Permeability evolution in sorbing media. Analogies between organic-rich shale and coal
No full textShale gas reservoirs like coalbed methane (CBM) reservoirs are promising targets for geological sequestration of carbon dioxide (CO2). However, the evolution of permeability in shale reservoirs on injection of CO2 is poorly understood unlike CBM reservoirs. In this study, we report measurements of permeability evolution in shales infiltrated separately by nonsorbing (He) and sorbing (CO2) gases under varying gas pressures and confining stresses. Experiments are completed on Pennsylvanian shales containing both natural and artificial fractures under nonpropped and propped conditions. We use the models for permeability evolution in coal (Journal of Petroleum Science and Engineering, Under Revision) to codify the permeability evolution observed in the shale samples. It is observed that for a naturally fractured shale, the He permeability increases by approximately 15% as effective stress is reduced by increasing the gas pressure from 1 MPa to 6 MPa at constant confining stress of 10 MPa. Conversely, the CO2 permeability reduces by a factor of two under similar conditions. A second core is split with a fine saw to create a smooth artificial fracture and the permeabilities are measured for both nonpropped and propped fractures. The He permeability of a propped artificial fracture is approximately 2- to 3fold that of the nonpropped fracture. The He permeability increases with gas pressure under constant confining stress for both nonpropped and propped cases. However, the CO2 permeability of the propped fracture decreases by between one-half to one-third as the gas pressure increases from 1 to 4 MPa at constant confining stress. Interestingly, the CO2 permeability of nonpropped fracture increases with gas pressure at constant confining stress. The permeability evolution of nonpropped and propped artificial fractures in shale is found to be similar to those observed in coals but the extent of permeability reduction by swelling is much lower in shale due to its lower organic content. Optical profilometry is used to quantify the surface roughness. The changes in surface roughness indicate significant influence of proppant indentation on fracture surface in the shale sample. The trends of permeability evolution on injection of CO2 in coals and shales are found analogous; therefore, the permeability evolution models previously developed for coals are adopted to explain the permeability evolution in shales

Gregory Macalister Mathews (1870–1949) is well known for describing birds with minute differences in morphology as distinct subspecies, many of which were subsequently synonymized. The Berlin Museum received these specimens in an exchange with Baron Lionel Walter Rothschild's (1868–1937) Zoological Museum. The second bird, ZMB 30.4, is a doubtful former syntype. Mathews catalogued this specimen from the Herberton Range in 1910 (Mary LeCroy <i>in litt</i>., September 2005), so he would have been able to use it for the species description. However, he later referred to "Type, Bartlefrere, Queensland." These specimens were not mentioned in Meise's MS.</p>Published as part of <i>Steinheimer, Frank D., 2005, The type specimens of Paradisaeidae, Cnemophilidae and Ptilonorhynchidae (Aves) in the Museum für Naturkunde of the Humboldt-University of Berlin, pp. 1-25 in Zootaxa 1072 (1)</i> on page 5, DOI: 10.11646/zootaxa.1072.1.1, <a href="http://zenodo.org/record/5050709">http://zenodo.org/record/5050709</a>
Labiotermes leptothrix Mathews
No full textLabiotermes leptothrix Mathews Labiotermes leptothrix Mathews, 1977: 208 –210 [imago (Fig. 149, 160), soldier (Fig. 148), enteric valve armature (Pl. 49)] Labiotermes pellisetaceus nomen nudum, Mathews 1977: 201, 207, 259, 262 [figure captions only] Holotype: imago, female (MZSP), examined. Typelocality: Brazil: Mato Grosso, Xavantina. Imago. Described and illustrated by Mathews (1977: 208–209). Soldier (Figs. 6 A–B, 11 F). Described by Mathews (1977: 209). Additional measurements are presented in Table 2. Comparisons. The soldier of L. leptothrix is easily recognizable by the presence of numerous microscopic hairs on the head capsule. However, these hairs are only visible with magnification of 40 X or higher and adequate light. The most similar species are L. longilabius and L. brevilabius, which lack these microscopic hairs and have different labra. Worker (Figs. 6 C–F, 13 F, 14 D, 15 K–L, 16 F). Head capsule and postclypeus with numerous bristles. Pronotum with numerous bristles on anterior lobe and a row of bristles on posterior margin. Mesonotum with a line of bristles on posterior margin. Front coxa with a lateral hump near base. Antenna with 15 articles. Fontanelle large and rounded. Enteric valve with 5 fingerlike ridges of unequal sizes, covered with fine spines. Mixed segment with two elongate mesenteric lobes; large lobe with narrow tip; small lobe about one third the length of the large one. Measurements in Table 3. Comparisons. The worker of L. leptothrix can be recognized by the very large apical teeth on both mandibles and the enteric valve armature, which has 5 ridges. Geographical distribution. L. leptothrix occurs in the northern part of the Cerrado biome (Fig. 21). Most records are from cerrado vegetation, but Mathews (1977: 210) also found it in a valley forest. Remark 1. Mathews (1977: 234, plate 49) states that the enteric valve of L. leptothrix has 6 fingerlike plates (ridges). However, his own illustration shows only 5 ridges. All specimens we examined had 5 ridges, not 6. Remark 2. Labiotermes pellisetaceus is a nomen nudum which appears in figure captions in Mathews (1977), obviously as a result of an error. The association of a name with illustrations alone does not satisfy the requirements of article 13 of the International Code of Zoological Nomenclature (ICZN, 1999). The fact that the original description of L. leptothrix was published in the same book is irrelevant. The name itself should be accompanied by a description or definition that states in words characters that are purported to diferentiate the taxon. This name is not available and therefore is not to be treatead as a real synonym. Material examined BRAZIL. Amazonas. Humaitá: s., w., 01.vii. 2003, G.C. Costa (UnB 4784). Goiás.
