Introduction

Foam flow is the most suitable artificial lift method for many tight, deep, gas wells

No correlation exists for pressure drop prediction in foam flow

Need a model to correctly predict the rate-pressure drop relationship under foam flow conditions

Need to know the limits of foam flow application

background
Background

This project is a joint effort between funding by RPSEA and six companies

The six member companies are: Chevron, Marathon, Shell, ConocoPhillips, Nalco, and MultiChem

The Project got officially kicked off in December, 2010 and have been extended through December of 2014

objectives of the project
Objectives of the Project
  • Collect experimental foam flow data under controlled conditions for two different tubing sizes and five different foams
  • Measure surface tension, viscosity and foam stability
  • Develop comprehensive correlation to predict pressure drop under foam flow conditions
  • Develop guidelines for using appropriate concentration of surfactant as well as minimum gas-liquid ratios
  • Validate the model by comparing the results with field data provided by participating companies
current status
Current Status
  • Three graduate students are working or have worked on the project
    • Shu Luo – PhD Student, (finished Dec 2013)
    • Ayantayo Ajani – PhD Student
    • Anton Skopich – MS Student (finished Dec 2012)
current status1
Current Status …
  • The project is divided into three phases
    • Experimental data in large scale facility
    • Experimental data in small scale facility
    • Modeling of the data
current status2
Current Status …
  • We have collected data in large scale facility for three different surfactants and at various concentrations
  • We have collected data in small scale facilities for three surfactants at various concentrations. In addition, we have also collected data including effects of brine concentration and temperature
  • A new definition of liquid loading is introduced and a new method to predict liquid loading has been proposed. The method is validated with large amount of field data.
future work
Future Work
  • Data will be collected on two additional surfactants in both small scale and large scale facilities
  • Model will be built to estimate gas holdup in large scale facility based on small scale data
  • Model will be built to understand the inception of liquid loading under foam flow
  • Model will be built to estimate pressure drop for foam flow conditions
