Developing and introducing new technology is crucial to the continued success of every business. That is why innovation is part of the fabric of Gazprom Neft. The Company’s technology specialists primarily focus on the following areas:
By 2025, more than 50% of the Company’s oil will be produced using new technology. Based on 2014 results the percentage of wells drilled using advanced technology was 40%. This ratio is a record for the Russian oil and gas sector.
In 2014, Gazprom Neft established its code for ongoing technological progress in exploration and production.
Gazprom Neft specialists have identified 10 key areas for technological development, which will have an impact on all areas of the oil production process, from geological exploration to development management. An understanding of the company’s future prospects and their development potential is crucial for future growth.
The first horizontal well has been drilled using hydraulic fracturing to explore the Palyanovskaya zone at the Krasnoleninskoye field. This is Gazprom Neft’s first operation of this type in areas with non-traditional reserves of hydrocarbons, including the Bazhenov formation.
The “Bazhenov formation” is a geological layer located in the centre of Western Siberia, running to depths of
Gazprom Neft’s second project — the development of shale oil reserves at the Bazhenov-Abalak formation of the South Priobskoye field is ongoing. In March 2014, Gazprom Neft was granted a license for geological development of Gazpromneft-Khantos. Over the last six months experts have been analysing geophysical data, specialist research has been conducted of the drill core and a second 3D seismic survey data has been conducted. The first stage of the programme, entailing the drilling of 4 inclined exploration wells in
Well drilling has been completed as part of a pilot project for chemical flooding based on a three-component ASP mix (soda, surfactants and polymer) at the Salym group of fields and equipment has been delivered for injecting the mix into the reservoir.
ASP is a promising method for enhancing oil recovery based on chemical flooding of the reservoir with a three-component mix (anionic surface active substances (surfactants), soda and polymer). The oil recovery factor can be increased by injecting a composition of certain chemicals into the well. Anionic surfactants and soda promote a reduction of interfacial tension between water and oil and the polymer improves the process of oil displacement using the injected water.
The increase in the oil recovery factor at depleted and high water cut fields may be as much as
The pilot injection of the three-component ASP mix at the Salym group of fields is scheduled to begin in the second half of 2015. Once the injection process is complete, an analysis will be carried out on the effectiveness of the technology and the feasibility of industrial-level implementation will be assessed. The soda-surfactant-polymer flooding technology will be widely used in West Siberian fields, where potential growth in the oil recovery factor is 8 to 25%.
For the first time in Russia an oil well has been drilled at the Yamal Peninsula with a horizontal borehole that is 1,500 m long, with a total length of about 4,200 m. 91% of the horizontal section is located in the oil-saturated reservoir at the Novoportovskoye field, which has a high rock permeability, helping to ensure high yields without having to use hydraulic fracturing.
For the first time in Russia, seismic surveys have been conducted using innovative wireless seismic technology. Compared with traditional seismic survey technologies, this technology requires half the land area, reducing necessary forest clearance by half. The results of the pilot project have demonstrated that when implemented over an area of 400 km2 the new survey method preserves approximately 200 hectares of forest, or some 60 thousand trees.
Electrical prospecting field work has been completed on 600 km2 at the Tympuchikan and Vakunay licence areas. This has become the world’s largest project in electrical prospecting using a near-field zone transient electromagnetic sounding method (TEM) based on the number of physical TEM points (over 7,600), the number of transmitting loops, the volume of data obtained and the time required for project performance.
Work has begun on introducing the GeoMate information system, which was developed by Gazprom Neft. A feature of the system is that it uses innovative approaches to analyse geological and production data. The platform’s built-in mathematical unit covers more than 200 geological parameters of the development. The GeoMate system collates approximately 80 percent of all data available, including the analysis of geological and geophysical information — seismic data, maps, the results of well surveys, well-core data. Access to a single, fully comprehensive IT environment provides Gazprom Neft employees with direct and immediate access to all data, making it possible to construct field models and identify and map promising zones and formations. Detailed and thorough analysis supports geologists, geophysicists, petro-physicists and other specialists in developing integrated solutions for field prospecting and development, drawing on a wide range of data. Developing a proprietary software solution has also ended a reliance on imported products.
Innovation at Gazprom Neft is led by Regional Competence Centres (RCC) working to develop technical solutions for the Company’s key challenges. So far the Company has established four RCCs: Gazpromneft-Khantos (low permeability reservoir development); Gazpromneft-Vostok (fractured reservoir development); Gazpromneft-Muravlenko (pipeline operation); Gazpromneft-Noyabrskneftegaz (recovery of remaining reserves from depleted fields).
Gazpromneft NTC has formed a special working group and an institute of technical experts to provide organizational and technical support to all the RCCs.
The Company has a strong portfolio of innovative projects, including:
Rotary steerable systems (RSSs) are a new generation of downhole drilling equipment which improve the drilling quality for directional wells. The RSS’s continuously rotating drill string produces a less tortuous wellbore and therefore a clearer horizontal well path.
Full-scale introduction of RSSs will improve the following operations:
The company is innovative when developing and managing business processes. One of the key projects is the integrated Electronic Asset Development programme (the ERA project). The management and control system enables automation of the company’s key business processes, unification and systematisation of data sources, preparation of high-quality analytical reports and achievement of maximum oil production levels.
