Baker Hughes announced the introduction of its DEEPFRAC deepwater multistage fracturing service, which can save operators hundreds of millions of dollars in offshore developments through unprecedented efficiency gains across the completion phase. Using multiposition sleeves and patented flowback control technology, the service accelerates or eliminates certain steps of conventional multizone completion operations and enables rapid stimulation of 20+ stages. This translates into significantly greater reservoir contact, with an average OPEX savings of USD 30 to 40 million per well. Proprietary flowback control media is incorporated directly into the multiposition sleeve’s production ports to enable long-term, sand-free production without the need for conventional sand screens. 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. 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.
