Wellbore Flow Simulation: Study Cases of Several Mexican Wells

Abstract

In this work, a description is given of several wellbore flow simulation cases. These include prediction and match with measured pressure and temperature profiles of well H-17 from the Humeros GF after repair and deviation of from the vertical; calculation of the productivity index of well Az-45 from the Azufres GF; prediction of production characteristics of well M-201 of Cerro Prieto Geothermal Field (CPGF); explanation of the sudden death of well M-202 of CPGF. Simulation was performed using GEOPOZO, a general purpose wellbore flow simulator developed jointly by the Instituto de Investigaciones (IIE) and the Comision Federal de Electricidad of Mexico (CFE) as a tool for everyday routinary use. GEOPOZO assumes homogeneous flow and is quite versatile, fast and easy to use. GEOPOZO has found wide application in the Mexican geothermal fields and experience gained through its use has proven its reliability in a wide range of applications.
