Control the flow.
Dedicated to advancing the technologies that make geothermal a scalable foundation for clean baseload power and heating.
The completion sequence.
Two or more wells, drilled near-horizontal in close proximity.
Fractured with our patented sliding sleeves.
Flow actively regulated in every fracture.
The completion, rebuilt for heat.
Perf and plug was developed for Shale, where a well is stimulated once and then produced until it declines. An EGS reservoir is a waterflood and requires mechanical flow control. GTO Improves three things about the completion to keep the heat exchange volume productive for decades.
Reduced pressure loss leads to lower parasitic losses, delivering more power to the grid.
Slickwater fracs cause significant pressure loss, resulting in significant parasitic losses and less power to the grid.
Minimal reduction of original casing diameter. Cemented for zonal isolation. No extreme-temperature packers. No inner conformance string.
Inner conformance string and extreme temperature packer at every stage = significant parasitic losses and completion costs.
3 sleeve positions : fully open, regulated, or shut off. The reservoir stays tunable as conditions change, extending asset life.
Not available without inner conformance string. Performance depends on the game of chance of the fracture conductivity.
Measured against the incumbents.
Parasitic losses from wellbore friction and fracture flow determine how much of a well pair's gross thermal output reaches the grid. By increasing fracture conductivity and regulating each fracture individually, GTO's system delivers an increase of 1.2 MW net from a 10 MW gross well pair. By controlling the thermal decline the well life expectancy can increase from 9 to 19 years!
