Monitoring and surveillance&nbsp;(M&amp;S) is one of the key requisites for assessing the effectiveness&nbsp;and success&nbsp;of&nbsp;an IOR&nbsp;project. These projects can include waterflooding, gas flooding, chemical injection, or any other type of EOR. It will help&nbsp;understand, track, monitor and predict the&nbsp;injectant&nbsp;plume migration, flow paths, and breakthrough times.&nbsp;The M&amp;S helps in&nbsp;quantifying&nbsp;the performance of the IOR project objectives. It provides a&nbsp;good understanding of the remaining oil saturation (ROS) and its&nbsp;distribution in the reservoir during and after the flood.A comprehensive&nbsp;and advanced&nbsp;monitoring and surveillance (M&amp;S) program&nbsp;has to be&nbsp;developed&nbsp;for any given IOR project.&nbsp;The best practices of any such M&amp;S program should include conventional, advanced&nbsp;and emerging novel technologies for wellbore and inter-well measurements. These include&nbsp;advanced&nbsp;time-lapse pulsed neutron, resistivity, diffusion logs, and bore-hole gravity measurements, cross-well geophysical measurements,&nbsp;water and gas&nbsp;tracers, geochemical,&nbsp;compositional and&nbsp;soil gas analyses, and 4D seismic and surface gravity measurements.&nbsp;The&nbsp;data obtained from the M&amp;S program provide&nbsp;a better understanding of the reservoir dynamics&nbsp;and can be used&nbsp;to refine the reservoir simulation model&nbsp;and fine tune its parameters. This&nbsp;presentation&nbsp;reviews&nbsp;some proven best practices and draw examples from on-going projects and related&nbsp;novel technologies being deployed.&nbsp;We&nbsp;will then look at the new horizon for M&amp;S technologies for EOR.

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
