Exploration, field surveys

According to geological exploration data and field survey of Zhujixi Coal Mine, the mine drainage water volume reaches 150 m h. Underground coohng measures are taken in this coal mine and the water temperature is above 32 C. Considering the working capacity of the current heat pump, the recoverable heat quantity could reach 4187 kW. [Pg.370]

Characteristics of slip surfaces According to the field survey and exploration revealed, the slip surfaces in the toe and the central part of the slide mainly are along the Upper and Middle Pleistocene silty clay, the slip surfaces in... [Pg.860]

It is fair to say that advances in seismic surveys over the last decade have changed the way fields are developed and managed. From being a predominantly exploration focused tool, seismic has progressed to become one of the most cost effective methods for optimising field production. In many cases, seismic has allowed operators to extend the life of mature fields by several years. [Pg.17]

Seismic surveys are traditionally an exploration and appraisal tool. However, 3-D seismic is now being used more widely as a development tool, i.e. applied for assisting in selecting well locations, and even in identifying remaining oil in a mature field. This was discussed in Section 2.0. Seismic data acquired at the appraisal stage of the field life is therefore likely to find further use during the development period. [Pg.177]

At the development planning stage, a reservoir mode/will have been constructed and used to determine the optimum method of recovering the hydrocarbons from the reservoir. The criteria for the optimum solution will most likely have been based on profitability and safety. The model Is Initially based upon a limited data set (perhaps a seismic survey, and say five exploration and appraisal wells) and will therefore be an approximation of the true description of the field. As development drilling and production commence, further data is collected and used to update both the geological model (the description of the structure, environment of deposition, diagenesis and fluid distribution) and the reservoir model (the description of the reservoir under dynamic conditions). [Pg.332]

There have been remarkably few reviews of the chemistry of decompositions and interactions of solids. The present account is specifically concerned with the kinetic characteristics described in the literature for the reactions of many and diverse compounds. Coverage necessarily includes references to a variety of relevant and closely related topics, such as the background theory of the subject, proposed mechanistic interpretations of observations, experimental methods with their shortcomings and errors, etc. In a survey of acceptable length, however, it is clearly impossible to explore in depth all features of all reports concerned with the reactivity and reactions of all solids. We believe that there is a need for separate and more detailed reviews of topics referred to here briefly. The value of individual publications in the field, which continue to appear in a not inconsiderable flow, would undoubtedly be enhanced by their discussion in the widest context. Systematic presentation and constructive comparisons of observations and reports, which are at present widely dispersed, would be expected to produce significant correlations and conclusions. Useful advances in the subject are just as likely to emerge in the form of generalizations discerned in the wealth of published material as from further individual studies of specific systems. Perhaps potential reviewers have been deterred by the combination of the formidable volume and the extensive dispersal of the information now available. [Pg.283]

The subject has been very thoroughly reviewed [1-3], but certain fundamental aspects can profitably be reconsidered in the light of some recent developments [4-6]. Certainly the most startling of these is the discovery that under conventional conditions the polymerisation of styrene by perchloric and other acids, and by the syncatalytic system stannic chloride-water, is not an ionic process. These polymerisations have been named pseudocationic . This finding is in direct contradiction to the beliefs held previously about this and related reactions. Hence a new survey of the whole field has become necessary which must start with an enumeration of those systems for which the nature of the polymerisation reaction has been established with reasonable certainty. From these boreholes one can then try to assess the nature of the intervening territory and to decide where further detailed exploration would be most profitable. [Pg.626]

This review of the chemistry and physics of microparticles and their characterization is by no means comprehensive, for the very large range of masses that can be studied with the electrodynamic balance makes it possible to explore the spectroscopy of atomic ions. This field is a large one, and Nobel laureates Hans Dehmelt and Wolfgang Paul have labored long in that fruitful scientific garden. The application of particle levitation to atmospheric aerosols, to studies of Knudsen aerosol phenomena, and to heat and mass transfer in the free-molecule regime would require as much space as this survey. [Pg.88]

Abstract in late 2008, soil and stream sediment orientation surveys were carried out to provide optimized field and analytical procedures for use in property and regional-scale exploration programs on MinCore s Tameapa property in Sinaloa Mexico. The property is host to two advanced mineral prospects named Pico Prieto (copper-molybdenum porphyry) and Venado (molybdenum-copper structurally controlled porphyry) that were first explored in detail by Las Cuevas during the 1970s and early 1980s. [Pg.407]

Tameapa property has been confined to the 12 km area surrounding the Pico Prieto and Venado prospect areas. Exploration by MinCore and previous operators has included geologic mapping, geochemical and geophysical surveys, and 43,000 m of drilling in 144 diamond drill holes. MinCore plans to systematically explore the entire property area during the 2009 and 2010 field seasons. [Pg.408]

Journal of Urban Health, vol. 79, 2002, pp. 49-59. After surveying the background of this field, the article presents possible explanations for the decline in unintentional i.e., accidental) firearms death and injuries. Possible interventions (including changes in firearms design) are also explored. [Pg.191]

As a consequence the contributions to this series do not claim to be complete or conventional reviews of the literature nor to provide regular surveys of particular fields. Instead, they seek to explore developing new frontiers in borderline areas. [Pg.162]

As indicated earlier, quantum-mechanical methods, particularly molecular orbital (MO) treatments, are tools used to explore essentially all fields of thiocarbonyl chemistry. Hence, we shall first review the current status and scope of this methodology with respect to a number of important topics. This shall be followed by a survey of the experimental and theoretical data available on the thermodynamics, structure and selected aspects of the reactivity of these compounds. [Pg.1358]

The early history of stereochemistry has been explored.174 An account of stereochemistry from the mid-19th century to 1960 surveys the proposals of van t Hoff and Le Bel as well as those of later workers in the field, such as Odd Hassel and D. H. R. Barton (1918-1998), and J. W. Comforth and V. Prelog (1906-1998).175 G. J. W. Bremer s experiments, which gave the initial experimental support to van t Hoff s stereochemical views, have been re-assessed through an analysis of the correspondence between the two chemists.176 There is a paper arguing that, in effect, van t Hoff and Le Bel produced two different theories177 and another one suggesting that John Dalton (1766-1844) was the first stereochemist.178 There is a brief analysis of the independent contributions of Alfred Werner and William Jackson Pope (1870-1939) to stereochemistry.179... [Pg.142]

The determination of the concentrations of elements in plant tissues is very important in a number of fields. These include agriculture, ecology, botanical exploration for minerals, and environmental surveys for pollutants. [Pg.242]
