The RC Sampling Risks We Solve
Reverse-circulation exploration must deliver a reliable sample stream while drilling through changing formations. Airflow, sealing, bit condition and sample handling have to work as one system.
01
Sample Contamination
Control cross-flow, worn interfaces and sample-path leakage that can compromise geological confidence.
02
Poor or Inconsistent Recovery
Match face design, airflow and operating parameters to maintain a representative chip sample.
03
Wet & Variable Formations
Adapt the RC configuration when water, weathered zones or fractures interrupt dry sample return.
04
Remote-Site Downtime
Plan wear parts and compatible tooling before mobilization to protect the drilling schedule.
RC Exploration Drilling in the Field
From drilling and sample return to geological logging, every stage should protect sample identity and support faster field decisions.
SAMPLE-LED RC SYSTEM SELECTION
A Practical RC Configuration for Exploration Programs
HLDRILLS starts with the sample objective, expected geology and required hole depth. We then review the rig, compressor, drill string, RC hammer, bit and sample-return path as one connected system.
The target is dependable sample quality and drilling continuity—not maximum penetration at the expense of recovery or geological confidence.
Recommended Configuration Logic
Final specifications are confirmed after project-condition review.
- Objective: exploration, grade control, resource definition or geological confirmation
- Formation: weathering, fracture frequency, abrasiveness and groundwater
- Hole: diameter, depth, inclination and sample interval
- Air system: compressor capacity, annular velocity and sample return
- Tooling: RC hammer, bit, inner tube, connections and wear plan
GEOLOGICAL EXPLORATION
From Exploration Target to Representative Sample
A four-step workflow aligns the geology, RC system and field operating plan.
STEP 01
Program Review
Collect target geology, sample requirements, hole geometry, rig, compressor and site logistics.
STEP 02
RC System Matching
Match hammer and bit size, drill-string interface, airflow and sample-return components.
STEP 03
Trial & Parameter Setup
Confirm rotation, feed, pressure and sample handling on the first controlled holes.
STEP 04
Recovery & Wear Review
Track recovery, contamination and wear, then refine the configuration for the program.
