I feel honored to write this citation for Life Membership for Shiv Dasgupta. I first met Shiv about 18 years ago in Bahrain when he was pushing advanced modeling techniques by incorporating multidisciplinary measurements. His work bridged disciplines; the results have proven effective in accurate delineation of subsurface. He always is where new technologies are hitting the applications.

Shiv received his undergraduate geophysics education at the Indian School of Mines, and pursued graduate work in St. Louis University and Washington University, St Louis, followed by an MBA degree from Illinois University. He began his industry career with Conoco where he made an early impact by working on multicomponent seismology effort for lithology prediction. This was followed by tenure at Amoco where he worked on exploration projects to acquire, process, and interpret multicomponent seismic data. He served as a champion of shear-wave exploration at Amoco. After spending eight years with Conoco, Amoco, and Mitchell Energy he joined Saudi Aramco where he stayed for over 28 years. Throughout his career Shiv has contributed with many pioneering and noteworthy innovations in geophysics.

At Aramco he worked on various aspects of seismic exploration and interpretation and built subsurface models that culminated in the discovery of a major new exploration and development system in the Arabian Gulf. In the Ghawar Field of Saudi Arabia, his innovative workflows produced interpretation models that generated phenomenal drilling success. Subsequently, he developed computerized integrated workflows that combined seismic interpretation with geosteering application. He authored a patent on a seismic while drilling application. During his entire career, he pioneered many successful technologies. He led the microseismic monitoring project for Arab-D reservoir water-flood monitoring and in setting up a technology test site facility in the Ghawar Field. Every time something new needed to be pushed past established minds, Shiv was willing to help. In addition to this Shiv has spent a significant part of his career mentoring and educating his colleagues through courses and lecture. Even today he is working on a book on geophysics for non-geophysicists.

All of these lead automatically to a high level of professional society work in which he increasingly bridged the gap between petroleum engineering and geophysics. Shiv organized many workshops inside and outside of his company in support of this effort. It is not unusual to get a call from Shiv late at night wanting to discuss the application of geophysics to reservoir problems. Shiv has been actively involved with the Society of Exploration Geophysicists for many years; he has served on several SEG committees with great passion and enthusiasm. His outlook has always been global. As an active member of the Global Affairs Committee and Regional Coordinator he has been instrumental in developing SEG into a truly international organization. It gives me great deal of pleasure and satisfaction that SEG bestows this well-deserved honor upon him in recognition for his accomplishments.

Today, Shiv, his wife Rumki call Houston their new home. His stays engaged in geophysics by consulting and helping many of his colleagues.

Emerging geophysical tools for reservoir monitoring in intelligent fields

Summaryː Intelligent instrumented fields or i-fields hold promise to be the next game changer technology in the Exploration & Production industry. The instrumented oilfield consists of a network of sensors permanently installed in wells and on the surface or on the seabed. The network will continuously monitor a range of parameters, including temperature, pressure, acoustics and fluid flow. Changes in reservoir dynamic properties that occur during production and injection are recorded by the sensors in real time. Real time monitoring of flood fronts between wells provide "an early warning system" to optimize field development strategies and longer term recovery.

Geophysical monitoring tools are based on measurements of physical properties and their contrasts over the producing life of a reservoir. Each tool responds to contrasts in a physical property like electrical resistivity, magnetic susceptibility, density and elastic modulii. In intelligent oilfields, a variety of seismic and non-seismic instruments will be permanently installed along with other instruments in the total infrastructure. The measurements will image reservoir fluid distribution during the life of a field. Some tools are proven while many others are emerging. Time lapse seismic measurements or 4D seismic is a mature technology used successfully in many fields to monitor injected fluid flood fronts, locate by-passed oil and map pressure compartmentalization. Permanently installed multicomponent seismic receiver arrays on sea floor and in boreholes are being used for acquiring 4D seismic frequent intervals. The additional shear wave data monitor in-situ stress changes, fracturing and pressure fronts. The permanent receivers can also be used for continuously recording passive seismic data. In passive mode the sensors will detect triggered microseismic events emanated from minute slippages in reservoir rocks due to injection and production activities. Recorded events could map the flood front movement and preferential flow paths at interwell scale. Electromagnetic or EM methods, on the other hand, rely on changes in electrical properties due to reservoir saturation changes as hydrocarbons are produced and water injected. Surface deformation caused due to pore pressure changes in reservoirs with production and injection activities can be continuously monitored using satellite radar interferometry (InSAR), ground-based GPS, and surface tilt meters.

This lecture will discuss the various proven and emerging geophysical tools that demonstrate promise in detecting and mapping of reservoir flood front movement during the life cycle of a producing field. Geophysical methods could be incorporated in the suite of instrumentation deployed in the intelligent fields of the future. Permanently installed geophysical instruments in the i-fields could bring a new paradigm in real time field wide reservoir fluid monitoring.
