The AGE Riserless Pump System has been widely adopted throughout Australia as an alternative to the traditional riser column method of water transfer to surface for electric submersible pumps. The system works by sealing and supporting the pump in the casing with an inflatable packer. Utilising the bore casing itself as the riser, the frictional head losses incurred during transfer are greatly minimised due to the decreased velocity. Over time, this increase in operational efficiency leads to substantial power savings – in the order of tens, to hundreds of thousands of dollars per year.
The Riserless system is ideally suited to large, deep bores and offers even more advantages in new bores where the production casing and drilled hole diameter can often be reduced without affecting bore production rates. For ease of installation, all components are lowered into the bore using small diameter dual sealed AGE hanging pipe. The packer inflation tubes, motor cables and vent lines are secured to the hanging pipe at regular intervals to ensure they do not slump and cause issues. With the assembly at the required depth, the packer is inflated to support the pump and seal the casing. When the inflation tube and motor cables have been sealed, the bore is ready for pumping.
In addition to the reduced operational costs, the system also offers a number of other benefits over traditional submersible pump completion:
