Revolutionizing Casing Exit Operations

Traditional window milling challenges:

-Premature cutter wear → Multiple trips per window

-Inconsistent window geometry → Stuck BHA risks

-Low ROP → 18-36 hours/window


Our solution delivers:

✅ Single-trip windows in 8-12 hours

✅ Smooth window profiles (dogleg severity <5°/100ft)

✅ Guaranteed milling length: 60-100ft per cutter set


Flow-Enhanced Chip Removal: Prevents balling up in gummy formations


Operational Advantages


✅ Unmatched Efficiency

Cut 9-5/8" casing @ 12-18 ft/hr (industry avg: 6-10 ft/hr)

Complete window in 1 trip (save 24h rig time → $120K/well)


✅ Extended Tool Life

300-400 linear ft milling per cutter set

Replaceable blades reduce tooling costs 60%


✅ Engineered Reliability

Anti-rotation locks prevent junk ring formation

Pressure-balanced for HPHT wells (20,000 psi / 175°C)



Field-Proven Applications

Deepwater Sidetracks: Single-trip exits in 10,000ft MD

Shale Multi-Laterals: 4+ windows per BHA run

Salt Dome Re-entries: Milling through corroded casings

Geothermal Wells: High-temp milling in granite formations

Case Study: Permian Basin Operator

Result: 37 windows milled with 2 cutter sets

Savings: $2.1M vs. conventional mills (60% less trips/tools)
