Remedial solution for mining environments and water well repair
The need for a water well rehabilitation is a critical step in the life of the well.
The water well performance (flow rate and drawdown) can depreciate over time. So can the quality of the production. This declination is a natural occurrence. It is also a shared experience with mechanical structures.
Operators can costly abandon a well and drill another one. They can also opt for the casing patch option. Saltel expandable steel Patch is a reliable alternative for water well repair. The patch has the ability to expand and cover:
- Leaking casings.
- Solids producing casings.
- corroded casings.
- screen sections.
Features and benefits of repairing a damaged, leaking or corroded casing
Once installed, the Patch leaves a wide ID (internal diameter) and access to the well below for standard downhole tools. Our drift ID is
The Patch sets as a pressure resistant inner-lining. Its fit-for-basin design avoids abandonment decisions.
Once installed, the Patch leaves a wide ID (internal diameter). This ID grants access to the well below for standard downhole tools. Our drift ID is one of the biggest in the market.
Outstanding benefits with post-patch installation.
The patch restores the casing or tubing integrity. Once installed, the patch also allows a significant increase in your production rates. A water well rehabilitation with Saltel patch also avoids surface contaminants and prevents losses in the formation.
