tracer measurement
Oil & gas; Oilfield
A technique in which a tracer is injected into the flow stream of a production or injection well to determine fluid paths and velocities. Radioactive tracers have been used from ...
chemical-marker injection
Oil & gas; Oilfield
A technique in which a slug of material is introduced into the flowstream of a producing well to determine the flow rate of one or more of the fluids. The marker has specific ...
shifted spectrum
Oil & gas; Oilfield
A technique in nuclear magnetic resonance (NMR) logging based on the shift in the T 2 distributions, or spectra, acquired with different echo spacings. The technique is usually ...
differential spectrum
Oil & gas; Oilfield
A technique in nuclear magnetic resonance (NMR) logging that is based on the difference between the T 2 distributions, or spectra, acquired at different polarization times. The ...
enhanced diffusion
Oil & gas; Oilfield
A technique in nuclear magnetic resonance (NMR) logging based on a long echo spacing, specially chosen to enhance the diffusion of formation water. Echo spacings in standard NMR ...
spectral density analysis
Oil & gas; Oilfield
A technique for utilizing fractal geometry to produce reservoir descriptions.
X-ray diffraction (XRD)
Oil & gas; Oilfield
A technique for the semiquantitative mineralogical analysis of a sample of rock by measuring the diffraction peaks in X-rays diffracted by the sample. The position of the ...
