Development of a Computer program for estimating the bottomhole pressure from dynamic fluid level measurements for a pumped well under multiphase flow

Abstract

This paper presents the results obtained from the development of a program for calculating the bottomhole pressure. The program allows to simplify the measurements in the well and minimizes costs by avoiding stop production in order to obtain the required data. In the development of this work is used a method to calcúlate the flowing bottomhole pressure, from fluid level measurements. Using models to characterize the multiphase flow in a well, experimental work and theoretical arguments, the calculation procedure allows to calcúlate the flowing bottomhole pressure, without shutting the well. Also this method allows to take into account real geometry of the well. The validation of the results is based on experimental data found in the literature and real fleld data, the comparison allows us to make a proper evaluation of this model.
