Reverse Circulation Drilling FAQs

  • What is reverse circulation drilling (RC drilling)?

    • Reverse circulation drilling uses drill rods with inner tubes inside to allow the sample/cuttings to return to the surface through the inner tube. The sample is produced by driving a pneumatically operated drill hammer and drill bit that is attached to the drill rods through the rock. This chipped sample then travels from the bottom of the hole, up through the inner tubes and out through a sampling system where it is collected for analysis.

  • What type of drill is used for reverse circulation drilling?

    • There are many types of RC drills with technology and innovation always improving. Generally, RC drill rigs are larger than other forms as they are fitted with compressors, engines, pumps and drill rods.

  • What are the key benefits of reverse circulation drilling?

    • RC is generally cheaper than diamond and is a faster form of drilling which allows quicker return on the sample results. The equipment can be packed up and moved easily while achieving good depths of up to 500 metres.
