...Paper contributions and structure Our motivating case study above suggested a complex interplay between injector placement, hydrocarbon production, and the amount of CO 2 gas emitted from the waterflooding operation. This indicates non-trivial correlations between emission costs and well...

... the fields and how to allocate the remaining gas in the efficient injectors for enhanced condensate recovery. The results triggered a change in injection strategy to rank gas disposition internally in optimized locations both in Smørbukk and Smørbukk Sør fields, and to split the injection between the two...

... model. EnOpt has previously been used to optimise well control settings for a fixed number of producers and injectors. It relies on the ensemble of well control settings from which the sensitivities of a suitably constructed objective function are approximated. The sensitivities to the control settings...

... Abstract Inter-well tracer test (IWTT) is a method used to track the movement of injection fluid and identify the field connectivity. The mechanism of IWTTs consists of injecting slugs of tracer in the water injector and observing the tracer at the producers from water samples. One...

Improved tools and methods, such as residence time distribution (RTD) analysis, can quantify how effective water and gas...
