dc.description.resumen | The sandstones of the Lajas Formation represent the main tight-gas reservoir of the Neuquén Basin. Diagenesis plays a fundamental role in this type of reservoir because diagenetic minerals have a high impact on porosity and permeability. This study presents the diagenetic characterization of the Lajas sandstones located in the productive area of Sierra Barrosa, central part of the Huincul High in the Neuquén Basin. The objective is to evaluate diagenetic processes and their impact on reservoir quality. The facies analyzed belong to deltaic and uvial depositional systems with a variety of sub-settings including delta front (proximal and distal mouth bar), prodelta, delta plain (distributary channels and interdistributary bays), uvial channel inll and uvial plain deposits. The analyzed samples consist of very coarse-grained to ne-grained, medium- to poorly-sorted and texturally immature feldspathic litharenites and lithic feldarenites (sensu Folk et al. 1970) along with siltstones and subordinate ne-grained clast- and matrix-supported polimictic conglomerates. Detrital minerals include lithic fragments, mono- and polycrystalline quartz, and feldspar with K-feldspar>plagioclase. Lithic fragments are volcanic and volcanoclastic detritus and subordinate plutonic, sedimentary and metamorphic grains. The amount of cement varies considerably and includes pyrite, clays, quartz, feldspar, carbonates, barite and subordinated Zn-Pb suldes. Porosity depends on facies and their amount of cements. | es_ES |
