World Oil: What’s New In Artificial Lift?

In recent years, ESPs have been the fastest-growing form of artificial lift, partially due to their ability to operate across a broad range of flowrates and depths. Slimline ESP improves production and system reliability in small-diameter wells. Unconventional resource operators often opt to drill smaller-diameter wells or install heavier wall casing to lower drilling costs, optimize the completion design, increase the collapse pressure, or improve wellbore stability. While all of these factors can have a positive economic and technical impact, the resulting well can pose challenges during the production phase. Unconventional wells have rapidly declining production rates and high levels of gas and solids entrained in the fluid stream. Smaller wellbores limit artificial lift options that can handle these issues. Thus, operators often sacrifice production and ultimate recovery. Click the link below to read the full article.
