    摘要: A method for determining total clay content of an earth formation based on elemental concentration logs obtained from a logging tool. This method avoids the need for obtaining an aluminum concentration measurement. First, the concentrations of a plurality of elements in the formation are determined without measuring an aluminum concentration. Then, at least the silicon, calcium, and iron concentrations are combined in accordance with a function determined by regression analysis to produce an estimate of the total clay content.

    摘要: Methods are disclosed which provide for quantifying and characterizing the mineral content of a formation as a function of depth. Elemental data derived from logging tools are input into an element-mineral transform operation, preferably a matrix which is constructed using multivariate statistical analysis on previously available data, to determine the quantity of at least one or more dominant minerals in the formation. From the mineral quantity information and the elemental log data, the formation minerals are further characterized. Information regarding the character and quantities of formation minerals is further used to obtain improved determinations of formation characteristics such as the cation exchange capacity and water saturation, and the grain density and formation porosity, as well as to obtain an increased understanding of the formation such as the depositional environment of the formation. A determination of formation characteristics and an increased understanding of the formation are both vital to production decisions concerning the formation.

    摘要: A modification to the Coates-Timur relationship to produce a more coherent relationship applicable to carbonate formations is disclosed. In this method, permeability may be determined using porosity and the ratio of bound fluid volume to (1—bound fluid volume). This method also allows for improved estimation of irreducible water saturation of a carbonate formation using the ratio of kc and (eφf+kc). Likewise, the bound fluid volume of a carbonate formation may be determined using the ratio of φkc and (eφf+kc). In these relationships, e, x, and f are constants according to the following relationships e=xc, f=bc+1, x is between 1 and 100 mD (preferably 10 mD).

    摘要: Methods for determining the permeability of an earth formation traversed by a borehole are provided and comprise: logging the borehole to determine indications of at least a plurality of elements in the formation; determining the mineralogical content of the formation from the elemental indications; determining the porosity of the formation; and determining the permeability of the formation as a function of the determined mineralogical content and porosity. The mineralogical content of the formation is preferably determined according to a transform which relates elemental concentrations of the formation to mineral weight percentages. The permeability is preferably determined according to a transform which equates the permeability to a product of the function of the formation porosity, the maximum feldspar content in a given zone of the formation, and an exponential function of the summation of pedetermined mineral components of the formation and residual weighted by a redetermined constant for each mineral component and the residual. If desired, the element to mineral transform can be combined with the formation mineral and porosity to permeability transform, thereby eliminating the step of determining the mineralogical content via the element-mineral transform.
