The main restriction for neutron methods, which researchers faced with in process of exploring opening’s estimation of oil deposits’ productive strata, is low mineralization of bedded waters. It is considered that the most effective way to solve this problem is using high porosity reservoirs and mineralization of bedded water up to 50–100 g/l. The experience of long-term geophysical control under development of oil and gas deposit of Anastasievsko-Troitskoe field’s IV productive horizon proved that in case of usage of special methods of conducting well researches, this formulated problem is successfully solved with lower mineralization (up to 15–30 g/l) of bedded waters in conditions of inhomogeneous geological section and multi-phased filtration of bedded fluids. In the following work are shown physical premises of neutron methods in detection of non-worked out productive strata, quality requirements of geophysical materials, technology of well explorations. An example of non-worked out strata’s detection in one of field’s oil well by using GIS complex is also given in this work.
