Abstract

Summary

The abstract is concerned with increasing the informativity of the well logging while investigating the shaliness of terrigenous oil-and-gas reservoirs and near-surface rocks based on a combination of gamma-ray logging, density gamma-gamma logging and neutron-neutron logging (GR + DL + NL). Number of new methods is developed for determining the parameters of shaliness, namely, the content of clay minerals, their density and hydrogen index. Method for estimating the type of clay mineral according to the GR + DL + NL data is proposed. The method is an available alternative to lithological core studies and to more expensive and difficult logging methods.
