EFM data is very important to operating companies because it is the basis for invoicing the services provided to their clients. Such data is known as Electronic Flow Measurement (EFM). While SCADA systems gather field data in real time either by exception or periodically every few seconds or minutes specialized measuring systems on the field are sampling the same data (pressure, temp, flow), multiple times per second, and that data is actually the one required to perform volumetric calculations. In a pipeline or gathering system, the data acquired by SCADA may also include flow/volume measurement data from the flow computers providing real-time measurement as the fluids are injected into the system and extracted from it.
It is also designed to allow the controllers to send commands to the field to execute some actions like opening and closing valves, starting and stopping pumps and many other control routines.
in response to the demand for a more comprehensive solution for managing volumetric metering systems independent from SCADA.Ī typical SCADA system (Supervisory Control and Data Acquisition) is designed to acquire real-time or near real-time process data from the field and display it in some form of HMI to controllers in a control room. SMADA is a new concept, or rather a twist on the traditional SCADA concept, introduced by Tory Technologies, Inc. In this article, we explain what a SMADA system is in the context of the Oil & Gas industry.
