Paper presented at the International Petroleum Technology Conference, February 12, 2024
Paper Number: IPTC-24199-MS
... Abstract Formation damage in the near wellbore region, causes impairment to fluid flow, perforations are designed to bypass the near-wellbore drilling damage by generating deep perforation tunnels and bypassing the damaged zone, however, perforation tunnels are affected by additional damage...

... and radially transferred to the formation through casing and cement, which generates additional stresses over the wellbore-perforation interface (see Figure 4 ). And third, injected fluid flows into the perforation tunnel from casing and maintains pressure P perf acting on the perforation wall, which...

... that are oriented toward the direction of maximum horizontal stress showed higher stability. Since the minimum horizontal stress component acts as main force on the perforation tunnel, which gives more, roam for perforation stability. The perforation was performed at optimum orientation of 170 deg Azimuth...

... computed tomography (CT) scan images were not only used to measure an accurate penetration depth and perforation tunnel dimensions, but also to provide a 3D view of the resulting perforation tunnel for qualitative analysis. Penetration depths were obtained as a function of pore pressure up to 32,000 psi...
