Project Final Report-DE-NT0004651-In this project, new fluids have been designed to efficiently drill deepwater wells that can be cost-effectively drilled. The new fluids are heavy-liquid foams with low density at shallow depths and high density at drilling depths. Designing new fluids to efficiently drill deepwater wells that can not be costeffectively drilled with current technologies. The new fluids will be heavy liquid foams that have low-density at shallow dept to avoid formation breakdown and high density at drilling depth to control formation pressure. The goal of this project is to provide industry with formulations of new fluids for reducing casing programs and thus well construction cost in deepwater development. Studying the effects of flue gas/CO2 huff n’ puff on incremental oil recovery in Louisiana oilfields bearing light oil. Arriving at a quantitative understanding for the three-dimensional controlled-source electromagnetic (CSEM) geophysical response of typical Gulf of Mexico hydrocarbon reservoirs.
