Product Details
Principle
By initiating a set of three collinear perforating charges (upper, middle, and lower), the jets generated by the upper and lower charges penetrate the formation at a specific angle. The resulting perforations release the formation stress between these two charges. The middle charge, detonated with a slight delay, benefits from this altered stress field. This influential factor enhances penetration depth and increases the flow area, thereby improving fluid flow performance and well productivity.
Application
low-permeability reservoir
