What is the Joule-Thomson Effect?
The Joule-Thomson Effect, also referred to as the JT effect, is an important concept that can negatively affect oil and gas production if not accounted for.
Discovered by British physicists in the 19th century, this principle states that when the pressure of a gas changes, its temperature also changes.
In natural gas production, this means that when you reduce gas pressure across a control valve or pressure reducing regulator, you also reduce its temperature.
