Abstract
The use of foamers to remove water from wells that are challenged by hydrostatic head pressure is common practice. The success of the process, however, is predicated on the proper selection of candidate wells, the proper selection of foaming agent, and application.
Foam assisted lift does not work on all wells. At a time when resources are in short supply, dividends are returned by applying resources to candidate wells that have been thoroughly screened to improve the success rate related to foam assisted lift technology. Properly formulated foaming agents will offer better value and return on investment than marginally performing products. Comprehensive evaluation of the application is critical to achieving the desired results of a foam assisted lift program.
Experience has demonstrated the importance of selection and application to the success of foaming agents. Foam assisted lift for economical production of adolescent and mature wells adds tremendous value and is a viable alternative for challenges related to liquid loading. Continuous improvement based on well changes must be considered as a significant part of the process.
Adopting a comprehensive process related to a deliquification strategy will allow for extended success of foam assisted lift programs, improved production rates and revenue, and improved resource utilization related to a better return on capital and resources expended.
