  2. Formation evaluation - Wikipedia

    en.wikipedia.org/wiki/Formation_evaluation

    The formation evaluation problem is a matter of answering two questions: What are the lower limits for porosity, permeability and upper limits for water saturation that permit profitable production from a particular formation or pay zone; in a particular geographic area; in a particular economic climate.

  3. Mathematics Subject Classification - Wikipedia

    en.wikipedia.org/wiki/Mathematics_Subject...

    The Mathematics Subject Classification (MSC) is an alphanumerical classification scheme that has collaboratively been produced by staff of, and based on the coverage of, the two major mathematical reviewing databases, Mathematical Reviews and Zentralblatt MATH. The MSC is used by many mathematics journals, which ask authors of research papers ...

  4. Formation (group theory) - Wikipedia

    en.wikipedia.org/wiki/Formation_(group_theory)

    In group theory, a branch of mathematics, a formation is a class of groups closed under taking images and such that if G/M and G/N are in the formation then so is G/M∩N. Gaschütz (1962) introduced formations to unify the theory of Hall subgroups and Carter subgroups of finite solvable groups .

    [1] Mathematics is essential in the natural sciences, engineering, medicine, finance, computer science, and the social sciences. Although mathematics is extensively used for modeling phenomena, the fundamental truths of mathematics are independent of any scientific experimentation.

    Analysis is the branch of mathematics dealing with continuous functions, limits, and related theories, such as differentiation, integration, measure, infinite sequences, series, and analytic functions. [1] [2] These theories are usually studied in the context of real and complex numbers and functions.

    The SPWLA definition of Formation Evaluation is: "The analysis and interpretation of well-log data, drill-stem tests, etc. in terms of the nature of the formations and their fluid content. The objectives of formation evaluation are to ascertain if commercially producible hydrocarbons (or other forms of energy and minerals) are present,

  8. Class formation - Wikipedia

    1 → A F → U → E/F → 1. corresponding to the fundamental class u E/F in H 2 (E/F, A F). The Weil group of the whole formation is defined to be the inverse limit of the Weil groups of all the layers G/F, for F an open subgroup of G. The reciprocity map of the class formation (G, A) induces an isomorphism from A G to the abelianization of ...
