Abstract
A tubing is anchored in a boiler casing positioned in a borehole that extends into a magma reservoir.

A geothermal system, comprising:
- a borehole extending from a surface into an underground magma reservoir;
- and
- a boiler casing positioned within the borehole and extending into the magma reservoir, wherein the boiler casing comprises a tubing anchor receptacle, the tubing anchor receptacle comprising:
- an outer body comprising an opening passing therethrough;
- a top receptacle formed in the outer body;
- and
- a grooved receptacle coupled to the top receptacle, wherein the grooved receptacle comprises:
- a helical groove sized and shaped to receive a notch of a tubing anchor configured to be coupled to the tubing anchor receptacle;
- and
- a vertical groove coupled to the helical groove and configured to receive the notch of the tubing anchor after the notch traverses the helical groove and to secure the notch in place.
