Abstract

Geothermal wells frequently form deposits of geothermal scale that can detrimentally affect subterranean operations. These deposits can be very difficult to remove from a surface. Conventional procedures for addressing geothermal scale often provide inadequate scale removal, in addition to creating a number of other issues. Methods for removing geothermal scale from a wellbore can comprise: introducing a descaling agent comprising an N-(phosphonoalkyl)iminodiacetic acid or any salt thereof into a wellbore of a geothermal well having geothermal scale present therein; contacting the geothermal scale with the descaling agent; and removing at least a portion of the geothermal scale from the geothermal well using the descaling agent.
