About SWM Technologies
SWM began in 1980 when Sid Mauldin started his own company called “Specialty Welding.” Starting with a single customer, a pickup truck, and a small shop building, Sid focused his new company on repairing perforating guns. Sid’s high-quality repair work and customer-first approach soon got the attention and respect of the wireline industry and was the impetus behind Specialty Welding’s growth. After years of helping Sid after hours and on weekends, Dawna Mauldin officially joined her husband full-time in 1999.
Early in the 2000s, the company began investing in machining capabilities and manufacturing new perforating guns. In 2006, the company moved to a larger facility to house its expanding manufacturing capability, which now measures in excess of 100,000 square feet.
In 2016, Specialty Welding changed its name to “SWM International,” continuing to serve its customers by providing high-quality, reliable perforating guns.
Starting in 2022, the company grew the scope of its product and service offerings through the acquisition of Wireline Supply, a full-service wireline and oilfield products distributor in Midland, Texas. Following the acquisition of Wireline Supply, SWM acquired AdvancedPerf, a leading supplier of charges.
SWM Technologies Today
After having successfully assimilated Wireline Supply and AdvancedPerf, SWM is now able to offer its customers the full range of perforating guns, charges, accessories, and related services under the new company name, SWM Technologies. From its Pampa, Texas headquarters, today’s SWM serves the perforating needs of every major domestic producing area, operating as a cooperative, collaborative teammate for its wireline and E&P company customers.
Description of Services
- Perforating Gun Systems
Industry-Leading Perforating Gun Systems
SWM’s advanced perforating gun systems, and the technology behind those guns, underscore the company’s commitment to providing industry-leading gun designs and the best match of gun to the perforating application. As part of its commitment to the industry, SWM encourages customer feedback. This part of SWM’s way of doing business is highlighted by the fact that customer requests have driven a number of the company’s innovations, leading to easier gun operation and optimal perforating outcomes.
In addition to producing high performance perforating guns, SWM can be counted on for industry-leading customer support. Our people in the field are true service reps, not salespeople, and their only job is to assist the customer and help in any way possible to ensure effective perforating outcomes. And if there are any issues, even if competitors’ products are involved, SWM service reps are ready to respond in a timely and helpful manner.
SWM now offers the industry’s leading self-orienting perforating system.

Tools and Supplies for Wireliners

The key to the success of this unique business is its emphasis on customer service. On many occasions, the company has gone the extra mile to help a customer out of a bind. For added convenience, some customers will buy all of their necessary supplies once a month, using a company purchase order instead of a credit card. Credit card purchases are accepted, as well. Wireline Supply can handle transactions either way, offering whatever works best for the customer.
Perforating Gun Loading
SWM’s gun loading operation is also located within the Wireline Supply facility. The company stores a large inventory of guns, charges, and detonators, all ready to be assembled into fully loaded packages.
