Solid state ¹³C nuclear magnetic resonance (NMR) spectroscopy is used to examine kerogen composition in weathering profiles of the Monterey, Green River, Woodford, and New Albany formations. Techniques include cross polarization (CP) and Bloch decay (BD) spectral acquisition, dipolar dephasing (DD), spin counting, experiments to provide estimates of relaxation times (T₁ρH and T₁H), and proton spin relaxation editing (PSRE). It is demonstrated that CP/MAS (cross polarization/magic angle spinning) spectra obtained on isolated kerogens provide reliable characterization of kerogen composition (compared with BD spectra and whole-rock samples). Highly aliphatic (polymethylenic) kerogens are not appreciably altered during weathering. Aromatic and/or branched aliphatic kerogens accumulate oxidation products and preferentially lose aliphatic relative to aromatic carbon during weathering. No relation is observed between T₁ρH times and either kerogen composition or degree of weathering; T₁H times correlate with aromaticity. Two distinct components within kerogens are discerned by PSRE: one highly aliphatic (largely polymethylenic) component and one mixed aliphatic/aromatic component. During weathering, the highly aliphatic component remains largely unaltered...

This poster was presented at the 2006 Eastern Section American Association of Petroleum Geologists, 35th Annual Meeting, in Buffalo, N.Y., October 8-11, 2006.; The New Albany Shale (Devonian and Mississippian) in Indiana is mostly brownish-black organic-rich shale with lesser greenish-gray shale. The formation is 100 to 140 feet thick in southeastern Indiana and dips and thickens to the southwest into the Illinois Basin, where it attains a thickness of more than 360 feet in Posey County. Gas production from New Albany Shale began in 1885 and drilling activity continued into the 1930s, when interest waned in favor of more lucrative opportunities elsewhere. Renewed activity, driven by higher gas prices, has been brisk since the mid-1990s, witnessed by the completion of more than 400 productive wells. The majority of these wells were drilled in Harrison County, where production typically occurs at depths from 500 to 1,100 feet and production rates generally range from 20 to 450 MCFGPD. In the past 2 years, Daviess County and surrounding areas have become the focus of New Albany exploration after the El Paso Production No. 2-10 Peterson horizontal discovery well was rumored to have tested 1.3 MMCFGPD at an approximate measured depth of 2...

This poster was presented at the Eastern Section American Association of Petroleum Geologists (AAPG) conference in Kalamazoo, Michigan, September 25-29, 2010.; This study investigates kerogen petrography, gas desorption, geochemistry, and micro- and mesoporosity of the New Albany Shale (Devonian-Mississippian) in the eastern part of the Illinois basin. Core analysis from two locations, one in Owen County, Indiana and one in Pike County, Indiana was conducted. The volumes of gas in the locations studied are primarily dependent on total organic carbon (TOC) content and the micropore volume of the shales. Gas origins were assessed using stable isotope geochemistry, whereas maturity assessments utilized both measured and modeled Ro values. Different depths of burial and formation water salinities are likely responsible for dominant origins of the gas in the two locations studied. The shallower Owen County location (415 to 433 m deep) contains significant microbial methane, whereas the Pike County location (832 to 860 m deep) is characterized exclusively by thermogenic gas. Despite differences in the gas origins, the total gas in both locations is similar, reaching up to 2.2 cm3/g (70 scf/ton). The lower thermogenic gas content at the shallower location (probably because of the lower thermal maturity and possibly higher loss of gas related to uplift and leakage via relaxed fractures) is compensated by additional generation of microbial methane most probably stimulated by influx of glacial meltwater causing both brine dilution and microbial inoculation. The characteristics of the shale of the Maquoketa Group (Ordovician) in the Pike County location indicate that the controls on the gas volumes are similar to those in the New Albany Shale.

Preliminary engineering geology investigations have been made of four proposed dam sites and their reservoir areas in the valley of the East Fork of the Muscatatuck River and its tributaries, Big Camp and Big Graham Creeks, in northern Scott County, southern Jennings County, and western Jefferson County, Ind. In this report the geologic column of the area has been divided, according to engineering characteristics, into five units. The bedrock consists of (in ascending order) unit 1, the Osgood Formation and the Laurel Limestone of Silurian age; unit 2, the Waldron Shale and the Louisville Limestone of Silurian age and the Geneva Dolomite and the Jeffersonville Limestone of Devonian age; unit 3~ the North Vernon Limestone of Devonian age; and unit 4~ the Devonian portion of the New Albany Shale. These rocks are overlain at most places by unit 5, the unconsolidated materials that range in character from red residual limestone soils to glacial till. The bedrock formations stratigraphically below the North Vernon Limestone (units 1 and 2) are essentially sound rock and offer few problems to dam and reservoir construction except the possibility of a small amount of leakage. The Jeffersonville Limestone (the top formation of unit 2) includes a gray limestone bed that contains a few solution channels...
