Methodology
Our approach to water well drilling in Shreveport begins with a comprehensive site evaluation, including review of existing well logs and geological maps. We conduct test drilling to determine aquifer properties such as transmissivity and storage coefficient. Drilling methods are selected based on subsurface conditions: for unconsolidated alluvium, we commonly employ mud rotary drilling; for deeper consolidated formations, air rotary or down-the-hole hammer methods are used. Well construction follows industry best practices: casing is set through unstable overburden, and a gravel pack is installed in the screened interval to minimize sand pumping. Development techniques, including surging and pumping, ensure maximum well efficiency. For detailed service information, visit our water well drilling page.
Reference Technical Parameters
| Parameter | Reference Value |
|---|---|
| Predominant Soil Type | Alluvial sands, silts, and clays (Red River deposits) |
| Typical Groundwater Level | 10–30 ft below grade |
| Bedrock Depth | Variable, 100–200 ft (Cretaceous marl and chalk) |
| Typical Well Yield | 50–500 gpm, depending on aquifer |
| N60 Range (SPT) | 4–30 blows/ft in sands; 2–15 in clays |
Local Considerations — Shreveport
Shreveport's location within the Red River Valley influences well drilling in five key ways: (1) Shallow groundwater in the floodplain requires careful sealing to prevent surface contamination; (2) Interbedded clay lenses can confine aquifers, creating artesian conditions that necessitate proper annulus seals; (3) Seismic hazard is low (peak ground acceleration <0.1g per ASCE 7-16), but wellheads should be anchored to prevent displacement; (4) Older residential areas may have wells with insufficient casing depth—our team often recommends deepening or replacement; (5) Industrial zones near the river require larger-diameter wells for process water. For projects requiring specialized expertise, our deep water wells service addresses high-yield aquifer development. Additionally, our water well drilling en Houston hub provides regional support for cross-border projects.

Frequently Asked Questions
What types of soil are common in Shreveport for well drilling?
Shreveport's subsurface consists primarily of alluvial sands, silts, and clays deposited by the Red River. These layers can vary rapidly over short distances, requiring careful site-specific evaluation to design an effective well screen and gravel pack.
Are there seismic considerations for water wells in Shreveport?
Shreveport is in a low seismic hazard zone per ASCE 7-16, with a maximum PGA of less than 0.1g. However, well construction should still follow standard anchoring practices to prevent damage from minor shaking.
What permits are required for drilling a well in Shreveport?
A permit from the Louisiana Department of Health is mandatory, along with compliance with local parish regulations. Our team handles all permitting and ensures the well meets state water quality and construction standards.
