Session 2. Monitoring, Control, Case Studies

«EOR is an endless pilot project». But implementation of EOR is changing this common perception. We will consider best practices in all EOR methods.

From the first field experiment to full-field implementation, the most important task for each engineer is correct assessment of EOR effect. Monitoring and performance control options, challenges during implementation and rollout, production well stock problems, injectivity losses, extra costs in oil processing and facilities corrosion – all that and more you can discuss during this session.

We will stress on:

  • Model or analytics? This is the question
  • How can we survive without waterflooding trends?
  • Instrumental control methods: why and how much?
  • 1 MMT from EOR: myth or reality?
  • How dropping of extra costs for oil processing can kill successful EOR project?
  • What are the opportunities of EOR projects efficient monitoring for efficiency increase?

Session 3. Hybrid Methods and New Technologies

Hybrid EOR methods are developing these days. The hybrid methods based on formation stimulation synergy of few EOR technologies combination or few agents at the same time. In general terms hybrid EOR methods can be divided into two big groups. The first one is joint implementation of different types of “classic” EOR methods – chemical, thermal or gas. The second involves combined use of different agents and technologies within one “classic” EOR type. And one of the key factors for high efficiency of hybrid EOR is composite application of newest working agents.

During the session we are going to discuss:

  • Chemical EOR methods with combination of different chemical agents: caustic-surfactant-polymer; caustic-solvent-polymer; surfactant-polymer-foam and others
  • Chemical EOR with nanoparticles
  • Combination of heat transfer fluid with chemical agents
  • Combination of thermal EOR with gas agents, including CO2
  • Thermal EOR methods with nanoparticles, including: gas injection, SAGD, electromagnetic heating etc.
  • New areas in gas methods and water alternating-gas-with chemical agents
  • Hydrocarbon gases and CO2 miscible displacement with nanoparticles
  • Technological optimization for hybrid methods
  • Perspectives for hybrid methods development

Session 4. EOR Future Development: New Reality

Hydrocarbon production went through facings, from lowered consumption due to quarantines, concerns about alternate fuels development to higher and higher KPIs.

This is capital intensive area with postponed result, which compels us to find routes to unlock the potential of the technology and assess risks very optimistically.

Let’s find the way not just to save but develop EOR in new normal.

We suggest the following topics:

  • EOR for multizone reservoir – one technology for many layers
  • Economics – risk assessment and limits to rational optimism
  • Alternate sources – geothermal energy to increase oil recovery
  • CO2 injection for EOR in the scope of carbon management (CCS/CCUS)
  • New chemical agents – alkoholes, esters
  • EOR impact on major construction – reuse of chemical agents
  • EOR for high temperature and abnormally low formation pressure
  • Fractured reservoirs – involvement of matrix to work

Round Table: Stimulation of EOR Application

EOR application requires not just proper engineering evaluation, but significant investments. Its recoupment scares away license holders from some EOR methods. From the other hand, EOR implementation stimulation is a priority in traditional oil production regions. For these regions prolongation of mature fields use is also a social issue, as production companies are often an economic mainstay.

At the same time, launch of production from noncommercial fields with high density or hard-to-recover reserves is a growth driver for both regions with declining production of conventional hydrocarbons and new petroleum production clusters. This makes crucial to open a dialog with license holders and government bodies at all levels.

At the round table, we will try to find common ground for leading industry experts and government representatives and discuss prospective of EOR implementation stimulation on Russian fields.
