Stage Simulation Tool
Brand: Wellfirst LPThe Stage Stimulation Tool (SST) is a cup-type packer assembly specifically designed to isolate and selectively acidize predetermined intervals of perforations.
The SST can be set to isolate an interval as small as 12 inches. The specially designed cups and a large built-in annular by-pass, make the SST easy to run and retrieve.
Drag blocks, using Inconel springs, provide drag for a positive method of opening and closing the by-pass valve. The SST uses a retrievable drop bar to blank off the bottom of the tool.
If used in highly deviated wells, a blow plug may be substituted.
Features- Long-lasting, heavy-duty, basket-type casing cups with full backup
- Simple operation
- Retrievable drop bar
- If required, a drop bar may be retrieved on wireline
- Large interval by-pass for ease of running and pulling
