Análisis del modelo planteado por la Universidad de Tulsa aplicado a una muestra de pozos con sistema de levantamiento artificial tipo jet de distintos campos del Oriente Ecuatoriano.

Abstract

In the current thesis work, an assessment of the efficiency of the model proposed by the University of Tulsa for the design of jet pumps was undertaken. Through the application of this, its suitability in analyzing the required pump power to achieve the same production flow rate was determined. This analysis was conducted on a sample of 12 wells located in the Auca, Sacha, Pucuna, and Armadillo fields in the Eastern Region of Ecuador.

For this purpose, a program was developed in MATLAB to facilitate the calculations of the Tulsa model. This computer application requests well information and provides calculation results both in a summarized format and step by step. After applying the model to the 12 wells and comparing it to their current conditions, it was observed that in 91% of the analyzed wells, optimization of power usage is achieved because the surface pump pressure is lower for the same production rate. This tool features a user-friendly interface and can be downloaded and installed on any Windows operating system, version 8 or higher.

The obtained results indicate that by employing the model proposed by the University of Tulsa for the design and selection of jet pumps in wells in the Ecuadorian Eastern Basin, the efficiency of these pumps would be improved. This would result in reduced production costs and, consequently, greater environmental and economic benefits for the country.
