At Petromac we design and manufacture a broad range of bespoke devices particularly for the wireline logging industry.

Petromac Wireline Express^TM devices have made a quantum leap in wireline operations, setting world records for deviation and depth achieved during gravity decent in open hole. In doing so, Petromac devices have enabled significant cost and time saving benefits for both the wireline logging companies and the operators we serve.

In addition, Petromac’s Focus^TM Precision Centralisers, which include the world’s first open hole roller centraliser and cased hole Rocker^TM centraliser, are revolutionising centralisation in both open and cased hole logging.
