Surface Casing Vent Pressure Tests
SCADACore Live Surface Casing Vent Pressure Test can function for months saving time and ensuring consistency.
Surface Casing Vent Pressure Tests
The Surface Casing Vent Pressure Test is generally lasts 1 to 2 weeks and is repeated several times to ensure accuracy. Using SCADACore Live, the tests can be performed without having to visit the site. After the initial install the Surface Casing Vent Pressure Test can function for months, saving time and ensuring consistency for the duration of the test.
As wells age, the well casing deteriorates, and allowing the flow of gas and liquids through the walls of the casing. This has significant impact on the safety of the gas well as well as environmental effects caused by leaking liquids into the groundwater.
Surface Casing Vent Pressure Tests / SCVF help to determine the integrity of the well casing and if any additional down-hole maintenance needs to be performed.
A typical test will start with in the Flow State that will produce a base-line reading of the typical pressure and flow of the well. Following a flow reading the tester will remotely change modes putting the test unit into the Build-Up State which. The Build-Up state closes the flow valve allowing pressure to build up inside the well. Pressure will build up quickly at first and slowly level off. Following the Build-Up mode the tester will remotely change modes again to the Vent state, which bleeds off pressure from the casing in preparation to reset the test.
With the casing pressure removed the tester can return the test unit into a flow state to, once again, retrieve a base-line reading and begin the test over again.
SCADACore SCVP Monitoring Features
The system is fully-featured with powerful graphing features, voice / SMS / email alarm callouts, and data import and export support, all packaged in an all-inclusive package.
Overview
The SCADACore Live Dashboard summary page allows users to quicly view the status of the current and archived Surface Casing Vent Pressure Tests. The easy to navigate summary grid gives users a view of the current conditions of the active Tests.
Graphs will display the latest data in graph form.
If there are multiple active units a Map view can give a broader picture of the tests.
The live data view of the Surface Casing Vent Pressure Test gives the user a real-time view of the current state of operations for the test.
Users can identify the well by Location, UWI, and License Number.
The Live readings shows both the mode of operation as well as the latest readings. To update the readings in real-time simply click the “Poll Device” button to retrieve the latest information from the device.
The Chart is completely interactive and can be used to compare previous cycles
The graphic at the bottom helps users understand the current state by showing how the gas is flowing in the current operation.
With SCADACore Live Testers and Producers can run multiple test cycles without the need to visit site. With high pressure safeguards in place there is no risk of leak or damage to the equipment.
Vent Mode
The vent state opens the vent valve to relieve pressure in the well. The Flow Valve remains closed.
Switching to the Vent State will clear all accumulated numbers in the PD Meter and prepare the tester to begin another test.
Build-Up Mode
In the Build-Up State the Vent Valve remains Closed but the Flow Valve is also closed. This prevents gas from flowing out to the pipeline. Pressure is built-up downhole in the well.
Flow Mode
During the Flow-State the Vent Valve is close flowing the gas through the pressure and PD meter to obtain both pressure and flow readings.
The Historical summary combines the States of the Surface Casing Vent Pressure Test in one easy to read chart. The chart allows the tester to quickly understand the behaviour of the well through the states of the test.
