... of clay, mud and silt. The important feature to note is that this definition does not describe the mineralogy but rather the grain size. In this definition, clay refers to clay sized particles, i.e. < 1/256 mm. Whilst clay can refer to grain size it can also refer to clay minerals, and it is the dual...

... permeability of the load-bearing rock frame can be calculated based on the Kozeny-Carman equation. The non-load-bearing matrix is assumed to be composed of fine material that is smaller than the pores in the load-bearing rock frame, for example, very fine sand, silt and clay. This fine material alters...

... to specific lithologies, e.g. sands, silts and clays. The bound fluid content, free fluid content, and permeability are obtained for each component. A combination of NMR and conventional logs is then used to determine the typical porosity of each lithology, which in turn is used to estimate the cross...

... ABSTRACT We have developed a model for predicting compressional and shear slowness in sand-silt-clay sequences from a limited suite of wireline logs. It may be applied in areas where the neutron-density crossplot exhibits the familiar boomerang pattern. It differs from current practices...

... inside the pore system. Integration of Nuclear Magnetic, Epithermal Neutron and Electromagnetic tool responses allows the design of a model where clay, silt and sand are the matrix volumetric unknowns. Also clay bound water, capillary bound water, free water and gas volumes are computed. The resulting...

... for the determination of these parameters which is more consistent with core and production data. Grain size analysis of the reservoirs shows that the clay content is generally low although the silt content may be significant. Core data and log responses indicate that the porosity distribution and solids conductivity...

... ABSTRACT When a sand contains a large amount of silt and clay it is often difficult to detect zones that contain gas using only the Archie Saturation Relationship. However, gas may be detected in these shaly formations using certain quick-look techniques. Log examples of these are presented...
