... Abstract Deepwater fields, such as those encountered in the Gulf of Mexico (GoM), often exhibit reservoir tar deposits and asphaltene instability ( Dumont et al, 2012 , Mullins et al, 2016 ). This instability may manifest itself within the reservoir in the form of out of equilibrium asphaltene...
