| Summary: | An hydrocarbon reservoir was characterized via a detailed geologic model, which allowed estimation of the original oil in place. The study characterizes a hydrocarbon reservoir of two fields of unit C7 of the Carbonera Formation within the Llanos Orientales basin of Colombia. This was done using well logs, the structural surface of the regional datum of the area, segments of the Yuca fault and a local fault of the reservoir, the permeability equation, and J functions of the reservoir provided by the operating company. With this information, a two-fault model and a grid with 3D cells was created. Each cell was assigned with a value of facies and petrophysical properties: porosity, permeability, and water saturation, to obtain a 3D model of facies and petrophysical properties. Subsequently, we used the constructed models and oil-water contacts to calculate the original oil in place for each field. Field 1 has a volume of six million barrels of oil and field 2 has 9 million barrels.
