Record 2 2010-12-17

English

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

A record of the measurement of porosity done by comparing depth to the time it takes for a sonic impulse to travel through a given length of formation.

OBS

First used for seismic-velocity information, it is now used chiefly for estimating porosity and lithology by the empirical Wyllie time-average equation.

OBS

Usually measured in microseconds per foot.

OBS

sonic log; continuous-velocity log; velocity log; sonic well-log: terms used at Natural Resources Canada - Earth Sciences Sector.

Key term(s)
  • transit time log
  • sonic well log

French

Domaine(s)
  • Géophysique
  • Prospection géologique
  • Mesures et analyse (Sciences)
DEF

Enregistrement de la vitesse du son.

CONT

La diagraphie sonique a maintenant de multiples applications pour : trouver la porosité dans des sondages remplis de liquide; déterminer porosité, lithologie et argilosité en conjonction avec les diagraphies de densité et de neutron; fournir la vitesse des formations pour les interprétations sismiques [...]

OBS

Une diagraphie sonique est l'enregistrement du temps d'arrivée de l'onde acoustique à deux distances fixes d'un émetteur.

OBS

Record 3 2010-12-10

English

Subject field(s)
  • Geophysics
  • Geological Prospecting
  • Oil Drilling
DEF

A graphic record of the measured or computed physical characteristics of the rock section encountered in a well, plotted as a continuous function of depth.

OBS

Measurements are made by a sonde as it is withdrawn from the borehole by a wire line. Several measurements are usually made simultaneously, and the resulting curves are displayed side by side on the common depth scale.

OBS

well log; borehole log; borehole survey; wire-line log: terms used at Natural Resources Canada - Earth Sciences Sector.

French

Domaine(s)
  • Géophysique

Record 4 2007-09-17

English

Subject field(s)
  • Oil Drilling

DEF

A record kept on the rig for each tour to show the footage drilled, drilling fluid tests, bit record, and other noteworthy occurrences.

CONT

A well log is a detailed foot-by-foot record of the rock formations encountered during the drilling of a well. It provides information on the character, depth location, thickness and nature of the rock strata and sedimentary beds drilled through, as well as the location and thickness of water sands, oil sands, and gas sands.

OBS

borehole log; well log: terms used at Natural Resources Canada - Earth Sciences Sector.

Record 7 2000-01-26

English

Subject field(s)
  • Geophysics
  • Geological Prospecting
DEF

The generic term for a well log that displays electrical measurements of induced current flow (resistivity log, induction log) or natural potentials (spontaneous-potential curve in the rocks of an uncased borehole.

CONT

An electric log typically consists of the spontaneous-potential (SP) curve and one or more resistivity or induction curves. The Archie equations form the basis for interpretation of electric logs.

OBS

elec log: ... abbreviation for electric log; used in drilling reports.

OBS

resistivity log: As a spontaneous-potential curve is commonly present in resistivity logs, the term resistivity log is often used as a synonym of electric log, but it is an informal synonym.

French

Domaine(s)
  • Géophysique
  • Prospection géologique
DEF

Enregistrement des résistivités ou des conductivités des formations et des potentiels spontanés qui prennent naissance dans les sondages.
