Comparative study of the influence of minerals in gas sorption isotherms of thr...

This investigation compares the gas adsorption behaviour and capacity of three bituminous coals from South Africa, of similar rank, by assessing the characteristics of the raw coal, as well as the resulting float and sink fractions (at 1.80 cm3/g) obtained by density separation of crushed coal samples. Calculations were also made to obtain the raw coal gas storage capacity from the weighted contribution of both...

Prerequisites, general criteria and primary studies required in the CoalbedMeth...

The main objectives of this paper are: (i) to review and summarize current concepts of Coalbed Methane (CBM) genesis and storage, (ii) to highlight and present the principal procedures and methodologies concerned with prospecting/exploring of CBM leading to a sequence of basic criteria to be followed at an early stage and, subsequently, during research and exploration, and (iii) to present a list of the most im...

Prospecting for coalbed methane: preliminary investigation into the possibiliti...

The fundamental objetive of this study resides in investigating the potential suitability of spanish coalfields to prospecting natural gas from coal in-situ (Coalbed Methane-CBM). The study was based not only on a literature survey and supplemented by onsite visits and investigations, but also on inhouse research activities. Tree selecting criteria have been defined: 1.1. Existing resources: a figure of 20MT of...

Source rock/dispersed organic matter characterization-TSOP research subcommitee...

Because sedimentary organic matter consists of a diverse mixture of organic components with different properties, a combination of chemical and petrographic results offers the most complete assessment of source rock properties. The primary purpose of this Society for Organic Petrology (TSOP) subcommittee is to contribute to the standardization of kerogen characterization methods. Specific objectives include: (1...

Detection and evaluation of hydrocarbons in source rocks by fluorescence micros...

In pursing the detection of hydrocarbons in sedimentary rocks by conventional petrological methods, an attempt has been made to correlate standard fluorescence parameters with the quality and quantity of hydrocarbons present in crushed rocks embedded in epoxy resin. The capacity of the embedding resin, commonly used in the preparation of petrographic samples, to extract and physically fix hydrocarbons is recogn...
