In-situ gas lift (or auto gas lift) systems consists of a single well that penetrates both gas and oil formations.
They utilize the gas zone as the source of lift gas for the oil zone. Gas supply, its corresponding infrastructure, and compression capabilities are no longer required. This offers significant capital savings, weight reduction, footprint reduction, and reduced Green House Gas emissions. It also accelerates field development by eliminating the construction and integration of a surface gas delivery infrastructure.
Successfully operating In-situ gas lift wells requires interventionless adjustments of the lift gas to accommodate changes in liquids production or formation pressures. Silverwell’s DIAL system enables this by providing a combination of surface control for downhole gas injection as well as pressure monitoring to provide a window to well conditions. Together, these provide a closed-loop system for in-situ well optimization.
Enable and accelerate development in areas with little infrastructure in place
Less GHG emissions, personnel involvement, and construction requirements
Suitable for applications where the operator desires to optimize production, drawdown, or satisfy any other well or field constraints
