Leveraging skill-sets tailored to oil and gas infrastructure management, Macmichael Nwaiwu designs and implements projects to benefit DTE Energy’s gas transmission pipeline in the Detroit area. As lead engineer of transmission integrity management, Macmichael Nwaiwu carries out his responsibilities with the aid of a team comprising four other engineers and several data analysts.
Natural gas has no smell or taste, and is invisible to the naked eye. People can detect natural gas odor only because mercaptan, a chemical humans experience as a foul smell, is added for safety purposes.
The chemical composition of natural gas is dominated by methane, which comprises roughly 90 percent of it. The remaining 10 percent or so is taken up by traces of carbon dioxide, nitrogen, ethane, and other gases. Natural gas originates underground in deposits of hydrocarbons. One theory goes that the deposits formed as a result of prehistoric sea life that ultimately created an energy-rich sediment.
In any event, it’s from these deposits that extraction firms source raw natural gas, which is distributed throughout the United States via millions of miles of pipeline.
