The Pan European Reserves and Resources Reporting Committee (PERC) Standard for Reporting of Exploration Results, Mineral Resources and Mineral Reserves (further referred to as the 'PERC Reporting Standard') sets out the minimum standards, additional guidelines and recommendations for the Public Reporting of Exploration Results (including Exploration Targets), Mineral Resources and Mineral Reserves.
Results of theoretical analysis and experimental investigations for transport in porous media are presented. A new approach to modelling of transport in porous media is developed and a number of new percolation models is considered. The models allow to obtain analytical correlations for relative phase permeabilities for different porous media. Different methods of intensification of economic minerals based on new physical effects of reconstruction of the rock's pore space structure, are analysed.
The monograph is of interest for reservoir and chemical engineers, for specialists in reservoir characterization and simulation, for core analysts and researchers, and for post-graduate students in the above-mentioned areas.
В неглубоких водоемах пермского периода привольно себя чувствовали дискозавриски - интересные существа, сочетавшие в своем строении признаки амфибий и рептилий. По современной систематике (Иванов, Черепанов, 2004) дискозавриски относятся к отряду антракозавров, подклассу батрахозавров («лягушкоящеров»), классу амфибий. Охотились дискозавриски, по всей видимости, на мелких личинок насекомых, различных водных беспозвоночных и рыбок. Ископаемые остатки представителей семейства дискозаврисцид найдены и в Приуралье, в Оренбургской области и в Куединском районе Пермского края, в местонахождении Куединекие Ключики. <...>

Humans need salt to live. A person eating a diet rich in red meat typically gets all the salt he needs from food, but a person eating only vegetables and grains does not. When people began settling into agricultural communities, they needed salt for themselves and their livestock. Furthermore, vast quantities of salt were needed to preserve food, especially fish.
The purpose of this course is to introduce you to Petrel Geophysics functionality and the workflows. You will go thorough different functionalities in Petrel and learn how to efficiently use these for interpreting 2D/3D seismic data. The powerful tools and algorithms can be used to calculate size/area of your leads and prospects which, in turn, can be used for reserves estimation. You will be provided with a ready-to-use Petrel 2013 project containing 2D/3D seismic and well data. The exercises provide hands on training that enables you to explore the functionalities through dedicated exercises. <...>
Carbonate reservoirs hold 60% of the world’s hydrocarbon reserves. In order to obtain a reliable estimate of reserves in a given reservoir and also to prepare a development plan for optimum production of hydrocarbons from the reservoir, a quantitative assessment of the petrophysical parameters of the reservoir is essential. However, petrophysical properties of carbonates are not easy to predict because of the post-depositional processes like dissolution, re-crystallization and re-precipitation, which alter the properties of the carbonate reservoirs and make them extremely heterogeneous and, hence, bear a profound effect on the productivity and flow dynamics in the reservoir. However, we lack an adequate understanding of how to dynamically model these post-depositional processes. The evolution of porosity through dissolution channels, solution vugs, fractures, etc., is all post-depositional processes. For realistic modelling of the reservoir, we need to understand the dynamics of the fluid flow through the complex network of the carbonate matrix. This calls for proper integration of various geophysical, geological, petrophysical, core data and dynamic data such as MDT, PLT, well test analysis. <...>
Such evolution of language is natural and well-established. For instance, “Geochronology” was originally coined during the waning stages of the great Age-of-the-Earth debate as a means of distinguishing timescales relevant to Earth processes from timescales relevant to humans (Williams 1893). Eighty-eight years later, Berger and York (1981) coined the term “Thermochronology,” which has evolved as a branch of geochronology aimed at constraining thermal histories of rocks, where (typically) the thermally activated diffusive loss of a radiogenic daughter governs the ages we measure.
Granite petrology has achieved significant progress since Tuttle and Bowen (1958) wrote the monograph on the Origin of granite in the light of experimental studies in the system NaAISi308-KAISi308-SiOrH20. Since then, the components CaAI2Si20 s, FeO, MgO, and excess alumina have been added to the pure system Ab-Or-Qz-H20 in order to include plagioclase and common mafic minerals in the investigations.
