After production startup of lean and rich gas fields in Algeria, some reservoirs experienced a continuous pressure decline that affects the real production potential of many wells. To have the flexibility to treat both rich and lean gas wells [up to 100% gas volume fraction (GVF)], a new multiphase pump system has been developed by comparing the different boosting systems performance and analyzing well-by-well production scenarios. With two systems installed successfully in different configurations, all involved wells have produced with an optimized bottomhole drawdown to extend productive life.
Introduction
The gas fields are situated on the Berkine Basin in Algeria and are part of a joint commercial project. The facilities gather and process produced fluids from lean gas wells from Field B, along with rich and lean gas wells from Field A in order to produce gas, oil, condensate and liquefied-petroleum-gas products.
