Dear President Gurbanguly Berdimuhamedov pays great attention to the tasks of developing the oil and gas industry, strengthening its production, scientific and technical potential, on the basis of which large-scale investments are made in this industry. These activities are aimed at increasing the competitiveness of the country's fuel and energy complex in the world and ensuring its contribution to socio-economic development.
In this regard, President Gurbanguly Berdimuhamedov stressed the need to introduce new digital technologies in the oil and gas sector.
The innovative development of the oil and gas industry will become one of the main activities of industry research institutions, taking into account the “Digital Fields” and Smart Wells projects.
“Digital Fields” is a set of software and hardware that allows you to manage the oil reservoir and hydrocarbon production, as well as to continuously optimize the development of fields.
The main tasks that this technology solves:
a) an increase in the speed and volume of oil and gas production by monitoring the operation of the field without damaging it online;
b) reducing the cost of operating the field, that is, increasing the profitability of the development of hydrocarbon reserves;
c) extension of the life cycle of a hydrocarbon reservoir.
A feature of “Digital Fields” is the ability to flexibly adapt to specific conditions. Unlike other automation systems, “Digital Fields” adjusts actions in real time for maximum production. In addition to the supply of a large amount of data that is analyzed for planning and decision-making, the technology allows assessing both short-term and long-term prospects of an oil and gas asset, simulating events and situations, thereby experimenting with a computer program based on information received from the facility and avoiding errors in reality.
“Digital Fields” consists of the following main components: integrated automation, technical means of data collection and analysis, solutions for increasing the productivity of oil and gas companies. There is such a component as the integration of field models. It allows, by combining reservoir and infrastructure models that will be located on the territory of the field, to determine the best development option for the facility where oil and gas production is planned, or to improve production by reducing costs and minimizing errors.
Also one of the main components of the “Digital Field” is the Smart Well technology. With the help of telemetry, it allows you to remotely regulate the technological mode of the well operation. “Digital Fields” can operate both in one well and in the entire field.
The “Digital Fields” includes ERP-management systems that allow linking production with other processes occurring in production, distribution systems for energy consumption and water supply at the production site, an uninterruptible power supply system (for unstable power supply of the site), as well as the use of other IT-achievements of modern science.
As for the positive sides that this technology has: optimization of the consumption of electricity, steam, water and other energy resources; reducing risks in the field of industrial safety and accidents; the technology works and adapts to any conditions and types of deposits; increasing the rate and volumes of hydrocarbon production and reducing the costs of this process; the ability to calculate the best option for the development and operation of oil and gas fields for maximum production and minimum costs; provides the longest life cycle for oil and gas reservoirs.
These are the main positives that can be seen in this technology. An example is the achievements of the “Digital Fields” project at the West Salym field by “Salym Petroleum Development” for the period from 2008 to 2016.
Focusing on Western practice, today many specialists use the term “Smart Wells. Its peculiarity lies in the ability to automatically adjust the operating parameters to changing environmental conditions. Automation of processes in the oil industry today is one of the most promising areas of development, since it allows you to increase efficiency and reduce the cost of work, which is becoming increasingly important in the context of global competition.
The principle of operation of an intelligent well is based on collecting information from a sensor system and subsequent two-stage analysis: initially, the system rejects clearly erroneous information, produces initial diagnostic conclusions, and then transfers all information for more detailed analysis to a powerful software package, where, under the supervision of qualified personnel, the received data and a decision is made to change or save the set parameters. Such an assessment can be carried out both automatically and with the participation of a specialist.
The term “Smart Wells” is a relatively new concept in the oil and gas industry. In its broadest sense, an intelligent well is a facility equipped with sensor and / or control valve systems that allow monitoring of operating parameters. Thanks to the introduction of such systems, it is possible to increase the economic efficiency of production, ensure the safety of operations, and also have a positive effect on the recovery factor.
As an example of the operation of an intelligent well, one can cite a situation when natural gas produced at one of the horizons is injected directly into the oil-bearing horizon to maintain the required in-situ pressure, bypassing the need for preliminary gas supply to the wellhead. Thus, the implementation of some of the operations is possible using only downhole equipment. At the same time, in the part of operations to correct the parameters of work, the participation of a specialist is not required at all.
The next stage in the development of such IT technologies should naturally be the emergence of intelligent fields, in which an automated system will control not only downhole equipment, but also all components of the field infrastructure: pipelines, intelligent wells themselves and other elements.
