The Hydraulic Tubing End Locator (TEL) give the operator the ability to correlate tool string depth by locating on either the tubing entry guide or a nipple profile within the well bore.
As the tool is hydraulically operated, it can be functioned multiple times to ensure accurate depth correlation.
Flow through the tool creates the required hydraulic pressure to activate the locating arms. An over-pull will be observed when the tool is pulled through a restriction such as a nipple profile or when re-entering the production tubing. The locating arms will collapse when a predetermined force is applied. The pull force required is variable depending on pump rate and pressure.
The locating arms will retract to the tool OD when flow through tool has stopped. A safety shear release feature is incorporated in the unlikely event that the spring does not fully retract the locating arms or can also be used to de-activate the tool when it is no longer required.
