ZERO180™ - Gun System
ZERO180™ Gun System is specifically designed to help lower completion costs and increase production results in horizontal wells. Two primary features which differentiate the ZERO180™ gun system are:
- 1. It can orient perforations in any pre-determined direction.
- 2. It can be shot sequentially using conventional switching systems.
This allows multiple guns to be run and oriented on the same trip into the well. The ZERO180™ system can be shot using conventional conveyance systems such as wireline, coiled tubing, or tubing conveyed perforating (TCP).
- Case Study 1:
- - Hydraulic fracturing breakdown pressure reduction of 2400 psi (16.5 Mpa) with same flow rate as similar wells.
- - Open perforation flow area calculated 100% of the ZERO180™ gun oriented perforations to be open.
Case Study 2:
- - Hydraulic fracturing breakdown pressure reduction of 600 to 1200 psi (4 to 8Mpa).
Case Study 3:
- - The Zero180™ Oriented Perforating Gun System was used to Plug and Perf a horizontal shale well in western Canada.
This well utilized fiber optic located on the outside of the casing for real time monitoring, the Zero180™ perforating guns were oriented
to avoid perforating the fiber optic line. The toe of the well was perforated with Coiled Tubing deployed Zero180 perforating guns
configured with the HTD-BLAST™ time delay system. The wireline pump down Plug and Perf operation was completed with Zero180™ guns configured
with addressable select fire switches. A total of 140 Zero180™ perforating guns successfully perforated the 20 stage well while avoiding
perforating the fiber optic line.
The ZERO180™ Gun System offers:
- Accurate shot placement/Uniform hole size
- Positive orientation in deviated well bore - increased accuracy over eccentric weights bars and finned swivel subs
- Charge tube rotates independent of gun
- Charge orientation not affected by well bore debris or downhole conditions
- Does not require additional down-hole equipment
- Minimizes total gun length & connections
- Designed for stimulation/Reduced break-down and treating pressures
- Orientation adjustments to avoid control lines in smart well applications
