Self-Release Cementing Stage Tool
Self-Release Cementing Stage Tool
The Self-Release Cementing Stage Tool is used in stage cementing applications. With featured self-released mechanical design, the innards of the tool can be released and free falling to bottom of the well, thus full bore is achieved and drill out operation is eliminated. This technology saves both time and money, and reduces intervention risk.
