Ior eor shipping1/20/2024 There is a broad range of understanding of these technologies among operators. 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. This session will discuss new and emerging EOR technologies with examples of successful application and lessons learnt. Often, however, the benefit would be greater if the technology were applied from day one. Techno-commercial aspects such as CAPEX, OPEX and particularly any perceived downside risks are often showstoppers to early implementation of new technology. Some older techniques, such as downhole vibration stimulation, are finding renewed interest. Diverting sweep by injection of microbes or solids has also been found to be beneficial. 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. In recent years, several new and emerging technologies have been studied, developed and implemented, with varying degrees of success. 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. 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. Effective real time IOR/EOR reservoir management require the ability to successfully and efficiently leverage these vast surveillance datasets collected. 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. 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.ĭepending 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. 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. In addition, the potential of polymer flooding to reduce the carbon intensity of produced oil will be discussed. This session will explore the economics (such as CAPEX, OPEX) and technical (such as injectivity, operation) aspects of this chemical EOR technology. These issues could be addressed by implementing mature, robust, and affordable EOR technologies that could result in cost and carbon-competitive oil production. The latter is related to the increasing production water cut resulting in the large volumes of water that need to be handled. It is known that costs and the energy/CO2 intensity of oil production increase with the lifetime of the oil fields. Therefore, it is our responsibility to mature inexpensive EOR technologies. However, as such, the situation is not sustainable, and companies will have to renew their investment plans to ensure that energy production meets demand. 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.
