This project entailed perforating three zones in 7” casing that were far apart. The client wanted a reliable and cost-effective way to complete this without paying for the large blank sections between the gun system. TESL TCP team deployed three perforating systems as follows,
Zone #1
• 4.5” TCP HSD guns loaded with deep penetrating charges @ 12 spf, from 6157’- 6441’, 41’ Net, 284’ Gross
• Pressure activated firing head with a 6-minute time delay system
• Flow-debris sub
• 2 7/8” Space out tubing
Zone #2
• 4.5” TCP HSD guns loaded with deep penetrating charges @ 12 spf, from 5816’ – 5826’ 10’ Net, 10’ Gross
• Pressure activated firing head with a 6-minute time delay system
• Flow-debris sub
• 2 7/8” Space out tubing
Zone #3
• 4.5” TCP HSD guns loaded with deep penetrating charges @ 12 spf from 5333’ – 380 31’ Net, 47’ Gross
• Pressure activated firing head with a 6-minute time delay system
• Flow-debris sub
• Radioactive marker
• Tubing to Surface
All three systems were deployed on 2 7/8” tubing on a single trip. The firing systems were active via applied surface pressure and all three-gun systems activated six minutes apart, accomplishing the goal of perforating the three zones on one run
