Lightweight Nodes Bring New Opportunities
Authors J. Quigley and L. NasipovSummaryThe quality and usefulness of images and reservoir attributes obtained from land seismic surveys can be improved by increasing the density of traces acquired per square kilometre. Seismic survey designs must however reflect the practical reality and limitations of available equipment, operational logistics and cost, which leads to compromises in the designs used and the results obtained. On the receiver side, to significantly increase the acquired receiver count and trace density, the logistical barriers associated with existing receiver equipment must be eliminated. Experience acquiring many high-density surveys using cabled-telemetry recording equipment highlighted both the geophysical potential of point-source/point-receiver techniques, and the challenges of extending this technology beyond 250,00 channels using cabled-telemetry equipment. The introduction of new very small, light, and simple nodal receiver equipment enables such a paradigm shift in operational logistics. As operational barriers are eliminated the deployment of very large receiver spreads becomes practical, and the path opens towards more effective and flexible survey designs, delivering higher trace densities and improved seismic images.

Business Approach to the Oil and Gas Exploration
Authors M. Aksenov and V. VorobyevSummaryThe purpose of this work is to describe the approach «Gazprom Neft» to managing the geological exploration business and preparing reserves for production. In this presentation, Gazprom Neft’s experience in working with exploration projects will be shown on real examples: the sequence of actions, how to implement the project faster, how to reduce the costs on exploration, how to justify the development of oilfield. The implemented approach is focused on exploration business management and the implementation of an optimal strategy for reservoir study. The project logic of the works is formed on the basis of the best practices of oil and gas majors, service companies, our personal experience and changes geological exploration not only in the Russian Federation, but also in the World.

Application of Modern Techniques for Integrated Well and Seismic Data Interpretation to Clarify Geology of Kovyktinskoje Field
Authors A. Smirnov, I. Jakovlev, O. Kuretova, R. Tugushev, F. Kevorkov, A. Rybnikov and F. ZeleznyakSummaryMain goal of the project are detailed investigation of sedimentary deposits (including upper and halogen – carbonate sections) and creation of unified seismogeological model of Kovitkinskiy license area based on 5050 square kilometers of 3D seismic. To achieve the goals in deep seismic processing was performed including wide azimuth migration ES360 which allowed to get both reflection and diffraction components of the wave field. Processing was followed by detailed interpretation, detailed inversion and pore pressure analyses. Based on seismic study detailed geological and geomechanical models where generated to assist exploration drilling.

Problems of Geological Exploration of Old Oil-and-Gas Regions
Authors A. Ziyatdinov, R. Khisamov, A. Bachkov and V. BazarevskayaSummaryThe Republic of Tatarstan certainly belongs to one of the oldest oil regions of our country. Geological exploration of the old oil and gas regions is complicated by a number of objective factors, including: the deterioration of the resource base, the lack of highly promising prospecting objects and an increase in the share of hard-to-recover reserves. However, in the Republic of Tatarstan a great experience has been accumulated in maintaining a sufficiently high level of geological exploration success even in conditions of high exploration of mineral resources. First of all, attention is paid to unconventional objects (Perm bitumens, Domanic deposits, crystalline basement) and innovative methods of prospecting and exploration of hydrocarbon deposits. PJSC TATNEFT annually prepares projects for seismic exploration, where areas with a large number of identified and mapped structures and a low density of seismic profile networks are selected as priority research areas. For successful exploration work, adaptation of the strategy and tactics of their conduct is necessary, taking into account the characteristics of the old oil and gas regions. For example, Western companies have long been using VOI and probabilistic-statistical evaluation of search assets to make decisions on further work on search assets. In PJSC Tatneft, as part of the risk management concept, these methods are also successfully applied.
