Desert wells generate only in desert biomes. They have a 1⁄1000[JE only] or 1⁄500[BE only] chance to be generated in any desert chunk, which makes them a rare sight. It is possible for a well to generate around a cactus. The well structure will still generate with the "Generate Structures" option disabled.
In Bedrock Edition, desert wells have a chance to generate in a cluster between 16 blocks.
Desert well generation is capped at the coordinate Y-128. If desert terrain is extended higher than Y-128 (via add-on), no desert well will be generated.
