1. A method for completing a wellbore, the method comprising:
drilling a borehole from a surface, towards a magma chamber, and into the magma chamber;
supplying a drilling fluid to an interface between a drill bit and a terminal end of the borehole, wherein the drilling fluid lifts cuttings out of the borehole, and wherein the drilling fluid quenches magma to form a solid phase material that can be cut by the drill bit;
terminating the drilling in response to the borehole achieving a predetermined depth;
supplying a thermodynamic fluid into the borehole to maintain the solid phase material of the borehole while completing the wellbore, wherein the thermodynamic fluid is in contact with sidewalls of the borehole;
casing the borehole from the surface to the terminal end of the borehole located in the magma chamber; and
sealing a terminal end of the casing with an end cap that prevents the thermodynamic fluid from contacting the solid phase material.
