DataSphere® ROC™ Permanent Downhole Gauges

Reliably Monitor Downhole Conditions

Halliburton's DataSphere® ROC™ permanent downhole gauges (PDGs) help increase productivity through the life of the well or reservoir by providing reliable, real-time permanent data about downhole conditions. Based on an industry-standard, field-proven resonating quartz crystal sensor, ROC gauges can be used for single- or multi-zone monitoring applications. In multi-zone applications, variations of the standard gauge are available, along with dual, triple and quad splitter block assemblies for multi-drop capabilities.

 Halliburton has installed more than 2000 ROC permanent gauge systems – both as standalone systems and as integrated components of a SmartWell® completion – worldwide.
