WellWatcher DTS Fiber-Optic Monitoring Systems

Wellbore temperature is continuously collected and transmitted to the surface using permanently installed fiber optic monitoring technology. Click to view Schlumberger offers multiple means of deploying a fiber into a wellbore, including fiber pumping, fiber-optic cable, and hybrid opto-electric cable.

• minimizes the need for production logs
• prevents deferred production losses
• decreases well interventions
• reduces operating costs.

• WellWatcher Neon System Product Sheet (274 KB PDF)
  Hybrid optoelectric permanent monitoring system that adds a fiber-optic DTS line to the permanent downhole cable. Distributed temperature data can be obtained on the fiber-optic DTS line at the same time that pressure data is obtained on an electrical conductor.
  
  
• WellWatcher Ultra System Product Sheet (155 KB PDF)
  Rugged DTS system that can measure up to 15 km [9.32 mi] of fiber at a meter's resolution, update data in seconds, resolve temperatures to 0.01 degC [0.018 degF], and interrogate numerous fibers from one surface system.
  
  
• WellWatcher BriteBlue ST Fiber Product Sheet (121 KB PDF)
  Harsh-environment multimode fiber used for distributed temperature sensing only or for high-speed communication between a downhole sensor and a surfaces unit in temperatures of <175 degC [347 degF].
  
  
• WellWatcher BriteBlue HT Fiber Product Sheet (249 KB PDF)
  Harsh-environment fiber designed for use in extreme heat ranging from 175 degC to 300 degC [347 degF to 572 degF] and extreme hydrogen environments.
