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.
Helium Isotopes
Helium gas is a trace constituent of groundwater and thermal fluids, and the ratio of 3He to 4He can be measured with a high-precision mass spectrometer to determine whether it is derived from air, from the radioactive decay of uranium and thorium in the crust, or from the mantle. The latter is a characteristic feature of volcanic and geothermal gases.
Geothermal Glossary
Word of the Week – Cyclone Separator
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.
Word of the Week – DAS
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...
Word of the Week – DFIT
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...
