Abstract: Wireline saver tool assemblies may be used for oil and gas operations. In some cases, the wireline saver tool assemblies may provide a mechanical catch for a wireline saver tool for minimizing and/or preventing the wireline tool from falling freely from a lubricator in the event of an operator and/or equipment failure. Operator input may not be required to catch and/or prevent falling of the wireline tool.

Abstract: A method for calibrating the sensors present within a drilling tool, whereby the calibration occurs downhole and in-situ within the drilling tool.
