In this seminar Dana Jurick, Chief Operating Officer of Neubrex Energy Services US LLC. discusses the collection, analysis and interpretation of strain measurements utilizing fiber optic cables.

Small chips of rocks (e.g., <1/8 inch or <3 mm) obtained during drilling with a rotary bit that are continuously returned to the surface by the circulation of mud. Drill cuttings are the main source of geological and stratigraphic interpretation in the drilling of geothermal and oil-gas wells.
Cyclone Separator A large cylindrical vessel attached to two-phase production pipelines in geothermal fields that is used to separate dry steam from a fast-moving two-phase fluid. Steam separation results from cyclonic fluid flow, centrifugal force and gravity.
DAS Distributed Acoustic Sensor. Involves the deployment of fiber optic cable on the surface or in a well, and the detection of small variations in the refractive index of the fiber based on the scattering of light pulsed from a laser. Strain and temperature can be...
DFIT Diagnostic Fracture Injection Test. A subsurface well test in which pressure is monitored as a small volume of fluid is injected into a reservoir to develop a hydraulic fracture. Monitoring continues to produce a pressure versus time plot that is analyzed to...
