  • Diamond drillers can fall into a routine of using the same equipment over and over. Why not? If it isn’t broken, don’t fix it. This is especially true if you are used to drilling in the same region where ground conditions may not vary all that much. However, you may then find yourself drilling in another part of the country, or the world, with conditions that require a different type of equipment.

When Picking Water Swivels, Are You Drilling Shallow or Deep?

  • Water swivels may not be the first piece of equipment that comes to mind when you think about diamond drilling. The rig, the rods and the core bit would likely pop in first. Yet the water swivel has an integral role to play in the drilling process. In surface drilling, the water swivels are responsible for delivering a sufficient amount of flushing fluid to the bit and for hoisting the drill rods in and out of the bore hole.

Blocked Core in Dry Hole Drilling

  • In our last blog, we looked at the expression “pushing a block”, what it meant and why drillers should never try to advance in a hole when the core is blocked. However, in many parts of the world, especially where dry hole drilling is common, or when the hole is very deep, different advice and procedures should be followed. We are going to look at these different situations and the recommended procedures.What is important to understand is that core can block whether you are in a shallow hole or a deep hole, whether you are drilling in Nevada or in South Africa, and whether you are drilling with water or without water. In the case of drilling without water, drillers who are accustomed to these conditions often do not use shut off valves.
