The study of the Earth's sedimentary cover by seismic exploration at depth of 6-10 km, in the conditions of salt-dome tectonics, is non-trivial task. Technical capabilities for excitation and registration of seismic signal in land seismic exploration are limited because salt deposits are characterized by the powerful absorbing properties. This makes it difficult to study the sedimentary strata of rocks under many kilometers of salt domes. Therefore, in order to successfully solve the set geological tasks, it is important to correctly select optimal processing sequence of available seismic data. With help of one of domestic software processing on the example of area with salt-dome tectonics, the article discusses the main steps for building a depth-velocity model. As is known, the processing and interpretation of seismic data involve the solution of an inverse kinematic task. Since the hodographs of reflected waves cannot be accurately described by hyperbola under conditions of complex geological subsurfaces, the data are summed out of phase, which makes it difficult to determine the time. Under these conditions, the sequence of procedures, known as the standard time processing graph, which assumes the hyperbolicity of the hodographs, does not allow solving the inverse kinematic task with the required accuracy. Therefore, it was decided to use a sequence divided into two main stages. The first is preprocessing (signal processing with maximum preservation of the original wave field and the shape of the hodographs). The second is the construction of an image of the subsurfaces (depth-velocity model by the method of kinematic-dynamic transformation and migration of seismic data in the deep domain). It is shown that the use of this approach to build a processing graph made it possible to obtain a high-quality seismic image of the subsurfaces and successfully to solve the geological tasks in one of the licensed areas of Orenburgneft JSC in Saratov Region.

The estimation of reserves and resources is one of the important tasks in the activities of any oil and gas company. The purpose of an independent estimation (audit) is to accurately report on reserves and resources in accordance with a specific classification system and applicable statutory and financial regulations. Since 2013, Zarubezhneft has been keeping records of reserves of its own assets not only according to the Russian reserves and resources classification, but it also conducts annual reserves audits according to the international SPE-PRMS classification developed by the International Society of Petroleum Engineers (SPE) and the U.S. Securities and Exchange Commission (SEC). Since 2021, the Reserves and Resources Team, which includes specialists of VNIIneft STC, performs reserves audits for the Zarubezhneft Group of Companies independently, without the involvement of international auditors. In 2021, the reserves audit was carried out for 43 fields of the Zarubezhneft Group of Companies: 27 fields in Russia, 3 fields in the Republic of Uzbekistan, 2 fields in the Arab Republic of Egypt, and 11 fields in the Socialist Republic of Vietnam. In 2022, the list of estimated assets increased up to 50 fields. Due to the increasing volume of work, there appeared a need to automate the estimation processes and reduce time costs. In 2021, the work began to create software for conducting HC reserves audits according to the international SPE-PRMS classification. At the moment, the web-based application has been tested and allows one to store the results of geological assessment in the format of volumetric tables, perform engineering calculations, and generate reporting materials.

One of the most important parameters of the drilling fluid is the filtration index. Under the action of pressure drop, when drilling with overbalance, the water phase penetrates into the formation. The penetration of the aqueous phase into the oil-saturated reservoir leads to a decrease in its permeability for oil, since the aqueous phase changes the wettability and effective porosity of the rock. At the same time, not the entire volume of the aqueous phase during the reverse filtration of oil is able to release pores, especially small ones. Calculation of the volume of filtrate penetrating into the formation is an urgent task, since with this data it is possible to take a number of measures to reduce filtration, select methods for intensifying production or cleaning the bottomhole formation zone. Also, these data can be useful in calculating the reservoir productivity indicators, taking into account the contamination of the bottomhole formation zone, including the skin factor. The article presents software for calculating the volume of drilling fluid filtrate that penetrates into the reservoir during the initial opening. The author's calculation method uses analytical approaches and dependences of filtration experiments, derived using correlation and regression analysis. Laboratory data of a standard filter press test are used as input parameters: filtrate viscosity, filtration area, pressure drop, filtration process table. The necessary input parameter is the experimental dependence of the volume of the filtrate on the time of the filtration experiment, on the basis of which the parameters of instantaneous filtration are determined during the formation of the filter cake and the parameters characterizing further filtration through it. The dependence of the accumulated filtrate volume on time, determined using a filter press, is connected to the program as a separate tabular file with one of the standard extensions. The calculation for downhole conditions takes into account: filtrate viscosity at downhole temperature, repression pressure, filtration area, process time.

The paper is focused on innovative technologies of well and reservoir real-time surveillance for both data recording, and further study of the thermo-dynamic processes around the well and the reservoir. In particular, a special role is given to temperature field, the most promising method of cased-hole production logging. Today, such a tool as distributed fiber-optic downhole temperature and acoustic sensors record an enormous amount of information at a high speed, and this is possible in real time. In this regard, there is a need for the development of specialized software that allows for primary processing and interpretation of distributed temperature records by fiber-optic. This need contributed to the activation of the creation of software and methodological support (SMS) of DTS - software aimed at solving the mentioned above tasks: a portal for data documentation and analytical module for interpretation of a distributed temperature records. This paper discusses approaches to the software concept. In addition, some requirements for the composition, structure and principles of operation of such software-analytical products are substantiated and outlined, recommendations are given for their practical use when working with the results of fiber-optic temperature records. Implementation of the presented approaches to increasing the efficiency of oil and gas fields development, namely: clarification and adaptation of the current dynamic model of the field, assess the degree and reasons for the decrease in well productivity, identify the places of water breakthroughs, as well as which hydraulic fracturing ports or wellbore intervals are not flowing. A clear advantage of the proposed concept of data interpretation lies in the fact that the presented fiber-optic technologies are simultaneously elements of instrumental digital control and a digital processing system for geomonitoring processes, capable of providing optimal well control during long-term production.

Khamitov, A. T. (VNIIneft JSC) | Churanova, N. Yu. (VNIIneft JSC) | Kozhemyakina, I. A. (VNIIneft JSC) | Kalpakhchev, N. O. (VNIIneft JSC)
Oil and gas reserves and resources are fundamental assets of any oil and gas company. They affect market value of companies, determine the basis and criteria for lending for banks, as well as the business activity and strategic planning when making the most important investment decisions. Estimation of reserves and resources provides a benchmarking for comparing companies with each other and is the basis for calculating depreciation and depletion of capital. Zarubezhneft JSC, as a company is operating not only in Russian Federation, but also abroad. In 2013 it was decided to make independent reserves audit according to the international classification SPE PRMS developed by the International Society of Petroleum Engineers (SPE) and the US Securities and Exchange Commission (SEC) in order to ensure transparency of financial reporting to the State and foreign partners. Since 2018, Zarubezhneft JSC started making its own assessment of reserves. This allowed the Company developed own competence and canceled independent auditor service by the end of 2020. All the necessary work is carried out by Corporate Reserves Group, which includes specialists from the Corporate Center and VNIIneft. The reserves audit process in Zarubezhneft JSC has become an effective, understandable and demanded tool for top management to plan, analyze and monitor the state of the company's reserves and resources, providing reliable and easily interpretable estimates for making management decisions. The continual development of automation of assessment processes has made it possible to reduce the time spent by specialists for performing routine operations, minimize the human factor, increase the time for analyzing obtained results and increase the reliability of the assessment.
The paper analyzes and reviews the equipment used for dispersing and homogenizing the solid phase of drilling flushing and process fluids. It is effective to use in these processes the phenomenon of cavitation, as an intensifying factor for bringing the prepared solution to the condition, due to the destructive effects occurring in multiphase flows due to numerous microscopic water shocks - pressure surges, accompanied by the formation of shock waves and microjets of high intensity in the liquid. To implement these effects in the prepared solution, cavitation dispersers, NKD (mixers – diffuser) and NKD2 (slot) were developed. Analytical and numerical methods revealed the main regularities of the generation of cavitation in the flowing parts of the dispersants. Numerical simulation of the flow of multiphase flows by the finite element method was carried out on the Star-CCM + platform (Siemens PLM Software). The beginning of the initiation of cavitation occurs at an inlet overpressure of 0.05-0.08 MPa; at a value of 0.2-0.3 MPa, developed cavitation occurs, and the vapor-gas cavities fill the entire space of the diffuser or sheared nozzle. Full-scale samples of NKD and NKD2 were introduced into the activities of a service company that provides comprehensive services for the preparation of drilling fluids and process fluids for the construction and overhaul of wells at gas and oil fields in the Krasnodar Territory. Tests have shown that cavitation dispersants increase the speed of preparation and conditioning of clay suspensions by several times in comparison with standard mixing systems with stirrers. Time spent on mud preparation reduced to 12 h. The article also presents other results of experimental industrial tests of equipment. The obtained economic effects are confirmed by the acts of implementation.
