Dans l'industrie pétrolière et gazière, la perforation est une étape cruciale de la complétion de puits. Elle consiste à créer des trous dans le tubage et le ciment pour permettre aux hydrocarbures de s'écouler dans le puits. **Le contrôle de profondeur de perforation** fait référence à la méthode précise d'alignement et de tir du canon de perforation à la profondeur souhaitée dans le puits. Cela est essentiel pour optimiser la production et minimiser les risques potentiels.
