As the demand for petroleum and other strategic minerals intensifies, there has been a corresponding need for more accurate / realistic micro-geophysical models that govern acoustic, electromagnetic, and nuclear measurements made in petroleum reservoirs and commercial mineral deposits.

The main goal of these efforts is to improve measurement accuracy of the petroleum/mineral content of these natural structures.

Exploration of Earth, its moon, and Mars for petroleum and strategic mineral deposits is accomplished in part through the use of nuclear technology in the form of remote sensing devices that utilize high energy neutrons and gamma rays.  These very penetrating nuclear particles and rays are injected into porous media where they propagate and subsequently acquire spatial, temporal, and energy features that can be measured and then used by experts to determine some of the physical properties of these porous media.

For example, total fluid content (porosity) and fluid fractional volumes (oil/gas/water saturations) of earth's formations are routinely determined by oilfield service companies such as Schlumberger and Halliburton with their nuclear probes called sondes or logging tools. In favorable cases, specific elements may be determined, such as carbon, calcium, iron, oxygen, sulfur, silicon; nickel and manganese; or aluminum, as in bauxite or certain clay minerals.

Nuclear micro-geophysical models govern the propagation of neutrons and gamma rays in such porous media. These models have generally assumed infinitesimal pore sizes with no laminations. However, many commercially successful petroleum reservoirs contain vuggy porous systems with finite pore sizes and laminated beds with alternating fluid and mineral content.

This website describes major advances in nuclear micro-geophysical modeling in thinly laminated media and vuggy porous media, both with finite pore sizes. The impact of pore size on fast neutron, thermal neutron, and gamma ray measurements (including bulk density) is provided.

Recently, Doctor Neutron successfully added FRACTAL DIMENSION to his model: pores are now permitted to have radii distributed from a maximum value (Rmax) down to aminimum value (Rmin), with a self-similar pore size distribution governed by a single fractal dimension (D).

Also included are Doctor Neutron's patents on the use of neutron activation analyses to determine the frac height and frac location of fractures induced in earth formations.
