Развитие методики 3D-сейсморазведки в арктическом регионе

Abstract

This article discusses the technological aspects of developing a methodology for detailed seismic surveying using the 3D method in the Russian Arctic. The primary aim is to enhance the economic efficiency of the exploration stage in oil and gas field development. The paper highlights the significance and substantiates the advantages of 3D seismic surveys that make it possible to drill production wells without the need for exploratory drilling. It is established that the principal impediment to technological advancements in seismic surveying within Arctic regions is the restrictive policies of Western nations, which primarily take the form of sanctions. Factors influencing the economic efficiency of seismic surveying include the quality of fieldwork management and workers' professional skills, both of which can catalyze the evolution of seismic survey techniques. The article presents an illustrative case of detailed seismic surveys conducted on the Gyda Peninsula. An innovative seismic survey technique is introduced, and an integrated indicator, which is grounded in criteria reflecting the quality of work, is proposed and employed for an objective assessment of economic efficiency. The proposed methodology has been successfully tested, proving its advantages, and the results obtained are of value for the sector of seismic surveying. It is proposed that the methodology should be used by geophysical companies deploying high-density seismic survey methods to find new hydrocarbon fields in northern territories.
