prolific oil fields of commercial significance exist throughout the SCOOP region including the Golden Trend, Sho-Vel-Tum, and Cement fields are likely sourced from the Woodford. Recent development activity has required that further investigation of the areas resources be undertaken at this time. SCOOP Study Well Count 85 Wells Page 2

NULOOK Shale Analysis NUSTIM Geomechanical Analysis NUSTIM Geomechanical Analysis Rock Properties such as: Poisson's Ratio, Young's Modulus, Biot's Constant, pore pressure, overburden pressure, in-situ stress profile descriptions, and brittleness. Young's Modulus is a measure of the stiffness of the rock. It can be obtained from the measurement of dynamic modulus using sonic log measurements. Calculations of Young's Modulus based on the petrophysical properties of an interval are correlated to core or sonic log measurements, allowing for good predictions in intervals where sonic and core data are not available. This property impacts both the NUSTIM fracture and production models. Typical Young's Moduli range from 100,000 to 10,000,000 psi. Poisson's Ratio is a rock property which governs the NUSTIM fracture growth model. It is a component of the stress profile. Poisson's Ratio is defined as the ratio of lateral strain to longitudinal strain. It can be obtained from core measurements or indirectly obtained from sonic log measurements. Calculations of Poisson's Ratio based on the petrophysical properties of an interval are correlated to core or sonic log measurements, allowing for good predictions in intervals where sonic and core data are not available. Poisson's Ratio values typically range from 0.15 to 0.4. Brittleness coefficient (%): Lower values indicate a ductile zone, while higher values indicate a more brittle interval. A brittle zone is more likely to be naturally fractured and to respond positively to waterfrac stimulation techniques. Page 4

7 FIELD STUDIES OVERVIEW NUTECH has combined its expertise with the emerging interest in North American shale plays in order to develop the most detailed regional field studies available to the E&P industry. These studies have been developed through NUTECH s experience and analysis of several thousand wells with core and production data. Each of NUTECH s studies provides insight into the connectivity across the area by simulating geological and Petrophysical property distributions. The results confirm the stratigraphic variability as well as identify and quantify hydrocarbon columns per well and across the study area. NUTECH s management team will provide geological-based input to assist you in decision making on each well, including working closely with your technical personnel in connection with well evaluations and listings. The NULOOK enhanced petrophysical analysis is performed using old electric log information, typically a Spontaneous Potential curve with one or more resistivity curve, or more modern log data, which does not have usable porosity data. The result is consistent with modern complete NULOOK analysis.
