Record 1 2015-04-24

English

Subject field(s)
  • Geophysics
  • Scientific Measurements and Analyses
  • Geological Research and Exploration
  • Geological Prospecting
DEF

A radioactivity logging method used in boreholes in which a neutron source provides neutrons which enter rock formations encountered and induce additional gamma radiation which is measured by use of an ionization chamber.

CONT

... neutrons can be emitted from a substance when its nucleus is penetrated by gamma particles from a highly radioactive source. This property is used in neutron logging.

OBS

The gamma radiation so induced [by the neutrons which enter rock formations] is related to the hydrogen content of the rock.

Domaine(s)

Record 2 2000-04-26

English

Subject field(s)
  • Geophysics
  • Geological Prospecting
DEF

A radioactivity log curve that indicates the intensity of radiation (neutrons or gamma rays) produced when the rocks in a borehole are bombarded by neutrons from a sonde. It indicates the presence of fluids (but does not distinguish between oil and water) in the rocks, and is used with the gamma-ray log to differentiate porous from nonporous formations.

French

Domaine(s)
  • Géophysique
  • Prospection géologique
DEF

Enregistrement continu de la teneur en hydrogène des couches rencontrées au cours d'un sondage pour la recherche d'hydrocarbures.

CONT

Semblable dans sa conception au diagramme de rayons-gamma, le diagramme neutron emploie une source de rayonnement (en général le béryllium) et n'est pas gêné par le tubage qui a été descendu dans le trou.
