About this Workshop
SESSION 1. Physical and chemical methods
Physical and chemical oil recovery methods help to improve oil recovery efficiency for all types of fields, including high water-cut brownfields. These methods help to reduce water-oil surface tension (with surfactant), optimize water-oil mobility ratio and improve reservoir coverage (with polymers). Primary technologies for the method include polymer flooding, surfactant polymer flooding and ASP (anionic surfactants – soda – polymer).
In early 2000s thermal and gas methods exceeded physical and chemical methods in a number of completed projects. However, the number of pilot and full-scale projects (using physical and chemical methods) increased significantly since 2010, as well as expanding of its’ application as a result of technological achievements and rise in the efficiency. Polymer and surfactant polymer flooding technologies are the most popular in China, Canada and India. It’s also in use in Oman, Argentina, Great Britain, some countries use it offshore. The number of such projects in Russia and Kazakhstan is increasing, 2017 was a benchmark as two companies announced the successful completion of polymer flooding and ASP pilots in Russia.
A pilot programme is critical for future successful projects with physical and chemical oil recovery methods. It allows tselection of select optimum surfactant, polymer and alkali for the exact formation. Throughout the project monitoring and efficiency evaluation step forward. After the fall in oil price, operating companies have started to pay special attention to cutting capital and operating costs and try to keep major effects for formation.
In fractured carbonates and high-temperature reservoirs, these technologies are still applied as pilots only. Research centers and oil and gas companies are looking for new decisions, new polymers and surfactants for such conditions.
We suggest discussing the following topics:
- Latest achievements and projects: lessons learned
- Water treatment for physical and chemical methods: pros and cons
- Physicochemical methods for heavy oil
- Solutions for fractured reservoir
SESSION 2. Gas methods
Gas, associated gas or air injection to maintain reservoir pressure and enhance oil recovery spread long before full-scale water injection. Major part of completed gas and water-alternated-gas projects were done in US using miscible displacement. Technology and economic limits prevent the wider use (such as risks of gas breakthrough, areal sweeping efficiency decrease and infrastructure high cost). At the same time requirement strengthening for associated gas use may induce search of gas injection implementation ways. Modern technologies allow to minimize risks at early stages of gas and WAG methods design, which application, which leads a rising tide of interest to the technology in different parts of the world, including Russia.
This session will cover the following:
- Technologies pros and cons (gas, water-alternated-gas, different agents, in - situ combustion)
- How to set the stage for a large-scale project to minimize risks and maximize effects (lab investigation, nuances of modeling, requirements to pilot testing)
- Injection monitoring and control
- Case studies and implementation plans for projects in Russia
- Gas methods for unconventional reservoirs (fractured low-permeable carbonates, source rocks, extra low permeable reservoirs)
SESSION 3. Thermal methods
Thermal methods are considered to be the most prepared technologically and technically out of all the EOR methods. These methods can be used in the most difficult physical and geological conditions and allow to produce oil with a viscosity of tens and hundreds of thousands mPas. Moreover, final oil recovery increases from 6-20% up to 30-50%, the numbers can be achieved by thermal methods only.
Modern theory of thermal oil reservoir stimulation by heat carrier injection or fire flooding are based on multiphase multicomponent filtration theory, which also considers phase transition and chemical in-situ reactions (mainly oxidative). The main advantage of thermal methods vs other EOR technologies is simultaneous hydrodynamic and thermodynamic effects. Heat influences all the components of reservoir (solid, liquid, gaseous) and changes the context and filtration conditions radically. As a result, oil viscosity decreases which increases oil mobility, structural-mechanical properties weaken, boundary layers reduce in thickness, capillary imbibition improves, oil fractions gasify, wettability of displacing agent improve, and hence displacement efficiency and ultimate recovery increase
So far, thermal methods have no alternative for high-viscous and super-viscous oil field development. Bringing the oil recovery up to 50% and above aligns with doubling of these fields economic reserves.
Thermal methods appear to be one of the most important technologies to develop heavy oil fields, both as the only method and combined with other technologies. This trend will persist in the future.
Themes for presentations and discussions:
- Case studies and projects implementation plans in Russia
- Thermal front monitoring and injection control
- Thermal methods: recent trends in development
- Thermal methods for unconventional reservoirs (shallow oil-saturated thickness, gas cap super-viscous oil deposit, fractured low-permeable heavy oil carbonates, source rocks)
SESSION 4. Innovative methods
This session completes the full picture of enhanced oil recovery methods. We invite you to speak and discuss biological methods and all the newest technologies which were not considered in the first three sessions. The programme committee may transform this session into roundtable format.
Attendance will be limited to a maximum of 100 delegates with proven experience and/or knowledge of the subject areas being covered.
Detailed information on Workshop Programme will be posted on SPE Russian and Caspian regional website.
- Presentation materials will not be published, therefore formal papers and handouts are not expected from speakers. PowerPoint presentations will be posted on a specific SPE URL address after the Workshop and be available for Workshop attendees only.
- The Committee will prepare a full report containing the highlights of the Workshop description. This report will be circulated to all attendees. The copyright of the summary report will belong to SPE.
In keeping with Workshop objectives and the SPE mission, excessive commercialism in posters or presentations will not be permitted. Company logo must be limited to the poster slide and used only to indicate the affiliation of the presenter and others involved in the work.
