Geoskin is the negative skin resulting from the limited extent of pseudo-fracture channels (PFCs) around the wellbore. Modelling studies have been conducted to determine the relationship between thickness, radius, number and location of PFCs, permeability contrast with the matrix and the quantity of negative geoskin. The model showed that the two wells in the braided fluvial reservoir lie at the extremes of a continuum in which the scale of channels is the only varying parameter. The study also showed that the interpretation of the skin can be used as a measure of the near well bore properties prevailing in such reservoirs due to high permeability and small scale channels.
