CA 2618128

Disclosed herein is a method comprising disposing in a formation fracture, a proppant and/or a fracturing fluid that comprises a radiation susceptible material that comprises indium and/or vanadium; irradiating the radiation susceptible material with neutrons; measuring gamma-radiation emitted from the radiation susceptible material in a single pass; wherein the single pass does not involve measuring of background radiation from previous or subsequent logging passes; and determining formation fracture height from the measured gamma-radiation.

La présente invention concerne un procédé qui consiste à placer dans une fracture de formation un agent de soutènement et/ou un fluide fracturant qui comprend un matériau susceptible de rayonnement comprenant de l'indium et/ou du vanadium, à irradier ce matériau susceptible de rayonnement avec des neutrons, à mesurer le rayonnement gamma émis par ce matériau susceptible de rayonnement en une seule passe, cette passe unique ne consistant pas à mesurer un rayonnement de fond en provenance d'une passe précédente ou de passes d'enregistrement suivantes et, à déterminer la hauteur de la fracture de formation à partir du rayonnement gamma mesuré.
