LACT Meter

Definition - What does LACT Meter mean?

A LACT Meter is an important measuring instrument used during the custody transfer of crude oil and natural gas. It measures the amount (net volume) and quality of hydrocarbons transferred between two parties in business. The volume measured by LACT meter ranges between 100 to 1000 Barrels of Oil per Day (BOPD). LACT Meter is also known as Lease Automatic Custody Transfer Meter.

Petropedia explains LACT Meter

A LACT meter is primarily installed in pipelines that carry oil or natural gas from lease locations where production takes place. These locations are generally unattended by engineers on a regular basis and thus, such instruments are needed so that they can communicate the measurement as well as the quality of the hydrocarbon produce. Therefore, these meters are considered as smart meters that can provide automatic measurement of net volume transferred into the pipelines. They can even estimate the quality of hydrocarbons, i.e., they can provide information on the API gravity of crude oil as well as British Thermal Units in case of natural gas. In order to design a LACT unit, the following properties should be known:

  • Operating Pressure of a well
  • Rate of flow of hydrocarbons
  • Temperature
  • Gravity
