The Fluid Management System (FMS)

The fluid management system (FMS) is a physical system configuration consisting of tanks, pumps, control systems, injection systems, chemicals delivery and others. The purpose of FMS is to deliver liquid chemicals to a targeted objective zone to modify fluids chemistry such as acid neutralization, inhibition of calcite, and inhibition of silica scale. The chemicals delivery of the FMS can be at subsurface (reservoir depth). This is usually done in acid neutralization to mitigate corrosion problems at the reservoir and with calcite inhibition to keep the fluid minerals from precipitating. The surface injection injection can also be done with calcite inhibition (geothermal pipeline), for acid neutralization at wellhead and silica scaling at the brine line. The FMS can be a simple or complicated system and be designed and developed according to the geothermal client’s requirements and objectives.

FMS for Acid Neutralization consists of chemical storage tanks, mixing tanks for chemical dilution and holding tanks of chemicals for injection. This set-up will have tanks for the transfer of chemical and a high-pressure pump to deliver the chemicals. Delivery of chemicals to a target reservoir depth will be through a capillary tubing, an injection system that is set up at the wellhead, and a set-up of weights that will roll down the capillary tubing to the target depth.   

FMS for Calcite Inhibition is almost similar to FMS for acid neutralization. With the minor difference in the tank configurations.

FMS for Silica Scaling Inhibition is a simple set-up for chemical delivery at the surface geothermal pipeline. The set-up will have a simplified set-up of tank configuration and low-pressure injection pumps

Wilclad can design, manufacture, procure, and install an FMS package suitable for geothermal client requirements and purposes.
