Subsea artificial lift systems
Harness reliable ESP technologies for subsea, deepwater, and ultradeepwater systems.
Dual electrical submersible pump (ESP) lift systems enable cost-effective production in applications where rig availability may be at a premium and where the cost of workover impacts the overall profitability of the well. Dual ESP systems can be used in series to double the horsepower in a well, or they can be used in parallel to produce independent zones. The systems can also function as an in-well backup system to reduce downtime and lost or deferred production while mobilizing workover equipment.
Our custom-designed systems encapsulate and protect ESPs in a sealed and isolated environment. Pod systems are used to isolate and produce multiple zones, configure two ESP systems in series for greater lift, or isolate and protect the casing from harsh wellbore fluids.
Schlumberger has completed more than 80 systems in offshore, deepwater, subsea, and mining applications. The success of these custom-designed systems provides a solution to previously cost-prohibitive ESP completions.
Engineered ESP technology adds production monitoring and long-term flexibility for changing reservoir conditions, Austria.
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.
ESP-related advances from Schlumberger—a dual ESP system provides either a backup in the case of primary pump failure or an improved solution for multizone production, enhanced modeling software that assists in the design of ESP and gas lift systems, and to monitor artificial lift system performance, a proprietary interpretation technique provides real-time flowrate without the need to retrofit additional hardware in the field, with the exception of downhole ESP gauges and SCADA.
When you need to improve the performance of your high-asset-value wells, Schlumberger dual ESP systems provide the power and reliability demanded in high-risk, high-cost producing wells.
