WAG^TM Water Alternate Gas Injection Controller

Enhanced oil recovery and extending the useful producing life of existing oil fields is a hot topic at the current oil prices. One of the methods to boost oil production in existing fields is to inject water or gas (carbon dioxide) into injection wells. This is generally considered to be a tertiary recovery method and is used after normal formation pressure and secondary techniques like gas reinjection and water floods have been used.

Water injection sweeps the oil from the injection sites to the producing wells. Carbon dioxide alters the viscosity of the oil for easier oil movement. The combination of oil, water, carbon dioxide, and natural gas is pumped out of the formation by the producing wells, and separated out into its components for further injection processing, sale, or transport.

Our injection controller allows either pressure control with flow rate limiting option or flow rate control with a pressure limiting option to safely inject water alternating with carbon dioxide into the formation to facilitate this process. Pressure fall off, step rate, and step pressure tests assist the production engineers in optimizing the injection characteristics for a particular formation.

 Water Injection Controllers

If you need to control the injection or re-injection of water into a formation, our WIC-II^TM injection controllers provide complete monitoring and control of the process. They have the same pressure control with flow rate overrides and flow rate control with pressure overrides as our popular WAG controllers but are configured strictly for water operation to simplify the setup process.

Finally, if you just need to monitor the water volume and pressure being injected, use our WFM^TM controller.

A version of our WAG software has also been ported to the SCADAPack hardware platform for customers who have experience with that hardware and would like to have a smaller number of hardware platforms to support in their fields.

We have also ported the software to the 350 model. This package also supports a bluetooth operator interface.
