SELECTIVELY ANGLED PERFORATING

A method of perforating a wellbore by forming a perforation that is aligned with a reservoir characteristic, such as direction of maximum stress, lines of constant formation properties, and the formation dip. The wellbore can be perforated using a perforating system employing a shaped charge, a mech...

Summary:A method of perforating a wellbore by forming a perforation that is aligned with a reservoir characteristic, such as direction of maximum stress, lines of constant formation properties, and the formation dip. The wellbore can be perforated using a perforating system employing a shaped charge, a mechanical device, or a high pressure fluid. The perforating system can be aligned by asymmetric weights, a motor, or manipulation from the wellbore surface. Procédé de perforation d'un trou de forage par création d'une perforation alignée avec une caractéristique d'un réservoir, telle la direction de contrainte maximale, les lignes correspondant à des propriétés de formation constante, et le pendage de la formation. Le trou de forage peut être foré via un système de perforation utilisant une charge creuse, un dispositif mécanique, ou un fluide haute pression. Le système de perforation peut être aligné par des poids asymétriques, un moteur, ou par manipulation depuis la surface du trou de forage.
