Sucker-Rod Pumping Wells Optimisation Using a Spreadsheet Database on Barrow Island, Western Australia

Abstract

ABSTRACT This paper demonstrates how a carefully designed spreadsheet database can be used as an innovative tool by production engineers and field operators to optimise the performance of sucker rod pumping (SRP) wells. The spreadsheet will be available on SPE EXCHANGE DISKS for potential users. An extensive Artificial Lift Optimisation Program (ALOP) was implemented by West Australian Petroleum Pty. Limited (WAPET) in 1991 on its Barrow Island field (BWI). Any ALOP requires extensive data collection, screening, validation and continuous monitoring. BWI has over 420 active oil producers, and 350 of them are SRP wells. As part of the ALOP, WAPET decided to compile a Microsoft Excel spreadsheet database. The spreadsheet database contains all relevant individual well’s information and a comprehensive dynamometer card analysis module. Apart from individual well optimisation, the database was designed to: a)identify inefficient / low profit wells,b)rank wells according to profit generation,c)establish priorities to maximise revenue during production system upsets,d)spot and fix problems early before large production losses occur,e)evaluate and plan for long term production goals. The database provides the engineers with valuable clues indicating which wells should receive attention and where the potential for improved behaviour or increased production lies. In addition, the database provides more accurate records and better retention of the information for designing or redesigning artificial lift equipment. Without the database, engineering analysis is very time consuming. The database has greatly enhanced communication between field and central office staff. When information is required, either in the field or in the central office, the database makes it easily available. Total revenue is also increased by communicating information on production priorities in a useful format.
