Bits ‘n Pieces – The Driller’s Blog

What Kind of Diamond Driller Are You?

Posted by Rod McCoremick on Apr 10, 2017 10:30:00 AM

INTRODUCTION:

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.

Core Matrix Troubleshooting: Polished Core Bits

Posted by Rod McCoremick on Mar 20, 2017 2:23:55 PM

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.

The Importance of Drilling Parameters

Posted by Rod McCoremick on Mar 7, 2017 9:14:49 AM

 

Drilling parameters play a large role in helping drillers achieve a good ROP (rate of penetration), superior drilling performance and long bit life. They are basic recommendations that help guide a driller avoid burning bits or damaging other drilling equipment. Keep in mind that there is a relationship between the drilling parameters and all others factors in drilling, such as the diameter of the equipment of you’re using, rock hardness or ground variability. Understanding how to adjust drilling parameters can help drillers improve performance in difficult drilling situations. We’ll look at a few of them here.

Large Diameter Single Tube Core Barrel Saves the Day

Posted by Rod McCoremick on Feb 20, 2017 11:00:00 AM

Sometimes I like to write about how a customer may have solved a particular drilling problem. Like a brainstorm, learning about one company’s ideas can inspire others to find different solutions. So today’s blog is about how we helped a customer in the USA come up with a solution to their drilling challenge.

Core Matrix Troubleshooting: Overly Exposed Diamonds

Posted by Rod McCoremick on Feb 13, 2017 10:30:00 AM

 

We’ve talked a lot in previous blogs about the importance of choosing the right core bit and the right core bit configuration, so I think it is time we talk about getting the most out of your core bit. There are many variables that can cause a really good core bit to underperform. It can be a change in ground conditions, drilling parameter or simply lack of experience.  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.

Bore Hole Maintenance 101

Posted by Rod McCoremick on Nov 21, 2016 10:42:25 AM


In diamond drilling, your bore hole plays an important role and will have a large impact on your drilling performance.  A bore hole is like a road – it must be maintained. If you want the road that transports your equipment to be even, smooth and durable, you need to perform regular maintenance. Large trucks and equipment that run over it hourly can be damaged if the surface is crumbly, and full of pot holes. Your bore hole needs the same kind of care. Your bore hole is like a road that transports your drilling equipment.

Diamond Drilling 101: No Water Circulation

Posted by Rod McCoremick on Nov 14, 2016 10:30:00 AM

 

Unless you hear from another driller who has already drilled in your zone, there is no way to tell if you will encounter a problem with water circulation. Some areas are notorious for having voids, fractured ground or underground rivers. These include Nevada and the western USA, as well as a large part of South America. Large geological faults that run through these areas are often to blame for the ground conditions.

5 Good Reasons to Fill Out a Core Bit Tag

Posted by Rod McCoremick on Nov 7, 2016 10:30:00 AM

 

Most of us know what a bit tag is – that little piece of paper that comes with a new core bit. However, a lot of drillers don’t fill out the information requested on the tag. They’re “too busy” or they think they have better things to do…like drill. Yeah, we get it, but those bit tags can help make your life easier and it is a good habit to get into.

How Fractured Ground Conditions Affect Diamond Drilling

Posted by Rod McCoremick on Oct 24, 2016 10:30:00 AM

 

The kind of ground conditions a driller encounters will play a huge role in how the project goes and the types of decisions he will need to make.  Ground conditions include more than just the hardness of the ground and choosing the right matrix for a particular hardness. While important, other decisions will need to be made.
