With the warm weather approaching, it will soon be the time to fire up the BBQ and start cooking outdoors. There’s nothing like manning the fire with a beer in on hand and a spatula in the other, cooking a beloved favourite like hamburgers. There is also something about roasting raw meat over a flame, with the scent wafting up your nose that just can’t be beat.
It’s been a while since we’ve done a blog on matrix troubleshooting. Core bits play an integral role in getting great drilling performance and many things can cause a bit to underperform. One of the best ways to determine what is off is to examine the wear profile of your bit crown and change drilling parameters if necessary. Today, we’ll look at burnt core bits, some of the causes and some of the solutions.
I’m often going on about how choosing the equipment for the type of ground you will be drilling in is the first step to success and good drilling performance. Choosing the right drilling fluid additive to match the ground you will be drilling in beforehand, will make a world of difference. This is certainly the case in ground with clay or shale. Swelling clay can have disastrous results on your drilling operation.
Losing equipment in a bore hole and having to go retrieve it is called fishing and no diamond driller wants go fishing. The equipment has become stuck, lost, or broken off but either way it is obstructing the bore hole.
Many earlier blogs have been written on drilling fluid additives and how they can bring great benefits to a drilling operation. Benefits like longer life for your core bits, less torque, reduced rust, less wear and tear, better core recovery, improved drilling performance and more. But before you can reap all these benefits, you need to know how to mix them properly. There are four simple tools that you should have in your toolbox that will help ensure the best drilling mud.
A few weeks ago we published list of the top 10 skills diamond drillers should have mastered - skills that were not drilling related. The list we had come up with was too long to publish in one blog, so we published the first 10. Here now is the follow up to that blog – the next top 10 skills that you may want to master in order to be a competent man in today’s world.
As you spend more and more time on a drill site, you start to recognize certain similar behaviours in fellow drillers. You can start to see types of drillers that are different from each other. I was asked the other day, what type of driller am I, and that got me thinking about how to describe the different types of drillers that I spend time with and have been. Here’s what I came up with.

Regardless of what part of the world you are in, when the seasons change, you need to make sure safety considerations also change. In North America, spring is around the corner, and in the southern hemisphere, autumn is coming. Regardless of the temperature, let’s review some basic security guidelines.

I have noticed that there are a lot of drillers who use the 6 inch reaming shell pretty exclusively, so in this blog I wanted to talk about the other sizes available and how to know when you should use another size. Reaming shells are used to maintain the diameter of the bore hole and to make sure other drilling equipment does not get stuck down the hole. The outside surface of the reaming shell has natural and synthetic diamonds embedded in a resistant matrix.
Reaming shells come in 6, 10 and 18 inches. How do you know when do you use each size?

Many of our previous blogs are about the importance of choosing the right core bit and the right core bit configuration. Recently I started discussing some of the reasons that core bits underperform, even if you have chosen the right ones. Some of the reasons involve changes in ground conditions or not using the best drilling parameters for the drilling project. One of the best ways to determine what is off is to examine the wear profile of your bit crown and change drilling parameters if necessary. An earlier blog looked at the problem of over exposed diamonds and this time we will look at core bits that are polished.
