Core Competencies of Oil&Gas Exploration Company
By M. VlasovSummaryThe Oil&Gas industry today is commoditized and de-consolidated in terms of the value chain. Most of the field works are executed not by the Oil&Gas companies themselves, but by their contractors, which means that technological development is concentrated in the arms of these contractors. The situation in Oil&Gas exploration sector is the most challenging, as there are almost no “easy” resources left to discover. This puts the pressure on the exploration sector to effectively find the resources commercially feasible for further production. As a result, Oil&Gas Exploration Companies shall concentrate their efforts around their internal capabilities

Fast Exploration. Acceleration of Exploration Phase Due to a More Aggressive and More Risky Exploration Program
Authors D. Khakimov, F. Bikbaev and R. UkurovSummaryExploration phase in an average acreage in Russia usually takes 5–7 years, and usually includes creating detailed exploration program approved by government regulators, 2D or 3D seismic surveys, exploration drilling. The duration of exploration work is associated with the need to perform work consistently, with the gradual removal of geological uncertainties with minimal risks and investments. This approach provides more flexibility to change the exploration program in case of new information at any step, which helps to avoid design errors and drilling of “dry” wells. On the other hand, “slowness” in exploration greatly reduce project economy and even can lead to a negative NPV and EMV. Accelerating the exploration program for one-year increase EMV value to 10%, and give additional value from 200 million rubles to 2 billion rubles depending on the project. This effect achieved by involving into production one year earlier resulting earlier positive cash flow. To assess the economic effect, the authors selected a typical license block located in the Khanty-Mansiysk Autonomous District. Economical calculation showed that exploration phase period could be reduced from 6 to 3 years without losing any geological information and EMV increasing 1.5 times.

Future of Exploration: Personnel, Technologies, Business Processes
Authors V. Shashel, A. Sizykh and V. ZhukovSummaryExploration is at the forefront of any vertically integrated oil company. By means of geological exploration, the portfolio of production projects is replenished, preserving and enhancing the continuity of the “conveyor” of field development. In the modern world, geological exploration faces new challenges - the search for complex structures, further exploration of the marginal zones of already discovered deposits, the study of deep-lying and unconventional objects. We must effectively address all these challenges in the face of great volatility in oil prices, a growing demand for qualified personnel, and limited by market sanctions. The report will discuss the role of Functions in solving the challenges and challenges posed by the Business Environment.

Sampling of the Downhole Samples of Reservoir Oil at Non-Transfusing Oil Inflow into the Well
Authors E. Tikhomirov and A. LukashovSummaryThe aim of bottomhole sampling is to obtain a small volume of fluid, which is identical to the reservoir oil at initial reservoir conditions. The results of study of reservoir oil PVT (abbreviation from Pressure, Volume, Temperature) properties made in the laboratory can then reasonably be applied to identify phase behavior and properties of reservoir fluids under reservoir conditions. Knowledge of PVT properties of reservoir oil is necessary to estimate of oil capacity, designing of reservoir development and its economic viability. PVT properties of reservoir oil are estimated from: - the study of subsurface oil samples; - the study of recombined samples from the test separator; - mathematical simulation using equation-of-state and empirical correlations. Representative samples of the reservoir oil can be collected mainly by subsurface sampling. In cases of extremely tight (low permeable) reservoirs it may be virtually impossible to get sufficient flow rate to lift the liquids without excessive pressure draw-down and corresponding degassing of reservoir oil at bottomhole conditions. This article deals with on technical and technological solution of subsurface oil sampling when an oil not flow to surface. The use of such a method will help to solve the problem of reliable identification of the reservoir oil properties at reservoir conditions.

Overcoming Imaging Challenges in Today’s Market
Authors L. Nasipov and D. NikolenkoSummarySeismic data have a key role to play in exploration and field development, enabling reservoir delineation and characterization as well as reducing drilling risks. We discuss recent seismic technology developments and show how they have provided new insights into subsurface geology, reservoir properties, and drilling hazards. One of the most significant advances in recent years has been in earth model building and imaging and has been driven by a combination of new algorithms such as full-waveform inversion (FWI) and sophisticated imaging techniques, and an increase in experience and wide-spread usage of those technologies, which can significantly improve interpretation for both newly acquired data and heritage conventional data. We show examples of seismic data processed with the latest technology, including earth model building with FWI compensation of variable illumination with least-squares migration. These advanced technologies allow us to overcome very complex imaging and geological challenges and enable achieving a wide range of subsurface imaging objectives across the E&P life cycle.

Integrated Asset Assessment - as a Tool for Rapid Decision Making under Uncertainties
Authors M. Dymochkina, P. Kiselev, N. Vershigora and A. AnashkinSummaryAny investment decision - from well testing to the purchase of a new asset - are a large number of calculations with different decision logic. The larger the volume of the proposed investment, the more important to use an integrated approach in the decision to the assessment of the uncertainties and risks of the project. The Gazprom Neft Science and Technology Center has a methodological group that oversees the comprehensive assessment and analysis of investment projects. The tasks of this group is in addition to the development of methodological approaches, but also dissemination them within the Company to increase the general level of culture with uncertainties. The practice of recent years has shown that the most effective way to distribute best practices and techniques to a wide range of users is to introduce it into convenient digital solutions, which also has functions of training and developing the competencies of employees.

An Overview of Deep-Water Play Types in the Eastern Black Sea
More LessSummaryThe Black Sea is divided into two separate basins, the Western and Eastern Black Sea Basins (WBSB and EBSB), divided by the Mid-Black Sea High (Andrusov Ridge and Arkhangelsky High, Fig. 1 ). Whereas about 20 deepwater exploration wells were drilled in the WBSB, the EBSB saw only 3 wells to date (Tari and Simmons, 2018). The first one of these, the HPX-1 well were drilled by BP in the Turkish sector of the EBSB, very close to the Georgian maritime border in 2005. This well spud in 1,529 m water depth and it was the first truly deepwater well in the entire Black Sea.

Artificial Intelligence in Exploration. Examples from Wintershall Dea
By T. HelbigSummaryBeing at the beginning of E&P value chain, exploration is a prime target for numerous digital applications. Unlike in operations or development, exploration work is usually focusing on unstructured data (reports, studies etc.), especially at the early stage. At this stage, ideation and interpretation are prevalent whereas in the other two domains modeling and engineering play a much larger role. Here, systems acting as digital advisors or cognitive search engines can be employed to reduce the time needed to come to conclusions. At later stages, big data applications and machine learning can be used to enhance the interpretation of seismic or petrophysical data. All of these technologies are commonly referenced as “Artificial Intelligence”.

Implementation of Geological and Technological Uncertainties to the Process of Development Planning of a Hydrocarbon Fields Group
Authors V. Legkokonets, A. Korobkin and D. SafinSummaryThe main goal of development planning of a new hydrocarbon region is to achieve the most robust development plan while taking into account uncertainties of each individual hydrocarbon field. The simplest solution for uncertainty quantification of several fields is conducting multitude of reservoir simulations, however this method is heavily limited by available computation resources. This work describes an algorithm which allows to calculate the least uncertain development plan within set production and economic constraints. Algorithm is based on genetic optimization method accounts for field infrastructure, production profile, cash flow limits while minimizing uncertainty. Proposed plan uncertainty is reduced through change of field exploitation start date and intensity of field development. Algorithm should be used as a decision support tool in the process of finding an optimal solution in hydrocarbon fields developing strategies.
