The differencebetween the demand and production curves should be compensated byfluids from new non-conventional reservoirs, mainly Shale Gas.In many of the recently discovered fields, theproduced fluids could be classified as near-critical, with some casespresenting retrograde condensation of around 30%. Material balancesand numerical simulations, which are used for predicting the fluidsproduction behavior and proposing development strategies, require anadequate characterization of the reservoir fluids and a good fittingof the laboratory data, in order to adequately reproduce fields andwells behaviors.This work presents data and also results andconclusions based on the thermodynamic modelling of these fluids,with focus on saturation points and retrograde behavior. Both thePeng-Robinson and RKPR EoS?s were used, together with differentways of characterizing the heavy fractions. Volume shifts wereapplied in order to better predict the volumetric behavior.
