Flow Metering Skid
A flow metering skid, also known as a Lease Automatic Custody Transfer (LACT) skid, are specialized metering and transfer systems used in the oil and gas industry to accurately measure and transfer custody of produced liquid hydrocarbons (oil or condensate) from the production site to the pipeline or transportation system.

The LACT skid typically consists of the following main components: ➣ Separators: These vessels separate the incoming multiphase fluid stream (oil, gas, and water) into individual phases. Separators may include a two-phase or three-phase separator, depending on the requirements. ➣ Metering runs: The metering runs consist of a section of piping designed to provide accurate measurement of the liquid hydrocarbons. They typically include:
• Meter prover: A calibrated section of piping used to verify the accuracy of the flow meter.
• Flow meter: A device that measures the volumetric flow rate of the liquid hydrocarbons, such as a turbine meter, Coriolis meter, or positive displacement meter.
• Strainers and filters: These components protect the flow meter from damage caused by solid particles or debris.
➣ Sample systems: Sample systems are used to obtain representative samples of the liquid hydrocarbons for quality analysis and custody transfer purposes.
➣ Instrumentation and control systems: The LACT skid is equipped with various instrumentation, such as pressure gauges, temperature sensors, and densitometers, as well as a control system to monitor and regulate the metering and custody transfer process.
➣ Valves and piping: Appropriate valves and piping are used to control the flow of fluids through the skid and facilitate maintenance and operations.
➣ Skid structure: The entire assembly is mounted on a skid or base, which provides a compact and transportable solution for easy installation and relocation.
LACT skids ensure that the volume and quality of the liquid hydrocarbons are accurately measured and recorded, facilitating the proper allocation of production, royalty payments, and compliance with regulatory requirements. They are designed to meet industry standards and specifications for custody transfer operations, ensuring reliable and consistent measurements.
These skids have been commonly used in various oil and gas production facilities, including onshore and offshore platforms, as well as in gathering and processing systems. They play a crucial role in the accurate accounting and transfer of produced hydrocarbons, enabling efficient and transparent transactions between producers, transporters, and buyers.
