A recent perforating job utilizing a 6 SPF, zero-phase perforating gun run in combination with a Mechanical Orienting Tool (MOT) to achieve precise, selective perforation.

Objective:
Ensure the sand of interest is perforated while avoiding perforation of the long string tubing, as the entire tool string was conveyed through the short string tubing.

How it was achieved:
-The MOT notch was accurately aligned with the zero-phase scallops of the perforating gun.
-Prior to detonation, a station log was acquired to confirm correct orientation.
-The log clearly showed metal thickness variations, where:
-High peaks represent casing
-Low peaks represent the long string tubing

This verification ensured confident and safe gun firing with precise directional control.

Tool String Configuration:
Cable Head → Weight Bar → CCL → CENt → MOT → Shock Absorber → Firing Head → Perforating Gun → Bullnose

A great example of how orientation control, logging verification, and proper tool string design come together to deliver accurate and damage-free perforating operations.
