Oil Dynamics installs submersible pump 900m deep for thermal resort

German pump specialist Oil Dynamics has been assigned to design, deliver and install a pumping system for Austria's largest thermal resort in Bad Loipersdorf.
The recently installed electric submersible pump (ESP) has also performed well during testing.
Once the pipeline is completed, the ESP will lift three to six litres per second of 60°C mineral-rich water from an installation depth of approximately 900m and deliver it uphill to the thermal baths.
Along with the pump, Oil Dynamics also supplied the complete surface equipment as a tailored, containerised solution.
In addition to the customer's control system, the ventilated and heated container includes a modern frequency converter ElektroMotion Technology ESP smartDRIVE and a fitting dry-type transformer.
While experienced field engineers installed the pumping system including the sub-surface sensor, HV-cable and wellhead penetrator, a OD software engineer configured the data interface to the resort’s control system.
Since the special production tubing was assembled using a relatively low torque, the pump had to be started up carefully - especially during the rotation test - to avoid loosening of any torqued connections.
