    Analiza zastosowań sondy neutronowej rejestrującej neutrony termiczne i nadtermiczne (NNTE) do wyznaczania nasycenia węglowodorami w warunkach wysokich zasoleń wód złożowych na wybranych przykładach z niżu polskiego

    The M.Sc. thesis contains information related to the analysis of the NNTE well-bore probe used for registering thermal and epithermal neutrons in detection of hydrocarbonsbearing formations of the high salinity fluids. In the thesis geological environment, conditions of well-bore measurements and methods of nuclear measurements together with physical phenomena used with these methods were described. In particular, idea of NNTE probe was presented, which provide with useful bulk parameters: thermal neutron capture cross section, neutron porosity and natural radioactivity. One of the most important thing described in the thesis relate to the problem of different interpretation results being caused by the different calibration monograms used.

    UGS wells in depleted fields
    (2011) Szabó, Dávid; Pinka, Ján; Fedorko, Ľuboš
    The Underground Gas Storage (UGS) facilities are mainly built in hydrocarbon reservoirs (depleted oil and gas fields), in aquifers and also in salt caverns using proven techniques based on the best use of geology and geophysics. From the international perspective, Slovakia plays an important role in the European gas industry. Transporting one-fifth of the natural gas consumed in western European countries, it is one of the largest natural gas transit countries. Before the end of its path across Slovakia, the transported natural gas reaches the Lab UGS facility in the Slovakia. This paper describes oil and gas depleted reservoirs and techniques that apply in the UGS field.
