Onshore shale techniques can boost deepwater fracturing efficiency
Baker Hughes's DeepFrac, a deep-water multistage fracturing service, uses multi-position sleeves and flow-back control technology to stimulate over 20 stages, boosting reservoir contact with reduced rig time. Standard multi-zone completion systems are less time-efficient, more expensive and can only treat a small number of zones. There is "a line of sight to an unlimited number of stages", said Jim Sessions, vice-president for completions at Baker Hughes.
Conventional multi-zone completion systems have several fundamental problems. They are time-consuming, costly, and treat only a small number of zones, which can lead to uneven coverage across the reservoir.

“Imagine the impact across the entire pay section if you can have 20 stages instead of just four,” says Jim Sessions, vice president for completions at Baker Hughes, a GE company (BHGE).

A new deep-water multistage fracturing service called DeepFrac from BHGE uses multi-position sleeves and flow-back control technology to rapidly stimulate more than 20 tightly placed stages, increasing reservoir contact with reduced rig time.
