Subsea artificial lift systems
Harness reliable ESP technologies for subsea, deepwater, and ultradeepwater systems.
The Y-tool and bypass system provides access to the reservoir below the ESP, enabling stimulation, logging, and other interventions with wireline or CT without the need to retrieve the completion. It also provides a method to configure more than one ESP in a well to accomplish production goals.
The Y-tool is installed on the production tubing, providing two separate conduits. One conduit is concentric with the production tubing and enables access to the reservoir below the ESP. The second conduit is offset and used to support the ESP system.
The Auto Y-Tool system is an addition to the ESP bypass product range. Consisting of a spring-loaded diverter valve that seals off the bypass tubing whenever the pump is running, the system saves time in wireline and CT operations, typically reducing the number of runs by two for any given well intervention.
The system is automatically closed by the flow produced by the downhole pump. However, the diverter can be locked in the open position to enable logging while the pump is running.
Switching between an upper and lower ESP also does not require an intervention. Simply stopping one ESP and starting the other will cause the diverter to switch positions, allowing production from the selected ESP while eliminating fluid recirculation.
New technology uses a shrouded ESP to draw water away from the oil/water contact, reducing coning and increasing oil production by 15%, Kuwait.
Engineered ESP technology adds production monitoring and long-term flexibility for changing reservoir conditions, Austria.
Schlumbergers new production life cycle management service, which provides real-time data collection, monitoring, analysis and interpretation to optimise the performance of artificial lift systems, has helped Agiba Petroleum Company to increase production and reduce costs.
Backup ESPs maintain production and enable optimal use of one available rig, increasing cash flow by USD 15 million in one well using the backup ESP.
