Análisis de los fluidos de control en operaciones de completación y reacondicionamiento para minimizar el daño de formación en reservorios del campo Cuyabeno-Sansahuari.

Abstract

The main objective of this work is to perform an analysis of the control fluids that are offered in the industry, from a technical point of view, in order to determine a formulation that minimizes the damage caused in completion and workover operations in the reservoirs of the Cuyabeno-Sansahuari field. During the development of this work, a description of the field in study is made, also described the characteristics of the main producing sands and the fundaments that have served as reference in the development of this work. In order to achieve this objective, the compatibility tests between control fluids and the reservoir oil are tested in the laboratories of the bidding company. A simulation test of formation damage was also performed in cores of the upper U, middle U and lower U sands, where the return permeability of the cores was measured so that allowed determinate the impact caused by the operation. Finally it presents a technical analysis of the results obtained by the experimentation in laboratories, an analysis was made by comparing IP that allowed to determinate the impact of each control fluid in the reservoirs, and recommend the optimal formulation for each producing sand. The conclusions and recommendations that were obtained from the present study are found in the final chapter.
