“Historically, operators who needed to stimulate their offshore wells
were faced with complex completion operations that could take longer
than a month and with costs approaching a hundred million dollars,” said
Typically, after a deepwater well has been drilled, the subsequent completion phase involves multiple, time-consuming steps. In contrast, the DEEPFRAC service eliminates casing and cementing operations and simplifies fluid logistics by using ball-activated, multiposition sleeves that can be installed in openhole wellbores containing drilling mud. And, unlike conventional offshore systems’ complicated tool running procedures and extensive mechanical manipulation requirements, no tool movement is needed during the DEEPFRAC service’s stimulation process. The sleeve’s ball activation enables continuous pumping from the first stage to the last, cutting the lower completion phase from weeks to days.
Conventional offshore stimulation systems are often limited to only five zones or ‘stages’ and these systems lack configuration flexibility that often results in uneven treatments and creates long sections of ‘dead space’ that cover up hundreds of feet of viable pay. The sleeves used in the DEEPFRAC service are modular and flexible, enabling placement of 20+ tightly-spaced stages across the pay zone to ensure more uniform treatments and to maximize reservoir contact.
After stimulation operations are complete, Baker Hughes IN-Tallic™ disintegrating frac balls allow production to flow without intervention. Patented Baker Hughes BeadScreen™ proppant flowback control technology built directly into the DEEPFRAC sleeve’s production ports provides increased reliability over conventional sand screens through higher burst/collapse ratings and improved erosion/plugging resistance, helping to ensure long-term, sand-free production.

The DEEPFRAC service is the latest example of Baker Hughes’ strategy to improve well efficiency, optimize production and increase ultimate recovery.
