Abstract
An industrial water well with heat resistant well casing. A thermally resistant well casing is provided within the well bore at a depth where a submersible pump is carried within the casing. The thermally resistant pipe will not be damaged by the heat generated by a failing or failed submersible pump, permitting the pump to be extracted and repaired/replaced before collapse of the casing.
Claims12
A water well, comprising:
- a well bore having a depth corresponding to a targeted subterranean water source;
- one or more well casing segments carried within the well bore to a depth corresponding to the targeted subterranean water source, wherein the one or more well casing segments includes at least one thermally protective well casing segment positioned within the well bore at a desired depth for a submersible pump configured to convey water from the subterranean water source to a top end of the bore.
A method of preparing a water well, comprising:
- determining a depth for positioning a submersible pump within a targeted subterranean water source;
- drilling a well bore extending into the targeted subterranean water source and inserting a well casing within the well bore;
- positioning a thermally protective well casing at the determined pump depth.
