520			_aThe integration of sedimentological, petrophysical and geochemical data is presented in a new conceptual geological model for the Neuquén Group in the Llancanelo field, Malargüe Department, northern Neuquén basin in south Mendoza. The multi-disciplinary approach and the integration of work scales converge in a three-dimensional model of the reservoir that incorporates facies described in outcrop, their correlatives in the subsoil and diverse geochemical patterns. The studies of core data indicate the calcareous cement and clay content as the main quality controls of the reservoir. In addition, the study of FRX (X-ray fluorescence) on cores and cuttings reveals a correlation between the content of elements such as vanadium with the presence of biodegradable oils, molybdenum with higher mobility hydrocarbons, and strontium as a geochemical marker of sandy levels with shaly-siltstone matrix with sealant behavior between the main reservoirs; this is represented in a three-dimensional model of the field from Gaussian Sequential Simulation, obtaining a spatial distribution of chemical elements. Through sonic and resistive well logs, an electro-facies model was made sensitive to variations in clay, cementation and saturation of hydrocarbons. A total of five electro-facies are discriminated that show a close relationship with the litho-facies defined in cores and with patterns of chemical elements obtained from FRX; they are used to condition the calculations of petrophysical properties of each of the reservoirs. In outcrops, cycles of conglomerate facies are observed that begin with burdensome sediments, interpreted as deposit debris flows with a silt-clay matrix of tabular geometry, which upwards interspersed with similar lithologies of flows in mantle with sandy matrix; the latter are dominant towards the top of the cycles and exhibit tabular and/or gritty lenticular geometries. Cycle caps generally have different degrees of cementation associated with paleosols and subaerial exposure; such successions are interpreted as stacks of alluvial fans that intersected in internal positions of the basin and gradation towards fluvial systems. The acquisition of FRX and multispectral gamma rays in outcrop allows to link these levels with their correlatives in the subsoil.
