Operation
Used to select the correct finger size and install it into the slotted housing. Install a brass shear pin into the slotted housing.
The tool string and tubing end locator are lowered down the well.
As the tool passes through the tubing bottom, the finger will rotate out from a compressed position to a horizontal
position resting on the shear pin.
Raising the tool string until a weight increase appears on the weight Indicator. This indicates the tubing bottom depth.
The tool string is now lowered approximately two meters, and accelerated
up quickly. This will strike the finger on the tubing bottom and shear the shear pin. The shear pin may also be sheared with the use of hydraulic jars.
When ran in conjunction with a sample bailer, a sample from total depth of
the well can be obtained. Delivering a few light downward jars sinks the sample bailer into the bottom of the well to catch a sample.
NOTE
When total depth measurements are critical the depth can be correlated
to well file information to correct any errors of line measurement from zero depth.
