Hydraulic Stage Cementing Tool

The COS Hydraulic Stage Cementing Tool is engineered to meet the challenges of primary cementing in deep vertical, deviated, and horizontal wells. Using a hydraulically opened port system, it reduces hydrostatic pressure on weak formations, preventing lost circulation and improving cement placement efficiency.

Key Benefits

• Enables safer, more efficient multi-stage cementing in challenging well conditions
• Reduces hydrostatic pressure on weak zones, minimizing risk of lost circulation
• Adjustable opening pressure at rig site for maximum operational flexibility
• Clear surface pressure indications for reliable tool activation
• Improves cement placement and zonal isolation in long casing runs

Features

• Hydraulic port system designed for angled, horizontal, and deep-well completions
• Adjustable opening/closing pressure to match specific well requirements
• Clear surface indications ensure safer operation and better control
• Rugged design built for reliability in harsh downhole conditions
• Available sizes: 4 ½” to 13 3/8” (custom sizes available on request)

Applications

• Primary cementing in highly deviated and horizontal wells
• Deep vertical wells with weak or fractured formations
• Multi-stage cementing where pressure reduction and precise control are required
