Record 1 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Measurements are made by a sonde as it is withdrawn from the borehole by a wire line.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.

Record 2 2004-07-20

English

Subject field(s)
  • Oil Drilling
CONT

... every operator shall take a sufficient number of types of porosity-measuring wireline logs in any well so that any effect of shaliness, hydrocarbons, complex lithology and the walls of the hole can be compensated for in determining the porosity of any formation.

OBS

wireline log: A continuous measurement of formation properties with electrically powered instruments to infer properties and make decisions about drilling and production operations. The record of the measurements, typically a long strip of paper, is also called a log. Measurements include electrical properties (resistivity and conductivity at various frequencies), sonic properties, active and passive nuclear measurements, dimensional measurements of the wellbore, formation fluid sampling, formation pressure measurement, wireline-conveyed sidewall coring tools, and others.

Key term(s)
  • porosity measuring wireline log

French

Domaine(s)
  • Forage des puits de pétrole
CONT

[...] l'exploitant réalise un nombre suffisant de types différents de diagraphies de porosité dans un puits pour que tout effet attribuable à la présence d'argiles, aux hydrocarbures, à une lithologie complexe ou aux parois du trou puisse être corrigé lors du calcul de la porosité de la formation.

OBS

diagraphie: Ensemble d'enregistrements électriques, acoustiques, gammamétriques effectués au cours des forages.

Record 3 2004-07-12

English

Subject field(s)
  • Oil Drilling
DEF

A continuous measurement of formation properties with electrically powered instruments to infer properties and make decisions about drilling and production operations ...

CONT

A log is the recording of one physical property of the formation crossed through by a borehole or of the geometric characteristics of the hole or casing or the flow behavior of a well as a function of depth. Wireline logging is performed with a sonde or probe lowered into the borehole or well, usually after the drillstring has been withdrawn.

OBS

Measurements include electrical properties ... sonic properties, active and passive nuclear measurements, dimensional measurements of the wellbore, formation fluid sampling, formation pressure measurement, wireline-conveyed sidewall coring tools, and others. In wireline measurements, the logging tool (or sonde) is lowered into the open wellbore on a multiple conductor, contra-helically armored wireline. Once lowered to the bottom of the interval of interest, the measurements are taken on the way out of the wellbore. This is done in an attempt to maintain tension on the cable (which stretches) as constant as possible for depth correlation purposes ... Most wireline measurements are recorded continuously even though the sonde is moving.

French

Domaine(s)
  • Forage des puits de pétrole
DEF

Mesure des propriétés physiques des couches géologiques traversées dans le puits à l'aide d'un câble transmettant l'information à un appareil enregistreur en surface [...]

CONT

Afin d'assurer une bonne évaluation d'un puits, l'exploitant prend un nombre suffisant de diagraphies au câble pour [...] évaluer correctement toutes les parties non tubées du puits [...] permettre un calcul précis de la porosité, de la saturation et des niveaux de contact entre fluides de tous les réservoirs potentiels [...] déterminer le diamètre du trou ainsi que le potentiel spontané et la radioactivité naturelle de toute formation [...] aider à déterminer la lithologie de toute formation [...] permettre de calculer avec précision l'angle vertical et la direction du trou et le pendage des formations [...]
