Nitrogen Services, LLC are pipeline integrity specialists located in Midland, Texas. We have provided high-quality pipeline m ... aintenance and repair services throughout the United States for over 35 years. Nitrogen services offers onsite nitrogen generation, and pipeline pigging services. In 1984, our first portable nitrogen systems were developed under the name Oilfield Pipeline and Utility Services, Inc. (OPUS). The focus was primarily, but not exclusively, on pipeline technology, and was driven by the need to achieve greater cost and energy efficiencies over traditional supply by liquid transports. In November of 1994, the world’s first portable N2 generator was received and put in service in the oil field. The new technology fully met and exceeded all expectations. Cost reductions on the order of 20% to 50% were demonstrated versus liquid supply. In 2013, Nitrogen Services, LLC was formed to combine nitrogen, pipeline cleaning, hydrotesting, repair, and right of way services. Although originally focused on onsite nitrogen generation, we have expanded to include a more comprehensive suite of services including, liquid nitrogen, pipeline pigging, pressure testing, and repair work. read more
