摘要： A method of using nuclear spectroscopy measurements acquired while drilling a subsurface formation including: measuring indicators of a plurality of absolute or relative formation elemental concentrations; processing the measurements to determine a petrophysical parameter associated with the subsurface formation while drilling, and using the petrophysical parameter to determine a drilling parameter. The petrophysical parameter may include, for instance, the permeability of the subsurface formation and the drilling parameter may include, for instance, a change in the orientation of a directional drilling assembly or the point at which to stop drilling. The invention further involves an apparatus adapted to carry out the inventive method.

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.

摘要： There is provided a method of accurately estimating the permeability of sedimentary rock formations from well logging data. The method involves a short relaxation time strategy with the identification of the key k-Lambda parameter S/V.sub.p, which is the surface-to-pore ratio. The inverse of T.sub.2 is related to this ratio by the surface relaxivity, .rho.2. The k-Lambda estimator is given by: ##EQU1## where: .DELTA.V.sub.1 represents the volume elements of the T.sub.2 distribution and the sum over i=1 to n represents some set of early to later volume elements; and V.sub.p is the total pore volume.

摘要： Methods are disclosed which provide for determining in situ the characteristics of hydrocarbons including oil API gravity in a formation traversed by a borehole. The vanadium content in the formation is determined from a logging tool.
