Thru Tubing Packer Manufacturer | Coiled Tubing Intervention Tools | ASBR

The Thru Tubing Packer is a highly efficient downhole support system for low-pressure gas well stimulation. It allows for a stable tubing string to be suspended inside the production tubing, which significantly improves the gas well's ability to carry liquids and restores stable wellbore production. This system is typically run into the wellbore with coiled tubing or conventional tubing, where a setting tool performs the setting, releasing, and other steps to position and activate the string.

Once set, the packer can function as a stable production string. Later, a conventional or coiled tubing string with a GS-type fishing tool can perform a mechanical release to retrieve the entire packer assembly, which is useful for maintenance or adjusting wellbore conditions.

Compared to traditional surface-hung velocity string technology, this in-tubing suspension method effectively shortens the coiled tubing length between the packer and the wellhead. This reduces material and construction costs. It also offers quick deployment, reliable setting, and smooth release, making it suitable for old wells or low-pressure wells that need rapid stimulation and technological upgrades.

Product Features

·       In-Tubing Setting: Sits inside the tubing, eliminating the need for a surface suspension device for a simpler structure.

·       Flexible Deployment: Can be run with either coiled tubing or conventional tubing.

·       Mechanical Activation: Both the setting and release processes are mechanically activated for high operational reliability.

·       Cost-Effective: Shortens the required length of coiled tubing, significantly reducing overall construction costs.

·       Reusable: Supports repeated retrieval and replacement, suitable for periodic maintenance of old wells.

·       Boosts Production: Effectively improves the liquid carrying capacity of low-pressure wells, helping to restore gas well productivity.
