... requires the presence of two separate phases (i.e., liquid, oil phase and gas phase). That is, the gas washing here starts only around 30,000 years after the gas cap starts forming. Before the formation of a gas cap, added methane only leads to increasing GOR accompanied by the increasing concentration...

... of FMWD together with a previously computed correlation between the raw optical densities at different frequencies and asphaltene content was used to provide Real Time quantification of asphaltene concentration to optimize the trajectory and placement of the producer wells. The subject of this work deals...

... in identifying deposits containing high concentrations of potassium-rich minerals. The ability to distinguish between the gamma emissions of uranium, thorium and potassium means that the gamma ray spectral profile can be used to identify various clay minerals. The use of this profile to identify minerals...

... the petrophysical composition. We assign random porosity, shale concentration, and water saturation to each layer using a Gaussian distribution for each of these variables. The only exceptions are the bottom five layers where we have an aquifer, and its transition to mostly oil (C16H34), which is the only fluid...
