Fiscal Metering Skid for oil & gas industry

Posted on August 7, 2015 at 4:00 PM by Vienerg

This blog explains the basic concepts and techniques of Metering Skid necessary to design specify and manage oil and gas production facilities.

Metering Skid Plays a vital role in the precision measurement for both buying and selling of hydrocarbons . Every transaction made by the petroleum producers need to know the net volume of hydocarbons/ gases going into the pipeline/Ship/Truck . Many Petro chemical plants ,LPG, and oil & gas processors use fundamentally distinct systems for such measurements.
Metering Skid is a Custody transfer flow meter where the fiscal calculations are determined and it is used for Oil & Gas applications in the Truck loading facility, Jetty facility. Metering Skid comprises of fluid filtration, pressure regulation, metering section and flow control.

Lease Automatic Custody Transfer(LACT) :

A LACT unit is used for custody transfer of oil/gases .In large facilties, oil is typically sold through a LACT unit and this unit is designed to meet API Standards and other additional measuring standards as required by the purchaser. The LACT unit not only measure the net volume and quality of liquid hydrocarbons accurately, but must continuously monitor the BS&W(Basic Sediment and water) content .

The Crude oil first flows through a strainer and gas eliminator, thus protecting the pump & meter and also improving the measurement accuracy.
Depending on the application, metering skid has all kinds of custody transfer flow principles such as PD meters, turbine meters ,Orifice plates,coriolis meters, ultrasonic meters and other types of flow meters.

Liquid and Gas Metering Skid :

  • Fully Integrated Metering Skid

  • Instrumentation (Pressure, volume, etc.)

  • Valves and Pipes (Check valve, Prover loop valve, Back pressure Valve etc.)

  • Flow meters (PD meters, Turbine meters, coriollis mass meters, etc.)

  • Metering Houses with

  • Strainer/air eliminator

  • Pump

  • BS & W analyser

  • Sampler

  • Meter prover

  • Flow computers And Control panel

  • Truck Loading Facility
    For Loading bulk gas oil skid, the monitor protection system shall be fully integrated with pumps, loading arms , instrumentation, security control systems, meters, Batch controllers and Terminal automation system.
