Abstract

The Auca Asset is made up of the Auca, Auca Sur, Tortuga, Chonta Este, Anaconda, Cononaco, Rumiyacu, Chonta Sur, Culebra, Yuca, Pitalala and Yulebra fields. In the Auca Sur field, the object of this study, 21 wells are producing from the Napo U and T, and from Hollin sandstone. Almost all of the producing wells, the lifting system used is the electric submersible pumping. This work proposes solutions to increase the production of the Auca Sur field through a nodal analysis. Before carrying out the analysis, an initial selection is made, in which wells that are producing under the electric submersible pump system are chosen. In the same way, it was important that the selected wells have updated information for subsequent analysis. For the simulation, the PIPESIM software was used, for which updated information was collected such as: PVT analysis, Build Up, petrophysical properties, core analysis, production history, surveys of directional wells, flow line data and mechanical diagrams. with which the current conditions were simulated, with the simulation of the conditions it was possible to carry out a sensitivity analysis to the properties of the production system. With the simulation and sensitivity analysis carried out on the chosen wells of the Auca Sur field, the wells that are technically and economically feasible were evaluated to carry out the optimization proposals that include: pump changes and/or increasing the frequency, resizing, etc. At the end of the technical study, an estimated increase of 1141.57 bl/d was obtained from the 4 selected wells, this increase is a representative value in technical and economic terms with respect to the actual condition of the field.
