CASE HISTORY | bakerhughes.com First Successful Deployment of Integrated Sand Control Packer and Fiber-Optic Wet Connector System Location: Gulf of Mexico As the industry has shifted to focus more closely on maximizing efficiency and production from offshore reservoirs, the need for downhole monitoring has increased substantially. Having access to continuous real-time data enables operators to enhance production and increase ultimate recovery. Two-trip completions are used to divide the completion string into an upper and lower segment. This enables operators to perform more cost-effective workovers because they can leave the lower completion in the wellbore while pulling the upper. For more than a decade, oilfield service companies and operators have made multiple attempts to design a fiber-optic wet connector monitoring system that could be successfully deployed on two-trip completions to deliver continuous and real-time monitoring across the sand face. Over a 5-year period, Baker Hughes collaborated with a major operator to develop a six-channel fiber-optic wet connect system that integrates with Baker Hughes sand control frac-pack systems. This enables the operator to disconnect from the sensors and gauges installed in the lower completion and conduct an upper completion workover. Leaving the lower completion in place during the workover reduces cost and rig time required to recomplete the well. The wet connector is then stabbed back into the lower segment along with the upper completion to resume optical monitoring across the sand face. After years of development and rigorous testing, the Baker Hughes SC-2™ feed-thru Results nnDeployed the industry’s first integrated sand control packer and fiber-optic wet connector system in a dry-tree application nnDelivered continuous and real-time monitoring across the sand face in a two-trip completion, enabling the operator to enhance production Background and challenges nnDry-tree completion in 3,000 ft of water nnOperator The Baker Hughes fiber-optic wet connector system provides real-time downhole monitoring, enabling operators to enhance production packer and fiber-optic wet connector were run as an integrated completion solution including a CK FRAQ™ frac-pack system in a dry-tree application in the Gulf of Mexico. The wet-connect system established a clean optical connection on the first attempt and continues to function fully across all six channels 20 months after installation, validating the longevity of fiber in a wet connector. The monitoring system included SureVIEW™ P/T (pressure and temperature) gauges, a dual-ended SureVIEW™ DTS (distributed temperature sensing) system, distributed strain monitoring, and included spare CoreBright™ fiber for performing needed to monitor downhole conditions and production data across the sand face in a two-trip horizontal completion extending to 17,500 ft MD Baker Hughes solutions nnInstalled an SC-2 packer equipped with a debris management system for achieving optimal downhole connections nnDeployed the integrated wet connector at 14,950 ft MD, enabling optical monitoring across the sand face nnIncluded SureVIEW P/T gauges, a SureVIEW DTS system, distributed strain monitoring, and spare CoreBright fiber for conducting SureVIEW DAS surveys CASE HISTORY SureVIEW™ DAS (distributed acoustic sensing) surveys. The SC-2 feed-thru packer included a debris management system that enabled a clean downhole connection. The wet connector was deployed as part of the completion string at a measured depth (MD) of 14,950 ft (4557 m), which enabled realtime monitoring across the sand face, and the total MD for this two-trip completion was 17,500 ft (5334 m). At the time of deployment, the integrated sand control packer and fiber-optic wet connector system accommodated six data monitoring channels extending into the lower completion. This extensive ability to provide real-time and continuous data across two-trip offshore completions enables operators to enhance production, improve workover efficiency, and increasing ultimate hydrocarbon recovery.
