Abstract
In accordance with an illustrative embodiment of the present invention, an irrigation, commercial or municipal utility district high flow capacity water well is completed in a manner such that water is produced from a substantially horizontal lower portion of the well bore that is located in the lower 20% of the water saturated thickness of the aquifer.
Claims6
A method of completing a high flow rate water well for irrigation, commercial or municipal utility district use, comprising the steps of:
- drilling a vertical portion of the well bore into an aquifer and to approximately the air-water interface level thereon;
- forming the next portion of the well bore in said aquifer on a curve such that its lower end extends substantially horizontal;
- extending an outer portion of the well bore substantially horizontally along said aquifer a predetermined distance that is a function of a selected flow rate and the water saturated thickness of the aquifer;
- casing the well bore in a manner such that said outer portion is provided with water entry ports substantially throughout its length;
- and installing a pump at a level below said air-water interface by which the water entering said ports can be produced to the surface.
A method of completing a water well that extends into an aquifer having a water saturated thickness below an air-water interface, comprising the steps of:
- determining the flow rate at which the well will produce a needed amount of water for a selected purpose;
- from said flow rate and said saturated thickness, determining the length of a substantially horizontal portion of a well bore that will provide said flow rate;
- drilling and casing a first portion of said well bore that extends from the surface vertically downward to at least the top of said aquifer;
- hydraulically jetting in and casing a second portion of said well bore that curves through the aquifer from the bottom end of said first portion to substantially the horizontal;
- and hydraulically jetting in and casing a third section of said well bore which extends substantially horizontally into the aquifer for a distance substantially equal to said determined length, said third section having water entry ports along substantially the entire length thereof.
