Oklahoma well drilling cost

Cost to Drill a Well in Oklahoma

Water wells in Oklahoma average about 139 feet deep across the 243,801 records in our database. At typical U.S. drilling rates, that puts the drilling and casing at roughly $3,700 to $5,600, before the pump, tank, treatment, and permits that complete a working system. Here is how the numbers break down, and the real Oklahoma data behind them.

Typical U.S. well drilling rates by depth

These are national average residential rates for the drilling and casing, not Oklahoma-specific prices. Rates fall into depth bands, with a setup (mobilization) fee on top. Use them as a yardstick, then get local quotes.

Well depth	Drilling + casing (per ft)	Setup fee
Up to 100 ft	$28 - $42	$400 - $600
101-300 ft	$24 - $36	$400 - $600
301-600 ft	$25 - $30	$750 - $800
601 ft and deeper	$21	$1,000

National residential rate model, drilling and casing only. Higher per-foot rates apply to larger casing and hard-rock drilling. Pump, pressure tank, treatment, and permits are separate (see below).

What Oklahoma well records actually show

Cost follows depth, so the most useful Oklahoma number we have is the real one: our database holds 243,801 water-well records across Oklahoma, with completed wells averaging about 139 feet deep. The typical static water level - how far down the water table sits - runs about 85 feet across 229,167 recorded readings. These are real construction records you can review before you hire.

What that means for a typical Oklahoma well

Illustrative drilling + casing at 139 ft

$3,700 - $5,600

This applies the national residential rate ($24 to $36 per foot at this depth) to Oklahoma's real average well depth of 139 feet. It is an illustration built from a national rate card and Oklahoma's recorded average depth - not a quote, and not a price observed in Oklahoma. Your actual cost depends on your site's depth, geology, and casing, plus the pump, tank, treatment, and permits covered below.

One more thing quotes can't promise: depth. Nobody knows exactly how deep the water is until the drill finds it, so drillers quote a per-foot rate against an estimated depth - and if your well has to go deeper to reach a reliable aquifer, the extra footage bills at that same rate. That is normal practice, not a sign of a dishonest driller. Budget a 15-25% depth contingency above any estimate, and plan for the deeper half of your local range rather than the shallowest case.

Beyond the hole: the complete water system

The drilled hole and casing are only part of the bill. A working well also needs a pump and pressure tank, wiring and a pitless adapter, a sanitary cap and grouting, water testing, and often treatment for hardness, iron, or bacteria. Add it up and a complete private well system commonly runs $8,000-$25,000 for Oklahoma, based on our state cost research, versus $5,000-$15,000 nationwide. The low end is a shallow well with simple equipment; the high end is a deep well with treatment and difficult access. A typical Oklahoma project takes 2-4 weeks from planning to usable water.

What drives the cost of a well in Oklahoma

Depth
The biggest lever. Oklahoma wells average about 139 feet, but deeper aquifers mean more feet at the per-foot rate.
Geology and casing
Hard rock drills slower and can push per-foot rates toward the high end. Loose or caving formations need more casing, which adds material cost.
Water table and yield
The water table around Oklahoma sits near 85 feet in our records, but wells are drilled well past it to reach a dependable, year-round supply.
Pump, tank, and treatment
The pump, pressure tank, and any treatment for hardness, iron, or bacteria are a large share of a complete system - often several thousand dollars.
Permits and testing
Oklahoma: Not required for domestic wells. Permit, inspection, and water-test fees are usually modest but affect the timeline.
Site access
A rig needs room to work. Tight lots, long driveways, steep grade, or remote sites raise mobilization and labor.

Well drilling cost FAQ for Oklahoma

There is no single Oklahoma price - cost tracks depth, geology, and casing. As a starting point, water wells in Oklahoma average about 139 feet deep in our records, and at typical U.S. residential drilling rates that works out to roughly $3,700 to $5,600 for the drilling and casing alone. A complete water system (pump, pressure tank, treatment, permits) commonly runs $5,000-$15,000 nationwide. Get written quotes from at least two licensed Oklahoma drillers for a real number.

Typical U.S. residential rates run about $21 to $42 per foot for drilling and casing, with the lower end on shallow, small-casing wells and the higher end on shallow large-casing or hard-rock work. Most drillers also charge a setup or mobilization fee of a few hundred dollars. These are national averages, not Oklahoma-specific prices - your driller's rate depends on local rock and rig.

Across the 243,801 Oklahoma well records in DrillerDB, completed wells average about 139 feet deep. Depth is the single biggest cost lever: because drilling is priced largely per foot, a well twice as deep costs roughly twice as much to drill. Your site's actual depth depends on where the local aquifer sits, so a local driller reading nearby records is the best guide.

Permitting in Oklahoma: Not required for domestic wells (OAC 785:35-7-1). Permit and inspection fees are usually a small part of the total, but they affect the timeline. A licensed Oklahoma contractor typically pulls the permit and folds it into the quote.

The drilled hole and casing are only part of it. A working system also needs a pump and pressure tank, wiring and a pitless adapter, a well cap and grouting, water testing, and often treatment for hardness, iron, or bacteria. Those add several thousand dollars on top of the drilling, which is why a complete private well system commonly runs $5,000-$15,000.
