Core Drilling Rig Price Guide: Wireline, Hydraulic and Portable
July 30, 2026 Β· 10 min read Β· Updated October 31, 2026
A core rig differs from a water well rig because it is responsible for core quality. Price is not only about depth. It includes the coring method, tooling precision, hydraulic control and deviation control. Here is how the number is built.
1. Start with the coring method
| Method | Feature | Use |
|---|---|---|
| Conventional coring | Simpler equipment, more tripping | Shallow holes, limited core |
| Wireline coring | Retrieve core without tripping rods | Deep, continuous exploration |
| Fully hydraulic top drive | Precise control, more automation | Difficult ground, high specification |
| Portable | Modular, can be dismantled | Mountains, poor access, frequent moves |
Wireline and fully hydraulic rigs cost more, but on deep continuous programmes the saved tripping time and better recovery can offset part of the difference.
2. Six cost components
- Host and mast: depth raises structural strength and mast height.
- Head: torque, speed range and through-bore decide tooling capability.
- Hydraulics: pump, valve, motor and cooler are the main cost of a hydraulic rig.
- Winch and wireline system: required for depth and wireline coring.
- Tooling: rods, core barrel, core lifter and diamond bits.
- Chassis and transport: crawler, trailer or modular.
3. How depth and diameter change price
A core rig depth rating usually refers to a specific hole diameter and rod string. The same rig may go deeper at a smaller diameter and less deep at a larger one. Ask:
- What diameter and rod size does the rated depth use?
- Is wireline tooling included?
- What are the maximum pull and rope capacity?
- What is the realistic penetration rate in hard rock?
4. Fully hydraulic or mechanical top drive
Fully hydraulic machines offer precise control and automation for difficult ground and high-specification work, but hydraulic components and maintenance cost more. Mechanical top drive is simpler and easier to maintain, suitable for routine core drilling. Julong JDL-280 and JDL-350 are mechanical top-drive; JY-600, JY-800 and JY-1000 are fully hydraulic core; JY600Q is portable. Choose by project requirement, not by which sounds more advanced.
5. Is portable worth it
Portable wins where the site cannot be reached by vehicle. The trade-off is modular design, assembly time and module weight limits. If access is good, a crawler or trailer rig is more productive. If vehicles cannot get in, portable is the only practical option.
6. What the quote must state
| Item | Require |
|---|---|
| Depth capability | Diameter, rod size and ground |
| Coring method | Conventional, wireline, winch included |
| Tooling list | Rods, core barrel, lifters, bits, quantities |
| Hydraulics | Main pump, valve and motor brands and specs |
| Chassis | Crawler, trailer, modular, shipping dimensions |
| Service | Commissioning, training, warranty, spares |
7. Do not ignore recovery
The value of a core rig is core recovery and sample representativeness, not metres per hour alone. Low recovery or disturbed core affects assays and resource estimates. At a demonstration, inspect core condition, bit wear and lifter reliability, not only the penetration rate.
Frequently asked questions
Why does a core rig cost more than a water well rig?
A core rig is built for recovery: precise tooling, winch or wireline system and finer hydraulic control. A water well rig prioritises diameter, cuttings removal and yield. Different duties, so prices are not directly comparable.
Is wireline coring worth the extra cost?
For deep holes, continuous coring and high tripping time, usually yes. For shallow holes with limited coring, conventional coring may be more economical.
Are portable core rigs very slow?
Assembly and module limits add handling time, but where vehicles cannot reach the site, portable is the only option. On good access, crawler or trailer rigs are more productive.
