Reliability Improvement in Beam Pumps by Use of a Unique Methodology

Fig. 1—Santos’ Cooper basin beam-pump parted-rod-failure frequency (2008 to 2013). Wells with automation installed have a lower failure frequency than wells with no automation.

This paper focuses on analysis of beam-pump-failure root causes and trends and how the operator has used these data combined with automated equipment to reduce failure frequency and operating cost. The paper also presents data and findings to support the benefits of a beam-pump-automation and -control program.

Introduction

The operating company has operated a fleet of beam pumps in the Cooper basin in central Australia since 1985. The basin extends over 30 000 km2 in a remote, harsh, arid desert. Ambient air temperature can range from 0°C to greater than 50°C, and there is potential for flood events in the wet season. The remote location and variety of weather conditions present numerous operational challenges and technical constraints. Historically, the beam pumps have run in a traditional manual mode whereby production operators measure, record, and analyze operating parameters and monitor surface-equipment condition. The operator implemented an automation program in 2006 to help improve run life; increase production; and decrease environmental, health, and safety risk.
