Perforations are used to flow hydrocarbons into a well. Impeding that flow are damaged zones from drilling and the crushed zone lining the walls of perforation tunnels into the rock. In addition, charges can affect a region beyond the crushed zone. T

Optical fiber flatpacks, which are cable-reinforced plastic-encased fiber bundles used for local temperature and acoustic measurements, can be stressed when near a perforating gun. The fiber itself is floated in metal tubes with gel. Understanding th

A common procedure within plug-and-abandonment (P&A) application is to use explosive shaped charges deployed by hollow steel carrier perforating gun systems to perforate holes into single or multiple concentric casing strings to allow a flow path for

The nature of the crushed zone is important to the overall hydrocarbon flow following perforation. This work examines the nature of such formation damage using testing and simulation. Furthermore, the crushed zone's effect on overall formation produc

Dynamic effective stress (DES) is a consequence of dynamic underbalance (UB) (Bell 1984) created when opening a lower-pressured wellbore by means of perforation to a higher-pressure formation to promote perforation cleanup, if intentional. It pertain

The detonation of explosives in the wellbore produces hazardous gas; however, these gases are not typically observed in high concentrations at the surface. Recently, during plug and abandonment (P&A) operations, carbon monoxide (CO) from perforation

Three-dimensional (3D) finite element analysis (FEA)-based shock software is the next step in downhole shock modeling. This software uses a finite element and a fluid tool that simulates gun behavior on gun strings and adjoining tools, including perf

The understanding of perforation tunnel-flow dynamics in the presence of gravity or orientation is an important consideration. This work examines the flow dynamics after a perforation, both numerically and analytically. It presents CTH simulations of

Knowing the productivity to expect from a well is highly dependent on how deep the perforation penetrates. Besides the quality and explosive load of the shaped charge, the type of rock and the stress it is subjected to help determine penetration dept
