Water Well Drilling Cost Per Foot in Oklahoma (2026): $25-$55/ft

When Oklahoma drillers quote you a price, it almost always comes down to a per-foot rate. Understanding what that rate includes — and why it ranges from $25 to $55 per foot — is the single most important thing you can do before signing a contract. This guide breaks down per-foot drilling costs across Oklahoma so you can evaluate quotes with confidence.

What’s Included in Oklahoma Per-Foot Pricing

Most Oklahoma drillers include the following in their quoted per-foot rate:

• Drilling labor and equipment mobilization — getting the rig to your property and the actual drilling operation
• Drill bit wear and fuel — consumables used during boring
• Basic borehole logging — recording depth, geology, and water-bearing zones
• Drilling fluid — mud rotary or air rotary medium for flushing cuttings

What’s Typically NOT Included

These items are typically quoted separately:

• Well casing — PVC or steel pipe lining the borehole ($8–$25 per foot)
• Well screen — slotted section at the water-bearing zone ($10–$20 per foot)
• Grout and seal — cement seal preventing surface contamination ($3–$8 per foot)
• Pump and pressure system — submersible pump, pressure tank, wiring ($2,500–$6,000)
• Electrical hookup — wiring from well to home electrical panel ($1,000–$3,000)
• Water testing — bacteria, mineral, and chemical analysis ($150–$500)
• Permit fees — varies in Oklahoma (Oklahoma Water Resources Board (OWRB); all groundwater use requires a permit or must qualify for domestic exemption (under 5 acre-feet per year)) — typically $50–$500

Always ask for an itemized quote to see exactly what your per-foot rate covers.

Casing Cost Per Foot in Oklahoma

Casing is one of the biggest cost variables beyond the drilling itself:

Casing Type	Cost Per Foot	Best For	Lifespan
Schedule 40 PVC (4”)	$8–$12	Shallow wells, sandy/sedimentary formations	30–50 years
Schedule 80 PVC (4”)	$10–$16	Standard residential, moderate depths	40–60 years
Steel (4”)	$15–$25	Deep wells, hard rock formations	50+ years
Steel (6”)	$20–$35	High-flow residential, light irrigation	50+ years

In areas of Oklahoma with hard bedrock or deeper wells (typically the upper end of the 50–500 ft range), steel casing is often required because PVC can crack at depth. In sandy/sedimentary regions and shallower wells, PVC handles the load.

How Depth Affects Per-Foot Rates in Oklahoma

Per-foot rates often increase with depth — even within Oklahoma:

0–200 feet: The most straightforward drilling. Standard rigs handle these depths easily; formations are usually softer. Rates stay at the $25–$38 range.

200–400 feet: Rates typically increase $5–$10 per foot above the base rate. Harder formations may be encountered, drilling takes longer per foot, more casing is required.

400–600 feet: Specialized equipment may be needed. Drill bit changes are more frequent and the risk of problematic formations increases. Add $10–$20 per foot above base rate.

600+ feet: Heavy-duty rigs, steel casing, and significantly more time. Rates can reach the upper end of Oklahoma’s range ($55/ft) or beyond. Oklahoma’s deepest wells are typically in the 400–500+ ft range.

Many Oklahoma drillers quote a base per-foot rate for the first 200–300 feet, then a higher rate for additional depth. Make sure your quote specifies the rate structure for different depth tiers.

Why Per-Foot Costs Vary in Oklahoma

Oklahoma’s diverse geology includes Permian red sandstone and gypsum in the west, Arbuckle Group carbonates in the south-central region, and thin alluvial deposits along major river valleys. The Panhandle overlies the Ogallala Formation, while eastern Oklahoma has fractured Ozark-type carbonates and shale.

The geology summarized above is the primary driver of per-foot cost variation within Oklahoma. Areas with softer sedimentary formations drill faster and cheaper. Areas with limestone, granite, or volcanic rock require slower, more expensive methods. Oklahoma’s primary aquifer — the Ogallala (High Plains) Aquifer / Arbuckle-Simpson Aquifer / Garber-Wellington Aquifer / Alluvial and Terrace Aquifers — sits at 30-150 feet for alluvial aquifers; 100-500 feet for bedrock aquifers; 50-300 feet in the Panhandle, which directly affects how deep your well must go.

Total Well Cost Estimates in Oklahoma

Here’s what Oklahoma property owners actually pay when you combine per-foot drilling, casing, pump, and all other costs:

Well Depth	Drilling Only	Complete System (with pump, casing, electrical)
50 ft (shallow)	$1,250–$2,750	$3,750–$7,750
185 ft (typical)	$4,625–$10,175	$7,125–$15,175
500 ft (deeper)	$12,500–$27,500	$15,000–$32,500
500 ft (deepest typical)	$12,500–$27,500	$15,000–$32,500

How to Compare Per-Foot Quotes

When you receive quotes from multiple Oklahoma drillers:

1. Confirm what’s included. A $40/ft quote that includes casing is cheaper than a $30/ft quote where casing is extra.
2. Ask about depth tiers. Will the rate increase after 200 or 300 feet?
3. Get a not-to-exceed estimate. Good drillers cap the total cost based on expected depth in your area.
4. Check for mobilization fees. Some drillers charge $500–$2,000 to move the rig, especially for rural locations.
5. Verify licensing. Oklahoma requires well drillers to be licensed by the OWRB.

We recommend getting at least three quotes. Request free quotes from licensed Oklahoma drillers to compare pricing in your area.

When to Drill in Oklahoma

Year-round in most areas; ice storms in winter can delay access in the northeast

Driller schedules typically fill 4–8 weeks in advance, especially in peak drilling season. Off-season drilling (where weather allows) sometimes captures 5–15% labor savings.

Frequently Asked Questions

How much does it cost to drill a water well per foot in Oklahoma?

Oklahoma well drilling costs $25–$55 per foot in 2026, with $38 per foot as the average. Total cost depends on depth — a typical 185-foot well costs $4,625–$10,175 for drilling alone, plus $2,500–$5,000 for pump and connection.

Why is well drilling cost per foot different across Oklahoma?

Oklahoma’s geology varies regionally — softer sedimentary formations drill faster and cheaper than hard limestone, granite, or volcanic bedrock. Wells targeting deeper aquifers also cost more per foot because of additional drill bit wear, slower progress, and the need for steel rather than PVC casing.

Does the per-foot rate include the well casing?

Usually not. Most Oklahoma drillers quote drilling and casing separately. PVC casing adds $8–$16 per foot; steel casing adds $15–$35 per foot. Always ask for an itemized breakdown so you know exactly what the per-foot rate covers.

How deep do you have to drill for water in Oklahoma?

In Oklahoma, residential well depths typically range from 50 to 500 feet, with 185 feet being the average. Your specific depth depends on local geology, target aquifer, and how productive nearby wells have been. The Ogallala (High Plains) Aquifer / Arbuckle-Simpson Aquifer / Garber-Wellington Aquifer / Alluvial and Terrace Aquifers is Oklahoma’s primary residential aquifer, sitting at 30-150 feet for alluvial aquifers; 100-500 feet for bedrock aquifers; 50-300 feet in the Panhandle.

Is it cheaper to drill a shallow well in Oklahoma?

Yes — both the per-foot rate and total cost are lower for shallow wells. A 50-foot well costs $1,250–$2,750 for drilling, while a 500-foot well runs $12,500–$27,500. However, you can’t choose your well depth — it depends on where the productive aquifers are beneath your property.

Do Oklahoma well drillers charge a flat rate or per-foot rate?

Most Oklahoma residential well drillers quote per-foot rates, though some offer flat-rate packages where well depth is predictable. Per-foot pricing is more common because depth can vary even between neighboring properties. Some drillers quote a base rate for the first 200–300 feet and a higher rate for additional depth.

How can I get the best per-foot rate on well drilling in Oklahoma?

Get at least three quotes from licensed drillers, drill during the slower season (year-round in most areas is peak; outside that window can save 5–15%), and choose a property access point that minimizes mobilization costs. Request free quotes here to compare rates from drillers in your area.
