The present work deals with an interpretation of well log data (gamma ray (GR), resistivity, density, and neutron) from four wells, namely P-1, P-2, P-3 and P-4 in the study area of the Rio Del Rey basin. The well logs analysis indicates five potential sandstone reservoirs at the P-1, two at the P-2, four at the P-3 and six at the P-4. The neutron–density-GR logs highlight the sandstone gas reservoir characterized by high resistivity and crossover between neutron density. The neutron–density-GR cross-plot confirms the presence of sandstone containing hydrocarbons by a displacement of the cloud of points, from low to medium GR values, from the sandstone line to the left. Petrophysical parameters exhibit the value 12–41% for a volume of shale, 15–34% for effective porosity, 29–278 mD for permeability and 3–63% for water saturation. The three potential hydrocarbon reservoir saturation ranges from 22 to 45%. The study will contribute to future offshore oil and gas exploration and development in the Rio Del Rey basin, based on the geological and geophysical characteristics of the reservoirs delineated.

目前的工作涉及对来自研究区的四口井，即 P-1、P-2、P-3 和 P-4 的测井数据（伽马射线 (GR)、电阻率、密度和中子）的解释。里奥德尔雷盆地。测井分析表明 P-1 有五个潜在的砂岩储层，P-2 有两个，P-3 有四个，P-4 有六个。中子密度-GR测井突出显示了具有高电阻率和中子密度交叉的砂岩气藏。中子-密度-GR 交会图通过从砂岩线向左移动点云，从低到中 GR 值，证实了含碳氢化合物的砂岩的存在。岩石物理参数的值对于页岩体积为 12-41%，有效孔隙度为 15-34%，渗透率为 29-278 mD，含水饱和度为 3-63%。三个潜在的油气藏饱和度范围为 22% 至 45%。根据划定的储层的地质和地球物理特征，该研究将为 Rio Del Rey 盆地未来的海上油气勘探和开发做出贡献。
