SWM began as an entity in 1979 with humble beginnings as a small owner operated welding shop. Expanding from casing gun repairs for local wireline companies, SWM began to add additional gun servicing equipment and perforating resale products. Beginning in the early 1999, SWM began manufacturing their own perforation gun systems.

SWM’s prewired, disposable gun systems build on its experience designing and manufacturing more than 10 million perforating gun systems. The advanced systems eliminate wiring guns in the field and significantly reduce onsite assembly time. Its systems offer greater safety and reliability than ordinary designs and reduce the total cost of perforating operations.

SWM's most innovative product is its self-orienting perforation system. The system uses a fully internal rotating mechanism as a significant improvement upon conventional weight bar systems. In October 2020, SWM completed lab testing of their second generation self-orienting system, which successfully underwent operator field trials at the beginning of 2021.

In addition to perforation gun systems, SWM offers switches, test boxes, and other perforating accessories that ensure the highest reliability and greatest control in the field.
