Determining the depositional pattern by resistivity–seismic inversion for the aquifer system of Maira area,Pakistan 总被引:1,自引:0,他引:1
Velocity and density measured in a well are crucial for synthetic seismic generation which is, in turn, a key to interpreting
real seismic amplitude in terms of lithology, porosity and fluid content. Investigations made in the water wells usually consist
of spontaneous potential, resistivity long and short normal, point resistivity and gamma ray logs. The sonic logs are not
available because these are usually run in the wells drilled for hydrocarbons. To generate the synthetic seismograms, sonic
and density logs are required, which are useful to precisely mark the lithology contacts and formation tops. An attempt has
been made to interpret the subsurface soil of the aquifer system by means of resistivity to seismic inversion. For this purpose,
resistivity logs and surface resistivity sounding were used and the resistivity logs were converted to sonic logs whereas
surface resistivity sounding data transformed into seismic curves. The converted sonic logs and the surface seismic curves
were then used to generate synthetic seismograms. With the utilization of these synthetic seismograms, pseudo-seismic sections
have been developed. Subsurface lithologies encountered in wells exhibit different velocities and densities. The reflection
patterns were marked by using amplitude standout, character and coherence. These pseudo-seismic sections were later tied to
well synthetics and lithologs. In this way, a lithology section was created for the alluvial fill. The cross-section suggested
that the eastern portion of the studied area mainly consisted of sandy fill and the western portion constituted clayey part.
This can be attributed to the depositional environment by the Indus and the Kabul Rivers. 相似文献

This study was undertaken to evaluate the biosorption potential of a natural, low-cost biosorbent, Rambai leaves (Baccaurea motleyana), to remove trace amounts of Hg(II) from aqueous solutions. It was found that the amount of Hg(II) biosorption by Rambai leaves increased with initial metal ion concentration, contact time, and solution pH but decreased as the amount of biosorbent increased. The maximum biosorption capacity was 121.95 mg/g for an initial concentration range of 5 to 120 ppb. Overall, kinetic studies showed that the Hg(II) biosorption process followed pseudo-second-order kinetics based on pseudo-first-order and intraparticle diffusion models. Isotherm data revealed that the biosorption process followed both Freundlich and Langmuir isotherms. The value of separation factor, R(L), from the Langmuir equation and rate of biosorption, n, from the Freundlich model also indicated favorable adsorption. 相似文献

This work is dedicated to the removal of free cyanide from aqueous solution by oxidation with hydrogen peroxide H2O2 catalyzed by neutral activated alumina. Effects of initial molar ratio [H2O2]0/[CN?]0, catalyst amount, pH, and temperature on cyanide removal have been examined. The presence of activated alumina has increased the reaction rate showing thus, a catalytic activity. The rate of removal of cyanides increases with rising initial molar ratio [H2O2]0/[CN?]0 but decreases at pH 10 to 12. Increasing the alumina amount from 1.0 to 30 g/L has a beneficial effect, and increasing the temperature from 20 °C to 35 °C improves cyanide removal. The kinetics of cyanide removal has been found to be of pseudo-first-order with respect to cyanide and the rate constants have been determined. 相似文献

More than half a decade has passed since the December 26th 2004 tsunami hit the Indian coast leaving a trail of ecological,
economic and human destruction in its wake. We reviewed the coastal ecological research carried out in India in the light
of the tsunami. In addition, we also briefly reviewed the ecological research in other tsunami affected countries in Asia
namely Sri Lanka, Indonesia, Thailand and Maldives in order to provide a broader perspective of ecological research after
tsunami. A basic search in ISI Web of Knowledge using keywords “tsunami” and “India” resulted in 127 peer reviewed journal
articles, of which 39 articles were pertaining to ecological sciences. In comparison, Sri Lanka, Indonesia, Thailand and Maldives
had, respectively, eight, four, 21 and two articles pertaining to ecology. In India, bioshields received the major share of
scientific interest (14 out of 39) while only one study (each) was dedicated to corals, seagrasses, seaweeds and meiofauna,
pointing to the paucity of research attention dedicated to these critical ecosystems. We noted that very few interdisciplinary
studies looked at linkages between pure/applied sciences and the social sciences in India. In addition, there appears to be
little correlation between the limited research that was done and its influence on policy in India. This review points to
gap areas in ecological research in India and highlights the lessons learnt from research in other tsunami-affected countries.
It also provides guidance on the links between science and policy that are required for effective coastal zone management. 相似文献
