The key to success in IOR/EOR implementation is project management. In this panel session, we will discuss development strategies for EOR application including project planning, execution, evaluation, and expansion. We will reveal how best practices have evolved and have been altered in different companies to ensure the success of EOR application. IOR can also be a key enabler for successful EOR application. Integrating IOR in overall EOR application will yield better economic results. This could be influenced by lessons learnt, industry trends, or technological advancements. Project integration and collaboration between different parties and disciplines including talent development will also be discussed in the panel.
Due to lower energy demand caused by the pandemic and CO2 emissions control challenges prevailing on the global agenda over the past few years, oil and gas companies have significantly reduced investments into new projects, especially the cost-intensive EOR projects. However, as such, the situation is not sustainable, and companies will have to renew their investment plans to ensure that energy production meets demand. Therefore, it is our responsibility to mature inexpensive EOR technologies.
It is known that costs and the energy/CO2 intensity of oil production increase with the lifetime of the oil fields. The latter is related to the increasing production water cut resulting in the large volumes of water that need to be handled. These issues could be addressed by implementing mature, robust, and affordable EOR technologies that could result in cost and carbon-competitive oil production. One such technology is polymer flooding.
This session will explore the economics (such as CAPEX, OPEX) and technical (such as injectivity, operation) aspects of this chemical EOR technology. In addition, the potential of polymer flooding to reduce the carbon intensity of produced oil will be discussed.

The successful operation of an IOR/EOR scheme in oil and gas fields requires timely reaction to dynamic and sometimes rapidly changing injection and production behaviours in the field. The traditional approach to decision making relying on only subsurface models to understand flood performance is giving way to the ‘Big Data’ approach which leverages tools like Data Analytics, Artificial Intelligence (AI), Machine Learning and Internet of Things (IoT) for successful IOR/EOR management.
Depending on the IOR/EOR approach, a myriad of data types ranging from the surface (multiphase injection/production) to subsurface (flood performance diagnostics, advanced observation wells, well log and 4D seismic) need to be collected, processed and analysed in an efficient manner. As a result, the sheer volume of information to be processed could be prohibitively cumbersome and slow, especially if traditional workflows continue to be employed. Effective real time IOR/EOR reservoir management require the ability to successfully and efficiently leverage these vast surveillance datasets collected. Hence, integration of smart IOR/EOR field operations and digital technologies are increasingly becoming key factors in achieving the ultimate goal of maximising value from oil and gas fields.
This session will explore how different organisations have been able to integrate digital workflows and a combination of IOR/EOR methods to overcome challenges encountered in all phases of IOR/EOR projects life cycle, from pilot to full field development and ultimately managing the fields.

In recent years, several new and emerging technologies have been studied, developed and implemented, with varying degrees of success. Changing rock and fluids properties, namely reservoir wettability, interfacial tension, and phase viscosities are some of the popular opportunities for further enhancing recovery in waterflooded oil fields using nano-particles, low salinity water, alkalis (A), surfactants (S) and polymers (P) in ASP or SP combinations. Diverting sweep by injection of microbes or solids has also been found to be beneficial. Some older techniques, such as downhole vibration stimulation, are finding renewed interest. Techno-commercial aspects such as CAPEX, OPEX and particularly any perceived downside risks are often showstoppers to early implementation of new technology. Often, however, the benefit would be greater if the technology were applied from day one.
This session will discuss new and emerging EOR technologies with examples of successful application and lessons learnt.

It is widely acknowledged that for mature basins, successful application of IOR/EOR has the potential to increase recovery, extend field life, as well as help stimulate field redevelopments. There is a broad range of understanding of these technologies among operators. Throughout those numerous projects, there might have been lessons learnt and opportunities for improvement discovered, and these information can help the industry move quickly up the learning curve and anticipate possible challenges and mitigations required.
This session will include case studies from pilots, project designs and implementation; focusing on lessons learnt, root causes of their challenges, realisation of these pilots compared to what was planned, and ways forward. Participants are therefore encouraged to share their valuable experiences and insights regarding IOR/EOR projects, discuss success stories, as well as examine unintended outcomes and recommendations. These insights will be valuable to industry professionals involved in similar projects.

As the global economy seek solutions for decarbonisation, Carbon Capture, Utilisation and Sequestration (CCUS) will play a vital role to meet this goal. One of the largest industrial use of CO2 is in EOR, whereby CO2 is injected to maximise oil recovery. Within the upstream sphere, CO2 used for EOR is a proven recovery mechanism and such deployment will not only help to maximise oil but will also reduce carbon emissions. Additionally, decarbonisation initiatives within the existing IOR/EOR projects are being explored to meet the urgent global energy transition.
This session will highlight and discuss the different aspects of CCU opportunities and challenges in CO2 EOR project implementation and decarbonisation efforts to reduce carbon footprint, both from the technical and non-technical standpoints.
CCU and CO2 EOR deployment and decarbonisation means business opportunities, value drivers and enablers, EOR technology innovation and creativity, and development in subsurface and surface studies, existing projects and new frontiers.
