| Resumen | Stratigraphic schemes based on geologically significative surfaces that bound genetically related strata have not been widely adopted as the conceptual frames of reference in oilfield development in Golfo San Jorge basin. One of the main reasons for this is the unfeasibility of identifying said surfaces in the context of the basin geology, both in outcrops and in subsurface. For this reason, empirical frameworks are usually defined to divide the productive succession (600 m thick) into thinner units that contain a few tens of reservoirs. This units are bounded by surfaces not necessarily corresponding to features of geological significance, therefore providing limited interpretative potential. The need to identify analogs to mature field Sur Piedra Clavada (SPC), a highly productive, thoroughly characterized field located in the south flank of the basin, led to establish the need of a conceptual framework that accounted for observed sand bodies configuration. With gamma ray log as the main tool, periodic gamma ray log patterns variations were identified for the main productive interval (Bajo Barreal Fm.), roughly 80 m thick. Integration with detailed petrography of core and side wall cores provided the critical outlines of an interpretative stratigraphic framework. For 120 test wells, three sequences were defined, based on the presence of "sand clock" shapes successions: stacking of 20-35 m thick units bounded by laterally continuous, maximum gamma ray intervals. Limiting surfaces correspond to tuffs, vitreous sandy and clayey tuffs. Thin sand bodies tend to locate in an apparently random position while the thickest ones (probably related to different aggradation processes), are middle and upper sections of each sequence, with occasional presence of high thickness sand bodies, which probably increases interconnectivity of reservoirs. Stratigraphic units reflect the variations in the Accommodation/Sedimentation regime, controlled mainly by changes in pyroclastic input. Maximum input moment is equivalent to maximum pseudo accommodation moment, which is followed by rehierarchization of fluvial network, and eventually by incision, generating highest thickness sand bodies. The regional nature of the main controlling parameter on sedimentation strengthens analog validity for neighbor areas and allows for inference of similar reservoir configurations. The constructed Framework is currently a key support for short-term and long-term development plans for the block, providing a highly predictive conceptual background. |
