Sediments from Holes 994C, 995A, 997A, and 997B have been investigated for “combined” gases (adsorbed gas and that portion of free gas that has not escaped from the pore volume during core recovery and sample collection and storage), solventextractable organic compounds, and microscopically identifiable organic matter. The soluble materials mainly consist of polar compounds. The saturated hydro...

Time-temperature index (TTI) modeling is used to establish a simple theoretical thermal maturity for Paleozoic strata in central Kansas. These thermal maturation calculations are based on estimates of likely geothermal gradients and best knowledge of the tectonic history of the region, as derived from stratigraphic thicknesses and estimates of erosion at unconformities. Major uncertainties in t...

Abstract In this study the hydrocarbon generation potential of coal and coaly shale samples collected from mines in Attock-Cherat Range Pakistan is optically analytically evaluated. These samples, representing Paleocene Hangu Formation, are analyzed across a range thermal maturity stages to understand their potential. The visual examination maceral type values vitrinite reflectance have been co...

the nayband formation was measured and sampled in parvadeh area, southern tabas city. in this area, this formation has a thickness of 1410 m, dividing into four members, namely gelkan, bidestan, howz-e-sheikh and howz-e-khan. a total 573 samples were treated for palynological analysis, and only 120 samples were productive. a total of 57 miospore taxa and 11 plant macrofossil were encountered. b...
