Overview
Dissolvable bridge plugs provide reliable temporary zonal isolation for well completion, pressure testing, cementing, and intervention operations while eliminating conventional drill-out. Magnesium-alloy composition and tool configuration are selected for the target temperature, fluid chemistry, and isolation window. Frac-plug and bridge-plug terminology can overlap in the market; this page focuses on bridge-plug and temporary-isolation applications.
Key Features
- Controlled-dissolution magnesium alloy selected for the well environment
- Temporary zonal isolation without drill-out operations
- Available configurations rated up to 70 MPa (approximately 10,000 psi)
- Operating envelope from 30°C to 150°C, depending on configuration
- Single-slip, double-slip elastomer-sealed, and all-metal architecture routes
- Representative casing programs include 4-1/2", 5", and 5-1/2"
- Dissolution window confirmed against the actual temperature and fluid chemistry
