Abstract

Summary

The work presents examples of the results obtained by the authors on the detection of gas traps at the Olhivske and Makiivske gas condensate fields. A 3-D seismic survey was carried out within these two fields. Angular seismic images were used to calculate the distributions of the values of seismic indicators of hydrocarbons. Their construction was performed by direct transformation of seismograms of common sources into seismic images of the geological medium. Seismic indicators of hydrocarbons, which are expedient to use for searching for gas traps in the fields of the northern side of the Dnipro-Donetsk Depression have been determined. The distributions of signs of seismic hydrocarbon indicators anomalies in accordance with their relationship to the top, bottom of the gas reservoir or to the gas reservoir itself, demonstrated on real seismic exploration data. The research results were taken into account in the recommendations for wells drilling. The presence of commercial gas reserves, which are confined to the detected amplitude anomalies, is confirmed by the results of drilling and well testing.
