Downhole Service Tools
Service tools are the mechanical and hydraulic tools used to run, set, test, and retrieve downhole completion equipment — packers, plugs, and cement retainers. They are not permanent wellbore components; they perform their function and are retrieved to surface for reuse. Selecting the correct service tool for each application ensures reliable tool function and reduces the risk of stuck tools or incomplete operations.
Service Tool Applications
- Setting mechanical and hydraulic packers
- Setting wireline-deployed tools using tubing-conveyed setting methods
- Pressure-testing tubing strings above set packers
- Circulating fluid above or below set packers
- Releasing and retrieving stuck or set completion tools
- Straddle testing of specific wellbore intervals

Frequently Asked Questions
Q: Do I need to order service tools with every packer order?
Setting tools are required to run and set the packer. If you already have compatible setting tools from a previous MAP Oil Tools order, they may be reused — confirm the tool-to-packer compatibility with Proxima before use. We recommend ordering a setting tool with the first order of any new packer model.
Q: What is the MTXT tubing test tool used for?
The MTXT (MAP Tubing Test Tool) allows the tubing string to be pressure-tested above a set packer — confirming tubing integrity before the well is put on production. It is a standard step in completion best practice and reduces the risk of undetected tubing leaks.
Q: Can MAP Oil Tools service tools be used with packers from other manufacturers?
MAP Oil Tools service tools are designed and dimensioned for MAP Oil Tools products. Compatibility with other manufacturers’ packers is not guaranteed. Contact Proxima if you need to run MAP service tools with non-MAP packers.
