Coring is an essential component of mineral exploration, but it can be a difficult task due to complex geological formations and harsh drilling environments. To overcome these challenges, a proper drilling mud system is used to make the drilling process more efficient and cost effective.
A proper drilling mud system should include proper lubrication. Lubricating and cooling down the drill bit minimizes wear and tear, which prolongs the bit’s lifespan and reduces downtime for replacing damaged bits. In addition, a good lubricant will assist core slide into the tube and make casing extraction at the end of the job more likely. If proper lubrication is not used, there is a good chance you will never be able to recover your casing!
Additionally, a proper drilling mud system should have the ability to stabilize the formation to prevent the hole from collapsing, at the same time it should protect the hole from unexpected clays that can swell around the drill string. Both of these scenarios can be time-consuming and expensive to resolve.
A proper drilling mud system should also have the viscosity and strength that will facilitate the removal of drill cuttings. This prevents the cuttings from settling and obstructing the coring operation. Proper cuttings removal is essential to maintain an accurate and undisturbed core sample.
It is also important to note, that an excess of trapped cuttings can easily cause unwanted hole deviation and will increase in hole torque. This high torque environment can lead to the premature wear of rods, the bit and put stress on your drilling rig, all of which can cost you time to solve reactively. So be proactive and make sure you have a proper drilling mud system!
Last, but not least is having the ability to recover as much core as possible! There is no point in drilling for core if you can’t recover any, am I right? Making sure you have the right drilling fluids for the right geology is important as some ground conditions can be more difficult than others, with sands and gravels being some of the toughest.
The Canadian Mud Company has made a proper drilling mud system, and we made it simple, real simple! The 4CORE Mud System simplifies the process by offering only four high-performance products that can handle most ground formations. The 4CORE Mud System is easy to mix and provides maximum lubrication, superior hole stabilization, powerful core recovery ability in sands and gravels, and the viscosity you need to extract all cuttings.
