This paper provides a brief overview of geology and petroleum geology of the Dniepr-Donets Basin (DDB) and the Ukrainian Carpathians. Selected examples reveal the significant undiscovered hydrocarbon potential of these provinces and show that it is due to the presence of a large number of promising but poorly explored hydrocarbon accumulations and traps. It is also shown that revision of the existing geological models of many known fields will significantly increase reserve estimates for these fields. This will permit an increase in the annual hydrocarbon production at each of the underexplored fields in a short period of time. The authors also show that the revision of geological models is needed for many structural traps. They failed to detect hydrocarbons, owing to ‘dry’ wells or wells that were not even tested, despite logging data, indicating the presence of hydrocarbon-bearing reservoirs. This will make it possible to bring into operation previously missed productive formations. Special attention is paid to predicting new hydrocarbon fields in underexplored areas of the Ukrainian Carpathians. Very important further research in the DDB should involve the revision of geological models of both productive and unproductive structural traps, associated with salt tectonics at depths penetrated by wells. As well, it should include exploration for new structural traps near salt stems and beneath the overhangs of salt diapirs, where they may be much more numerous than currently thought and larger in size. The implementation of the exploration and geological research discussed in this paper will ensure that Ukraine’s hydrocarbon resources will meet domestic demand for oil and gas and also become an important source of petroleum for Europe.

W referacie wskazano zagrożenia związane z globalnym ociepleniem klimatu i opisano światową kampanię na rzecz powstrzymania wzrostu stężenia gazów cieplarnianych w atmosferze. Wyspecyfikowano kategorie emisji gazów cieplarnianych przypisywane górnictwu naftowemu. Scharakteryzowano aktualne zasady krajowych inwentaryzacji lotnych emisji gazów cieplarnianych z górnictwa nafty i gazu podane przez IPCC oraz omówiono wskazówki dotyczące inwentaryzacji, opracowane dla przedsiębiorstw branży przez jej organizacje naukowe i ekologiczne.

In the paper the threats connected to global warming and the world campaign to stop the rise of greenhouse gas concentration in the atmosphere have been described. Categories of greenhouse gas emission assigned to oil and gas exploration and production activities have been specified. Present principles of national fugitive emission inventory elaborated by IPCC for oil and gas E&P sector are presented together with inventory guidelines prepared for individual industrial companies by scientific and ecological organizations.

The SSE 'Yuzhmorgeoshelf has developed and successfully applies a complex of geophysical methods in practice of oil and gas exploration in shallow water and transition zones. The complex of methods includes 2D seismic survey, multi-wave seismic exploration, high resolution electric prospecting, gravity-magnetic prospecting and space sounding. The efficiency of the methods applied is shown on the examples of the Pri-Azov estuary areas and North-West Caspian shallow water. As a preceding method an electric prospecting in modifications of secondary seismoelectric effect and induced polarization is used.

The paper comments on the toxicity of drilling materials, drilling muds and drilling wastes and describes briefly the different ways of toxicity assessment. Polish method based on the results of chemical analysis is presented more widely and "toxicity value" concept is explained together with the method of calculation. Some information on drilling waste toxicity forecasting is also given.

W pracy opisano podstawy metody procesów przejściowych (metoda elektromagnetyczna w domenie czasu - TDEM), w tym metodykę prac polowych, przetwarzania danych i prac interpretacyjnych. Przedstawiono także zagadnienia zasięgu głębokościowego i rozdzielczości metody procesów przejściowych. Obliczono i przeanalizowano krzywe sondowań dla modeli odpowiadających trójwarstwowym przekrojom geoelektrycznym z wysokooporową warstwą środkową i niskooporową warstwą górną i dolną. Przeanalizowano obliczone krzywe sondowań pod względem możliwości kartowania struktur wysokooporowych, które mogą być związane z występowaniem złóż węglowodorów. Przedstawiono możliwości zastosowania metody sondowań TDEM w wykrywaniu złóż węglowodorów.

This paper describes the principles of the transient electromagnetic method (time- domain electromagnetic method, TDEM) as well as TDEM measurement systems, data processing and 1D data interpretation techniques. The paper discusses also some problems of resolution and penetration depth of the method. We calculated and discussed TDEM sounding curves for three-layer geoelectric models, which consisted of a high-resistivity middle layer and low-resistivity upper and lower layers. The calculated curves were analysed from a viewpoint of a possible mapping of high-resistivity structures that could be hydrocarbon-prospective areas. The application of TDEM sounding to oil and gas exploration was evaluated.
