Modern Drilling Equipment: Technologies 2025

Modern drilling technologies

The drilling industry has evolved significantly in recent years. Modern technologies allow faster, more precise and safer drilling.

1. Rotary Drilling

Principle: Rotary auger while drilling fluid is introduced.

Advantages:

• High forward speed
• Possibility to drill into rock
• Cooling and efficient transport of sand

Popular machines: Massenza MI8, Comacchio GEO 305, Beretta T41

2. Drilling with a bottom hammer (Down-the-Hole)

Principle: Pneumatic hammer mounted directly on the spade.

Advantages:

• Excellent for hard rock
• Concentrated impact energy
• Great depths possible

3. Percussion Drilling

Principle: The spade hits the bottom of the hole repeatedly.

Advantages:

• Simple and robust
• Good for soil and clay
• Reduced equipment cost

4. Electric logging (Electric Logging)

What is it: Geophysical method of investigating drilled layers.

Used for:

• Identification of aquifer layers
• Determination of water quality
• Optimizing filter position

Cost: 500-1,500 lei per drilling

5. GPS and GIS systems

Modern companies use:

• Precise GPS - For accurate location of wells
• GIS (Geographic Information Systems) - For aquifer mapping
• Drone - For terrain assessment

6. Tubing technologies

PVC pipes

• Corrosion resistant
• Lightweight and easy to handle
• Diameters: 125mm - 400mm
• Lifespan: 50+ years

Stainless steel tubes

• Superior mechanical resistance
• Ideal for great depths
• Higher cost

Johnson Filters

Stainless steel filters with precise slots:

• They prevent the entry of fine sand
• Allow maximum flow
• Long life span

7. Modern submersible pumps

Type	Max depth	Debit	Price
Grundfos SQ	150m	3-6 mc/h	2,500-4,000 lei
Grundfos SP	300m	5-20 mc/h	4,000-10,000 lei
Lowara SC	200m	3-15 mc/h	3,000-8,000 lei
Panels	100m	2-5 mc/h	1,500-3,000 lei

8. Intelligent monitoring systems

IoT technologies allow:

• Real-time throughput monitoring
• Automatic problem detection
• Remote control
• Phone/email alerts

Conclusion

Modern drilling technologies offer more efficient, faster and more durable solutions. When choosing a drilling company, ask what equipment they use - investment in technology usually translates into higher quality work.
