    The pioneering paintings of Gus Archie moved log interpretation into log research with the advent of the equation that bears his identify. next advancements have combined empiricism, physics, mathematical algorithms, and geological or engineering versions as equipment utilized to petrophysical measurements in boreholes around the globe. Principles of Mathematical Petrophysics reports the applying of arithmetic to petrophysics in a structure that crystallizes the topic as a subdiscipline applicable for the workstations of this present day. the subject material is of large curiosity to either educational and commercial execs who paintings with subsurface info utilized to power, hydrology, and environmental issues.
    This e-book is the 1st of its variety, in that it addresses mathematical petrophysics as a different self-discipline. different books in petrophysics are both large descriptions of device layout or interpretation options, regularly in an ad hoc remedy. It covers mathematical equipment which are utilized to borehole and middle petrophysical measurements to estimate rock homes of fluid saturation, pore kinds, permeability, mineralogy, facies, and reservoir characterization. those tools are verified via quite a few case reviews and summaries of functions. Principles of Mathematical Petrophysics is a useful source for each person operating with information on the topic of petrophysics.

    By Fernando Schnaid

    Demanding a radical wisdom of fabric behaviour and numerical modelling, website characterisation and in situ try interpretation are not any longer simply uncomplicated empirical recommendations.

    Giving a severe appraisal of the knowledge and evaluation of the stress-strain-time and power features of geomaterials, this booklet explores new interpretation tools for measuring houses of various soil formations.

    Emphasis is given to the 5 most typically encountered in situ try recommendations:

    • standard penetration assessments
    • cone penetration assessments
    • vane try
    • pressuremeter assessments
    • dilatometer tests

    Ideal for practicing engineers within the fields of geomechanics and environmental engineering, this e-book solves quite a few universal difficulties in website characterisation. it's also a worthwhile spouse for college kids coming to the tip in their engineering classes and searching to paintings during this sector.

  • Download E-books Seismic Waves and Rays in Elastic Media: 34 (Handbook of Geophysical Exploration: Seismic Exploration) PDF

    By M.A. Slawinski

    This booklet seeks to discover seismic phenomena in elastic media and emphasizes the interdependence of mathematical formula and actual that means. the aim of this identify - that's meant for senior undergraduate and graduate scholars in addition to scientists attracted to quantitative seismology - is to exploit points of continuum mechanics, wave idea and ray idea to explain phenomena due to the propagation of waves.

    The ebook is split into 3 components: Elastic continua, Waves and rays, and Variational formula of rays. partially I, continuum mechanics are used to explain the fabric in which seismic waves propagate, and to formulate a method of equations to check the behaviour of such fabric. partly II, those equations are used to spot the kinds of physique waves propagating in elastic continua in addition to to specific their velocities and displacements by way of the homes of those continua. to resolve the equations of movement in anisotropic inhomogeneous continua, the high-frequency approximation is used and establishes the idea that of a ray. partly III, it truly is proven that during elastic continua a ray is tantamount to a trajectory alongside which a seismic sign propagates in line with the variational precept of desk bound go back and forth time.

    By Pierre M. Adler

    This publication offers a scientific remedy of the geometrical and shipping houses of fractures, fracture networks, and fractured porous media.

    It is split into significant components. the 1st half bargains with geometry of person fractures and of fracture networks. using the dimensionless density rationalizes the implications for the percolation threshold of the networks. It provides the the most important benefit of grouping the numerical info for varied fracture shapes.

    The moment half bargains regularly with permeability below regular stipulations of fractures, fracture networks, and fractured porous media. back the implications for numerous forms of networks could be rationalized through the dimensionless density. A bankruptcy is devoted to 2 section stream in fractured porous media.
