International School of Hydrocarbon Measurement

ISHM is believed to be the oldest petroleum industry school in the world devoted to fluid measurement and control.

Since its inception, except for one year during the depression of the “thirties”, one year during World War II and the recent cancelation of the 2020 and 2021 schools due to the Covid-19 pandemic, the School has met annually in the spring. Until 1972, the content of the Short Course was confined to Natural Gas Measurement, Flow Rate and Pressure Control.

As the supply and demand problems in the United States worsened and imports of petroleum liquids increased, it became apparent that improved measurement practices were of paramount importance. The decision was made to change the name to the International School of Hydrocarbon Measurement (ISHM), and to expand the curriculum to include measurement and handling of all petroleum liquids, ranging from liquefied natural gas (LNG) to tar sand slurries.
