At Petromac we design and manufacture a broad range of bespoke devices particularly for the wireline logging industry. Petromac devices provide a quantum improvement for both the wireline logging companies and the operators we serve to deliver significant cost and time saving benefits.

The technology has been used around the world and the success published in multiple venues after a thorough peer review.
