Shale Gas and the EU Internal Gas Market: Beyond the Hype and Hysteria. CEPS Working Document No. 369, September 2012
No full textThis paper analyses the interplay between shale gas and the EU internal gas market. Drawing on data presented in the 2012 International Energy Agency’s report on unconventional gas and additional scenario analyses performed by the Joint Research Centre, the paper is based on the assumption that shale gas will not fundamentally change the EU’s dependence on foreign gas supplies. It argues that attention should be shifted away from hyping shale gas to completing the internal gas market. Two main reasons are given for this. First, the internal gas market is needed to enable shale gas development in countries where there is political support for shale gas extraction. And second, a well-functioning internal gas market would, arguably, contribute much more to Europe’s security of supply
than domestic shale gas exploitation. This has important implications for the shale gas industry. As it is hard to see how subsidies or exemptions from environmental legislation could be justified, shale gas development in Europe will only go ahead if it proves to be both
economically and environmentally viable. It is thus up to the energy industry to demonstrate that this is the case
Matthew Henry: The Bible, Prayer, and Piety – A Tercentenary Celebration
No full textThe summer of 2014 marked the tercentenary of the death of Matthew Henry (1662–1714), a leading figure among early eighteenth-century Dissenters and author of the six-volume Exposition of the Old and New Testaments (1707–1714/25). This monumental work, which by 1855 had already been published in twenty-five different editions, attempted a peculiarly practical approach to the biblical text and continues to be widely used and readily accessible even today in both print and online versions. The theme of foreign (or ‘strange’) wives and Israelite intermarriage is one which occurs throughout the Hebrew Bible and, accordingly, throughout Matthew Henry’s commentary upon it. Where it appears, the practice of intermarriage is characterized by Henry as (at best) unwise and (at worst) a very real threat to both social and religious cohesion. This essay explores how Henry deals with the issue of ‘strange wives’, why he believes they continue to pose a threat, and (in view of the overall intention of his commentary) what ‘practical observations’ he offers to his reader as a result. In doing so it is argued that Henry’s commentary traces a thematic thread from the ante-diluvian age to the post-exilic period of calamities resulting from mixed marriages between ‘professors of religion’ and their ‘strange wives’
Reservoir Characterization and Chemostratigraphy of the Goddard Shale in the South Central Oklahoma Oil Province
No full textThe Goddard Shale of the South Central Oklahoma Oil Province, or SCOOP, has become a formation of interest in recent years. However, there is a paucity of published information in regards to this formation. Therefore, the purpose of this study is to provide a reservoir characterization of the formation by means of core description of lithofacies, chemostratigraphic trends, chemofacies, mineralogy, and porosity. Additionally, this study sets out to define the appropriate nomenclature for the formation, which has not been defined in a formal sense.
Descriptions and chemostratigraphic work were carried out on two cores taken from the formation. One was taken from its uppermost organic-rich bench, which this study refers to as the Boatwright Shale, and the other core was taken from the lowermost organic-rich bench, which this study refers to as the Velma Shale. Both cores are predominantly siliceous-argillaceous with carbonate content being restricted to debris flows from the inner shelf. Each core contains its own parasequence set with higher-order intervals superimposed, most easily defined by the changes in continental input by means of trace elemental proxies, although each has a different manifestation of the effects of rising sea levels.
In analyzing the porosity of the formation, this study compares three different techniques: 1) FESEM image analysis utilizing ion beam milling, 2) FESEM image analysis utilizing freshly broken shale surfaces, and 3) a method that relies upon calculated matrix density based upon Rock-Eval and XRD mineralogy. Of the three, the broken surfaces technique appears to have produced the most accurate results due to the large margin of error in the calculated density technique and the general lack of inorganic porosity in the ion beam milling technique. Measured porosity values range from 7.04% to 13.11%
Citation expectations: are they realized? Study of the Matthew index for Russian papers published abroad
No full textWe consider the "Matthew effect" in the citation process which leads to reallocation (or misallocation) of the citations received by scientific papers within the same journals. The case when such reallocation correlates with a country where an author works is investigated. Russian papers in chemistry and physics published abroad were examined. We found that in both disciplines in about 60% of journals Russian papers are cited less than average ones. However, if we consider each discipline as a whole, citedness of a Russian paper in physics will be on the average level, while chemistry publications receive about 16% citations less than one may expect from the citedness of the journals where they appear. Moreover, Russian chemistry papers mostly become undercited in the leading journals of the field. Characteristics of a "Matthew index" indicator and its significance for scientometric studies are also discussed
Comprehensive Reservoir Characterization of the Woodford Shale in Parts of Garfield and Kingfisher Counties, Oklahoma
No full textThis research is a comprehensive characterization of the Woodford Shale within an area of six townships and ranges located at the boundary of Garfield and Kingfisher Counties in Oklahoma.
The methods of the Woodford Shale reservoir characterization include: sequence stratigraphy interpretation, well log interpretation, X-ray diffraction (XRD) and X-ray fluorescence (XRF) analysis on drill cuttings, Rock-Eval organic geochemistry analysis and microseismic interpretation.
The interpretation results of these methods provided detailed characteristics of the Woodford Shale. Seven third order parasequences were identified within the Woodford based on the well logs. The lower parasequences were more likely to be deposited where there was a paleo-topographic low, and there is an inverse relationship of thickness between the Woodford and Sylvan Shale. The mineral composition obtained from drill cuttings shows that the Woodford Shale has high clay content mainly composed of illite and kaolinite, moderate quartz content derived both from biogenic radiolaria and detrital quartz. The percentage of quartz highly affects the brittleness of the formation and ultimately affects the efficiency of hydraulic fracturing. From the thin section analyses, there are five types of Woodford Shale cuttings identified based on different mineral composition and internal structure. The chemostratigraphic analysis based on the horizontal well XRF profile defined 12 chemofacies. The 12 chemofacies were interpreted and related to sequence stratigraphy and sea level fluctuations. The XRF datasets are also correlated with XRD-derived mineral data and calculated brittleness. The organic geochemistry aspect indicated that Woodford is an organic-rich shale with high TOC value and it is within the oil thermal maturation window due to the shallower burial depth than the Woodford in the Anadarko Basin.
The microseismic data interpretation of one horizontal well indicates that there is a relationship between the sequence stratigraphic framework and the microseismic event distribution. In the highstand system tract (brittle zone), the fractures are more prone to stay within the target formation and grow horizontally to enhance the fracturing efficiency. When the stimulation occurs within the transgressive system tract (ductile zone), the perforation energy will be absorbed by the formation and reduce the fracturing efficiency. From the image log and microseismic distribution patterns, the local stress field was interpreted. The maximum horizontal stress direction is N80E. To get better fracturing effect in the future, nearby well is should be drilled perpendicular to the maximum horizontal stress direction, or N10W.
Overall, the Woodford Shale in the study area is a high potential and high quality unconventional reservoir for exploration and development. The well placement and fracturing plan design need to consider the sequence stratigraphy and heterogeneity within the reservoir in order to enhance drilling efficiency and hydrocarbon production
Regional variability of Caney Shale elemental composition, mineralogy, and petrophysical properties, Ardmore Basin, Oklahoma
No full textThe Mississippian-age Caney Shale of the Ardmore Basin, Oklahoma, consists of four chemofacies based on geochemical analyses of well drill cuttings. Chemofacies 1 and 3 represent a dominant detrital source into the basin, and chemofacies 2 is associated with periods of shallow-water conditions favorable to carbonate mineral formation. Chemofacies 4 represents intervals that are interpreted to have formed by reducing-bottom water conditions during deposition, with pyrite formation in an anoxic setting. The elemental proxies used to indicate carbonate minerals and detrital fluxes correlate with X-ray diffraction (XRD) derived mineralogical analyses. Based on XRD, the Caney Shale is primarily composed of mixed-clays, quartz, and carbonate minerals. The mixed-clay fraction consists of illite and kaolinite, while the carbonate fraction is composed of calcite and ankerite. These results are also consistent with ρmaa-Umaa mineralogical analysis, constrained by XRD results, which revealed 3 rock types: mixed-clays, quartz, and carbonate. Rock-type models and vertical proportion curves illustrate an abundance of carbonate deposits within the central Ardmore Basin, suggesting a shallow-water environment and likely multiple shorefaces delivering sediment across the basin. A decreasing upward GR log response paired with an increasing upward carbonate abundance can be interpreted as transgressive sequences that correspond to 4 stratigraphic zones within the Caney Shale. Chemofacies also correlate with the transgressive sequences, suggesting that chemofacies are related to deposition. 3D total porosity models show an average porosity of approximately 20% per zone of the Caney Shale, with maximum porosity values of 61% occurring in Zone 4. Brittleness index models show brittleness within the quartz rock type, and greater ductility within the mixed clay rock type. This basin-scale characterization provides an understanding of Caney Shale elemental composition, mineralogy, and petrophysical properties and their regional variability
An Interview with Matthew Kaiser on Competition and Play
No full textAn Interview with Matthew Kaiser on Competition and Play, by Sean Scanlan. Matthew Kaiser, the author of The World in Play: Portraits of a Victorian Concept (Stanford UP, 2012) says that “[c]ompetition is the disease from which modern life suffers,” and that “[c]ompetition is the only cure” for this suffering. This contradictory pairing seems to get at the heart of his thesis: play, as a totalizing, umbrella-like concept, emanates from a host of philosophical, political, and scientific work produced by Victorians who posed many of their ideas of play in sports metaphors, competitive logics, and narratives of struggle. Kaiser goes beyond the dichotomy of competition and play/competition or play, by stating “I’m interested in the totalizing potential of both concepts, the way that play, or competition for that matter, swallows the world whole, becomes in the minds of so many people, the organizing principle of reality, whether of culture or nature or consciousness, or of all three.
