Deep Penetrating Charge 1
Deep Penetrating Charge 1 : (n.) Perforating. A perforating charge designed to provide a long perforation tunnel, such as may be required to bypass any near-wellbore damage. Specially designed deep-penetrating charges achieve this additional length while retaining a medium-sized entrance hole, an important consideration in high-shot density applications.
