Keller Drilling & Well Service operates one Failing CF-15 rotary drilling rig which is competitive from 100 feet to 900 feet. We use drill bits from 7-7/8" to 12-1/4" and set casing from 4-1/2" to 8-5/8" diameter, PVC or steel.

We employ the slotted screen method by setting .020" factory cut PVC screens or .020" pipe base stainless steel screens, with gravel pack of fine gravel or coarse sand.

We seal the well from the surface with a bentonite seal or pumped cement.

We drill residential irrigation wells, house wells, commercial water supply wells, and Barnett Shale water supply wells.

WELL DESIGN

We conduct a thorough needs analysis for the customer prior to drilling the well.

We use the information from wells that we have drilled combined with well records from other drillers to best predict well results. Certain areas may deliver quite prolific wells, where others result in dry holes. Our goal is to reduce dry hole results, and sometimes we may recommend against the customer's desire to drill.

We attempt to determine the actual water demand by volume and pressure, and write our own specifications as to well size, depth, horsepower requirements. It is most important that well output is known prior to designing any irrigation system as an imbalance in well volume and system demand creates undesirable results.

We attempt to predict water chemistry of the well based upon local knowledge and sample analysis and seal off undesirable layers. Examples of undesirable water include certain layers contaminated with iron bacteria, and areas having a high total alkalinity. Both of these contaminants may result in staining or inadequate growth of landscape plants.

Keller Drilling & Well Service uses only quality products, such as slotted PVC casing from CertainTeed.
