Hydrocarbon exploration and reservoir analysis

The article provides a critical analysis of existing methods for forecasting hydrocarbon accumulations. It is noted that the main disadvantages of the existing methods are that it is a priori assumed that a very high signal-to-noise ratio was obtained, as well as a high resolution of seismic data, while in reality this is not the case. The proposed forecasting technique differs in that here the well log data (WGD) are used in an intermediate stage of processing to improve the signal-to-noise ratio of seismic data and their resolution. The forecasting technique is described, in the development of which the author also participated. The developed technique was tested in the Hovsan area of the Absheron oil and gas region of Azerbaijan, its brief geological and geophysical characteristics were reflected in the article. In the main part, the results of the application of this method are presented, with a recommendation of the location of the new planned well and the wells currently in operation. The reliability of the results is closely related to the seismic-geological conditions of the study area, as well as the depth and level of seismic data processing and the degree of similarity of the two seismic traces taken near the reference and projected wells, as well as the accuracy of the log interpretation data.
