摘要

With plunger lift being a highly recognized method of artificial lift for unloading wellbore fluids from oil and gas wells, many new and old equipment designs are being introduced or re-introduced into the plunger lift market. Several novelty-type designs have been tested and have had narrow operating windows. Most apply only during certain periods of the well's economic depletion cycle. Free cycling of a plunger is probably the oldest plunger lift methodology that has gained high recognition over the past 5 years but has the narrowest operating window of all plunger lift methodologies. Due to the narrow operating window of most of the new and old designs, that window has forced International Lift Systems to think out of the box for new designs and methodologies of producing the wells via the use of plunger lift. One of the most recent equipment designs and methodologies that promises to widely open the operating window of plunger lift is staged plunger lift (SPL). This article presents a study of the application of SPL to wells that did not previously meet the operating criteria for plunger lift. It also addresses extending the economic depletion of wells currently being produced by plunger lift.
