Schlumberger said Dec. 8 that it has released its OPTICall thermal profile and investigation service. This new distributed temperature sensing service tracks fluid movements in real time along the wellbore, helping to detect leaks, monitor gas lift and evaluate fractures to improve field productivity. The OPTICall service is enabled by OpticLine fiber-optic line, which provides a thermal profile along the entire length of the line continuously in realtime, providing immediate answers on site. This fiber-optic line, which is deployed in a single run using slickline-type intervention, monitors dynamic temperature events with minimal interference. OpticLine can also run conventional production logging tools in memory mode while monitoring, for single-trip efficiency. For more information visit www.slb.com/OPTICall.
