Posted by Rod McCoremick on Apr 17, 2017 10:00:00 AM

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.

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.

Drill Site Security: Changing of the Seasons

Posted by Rod McCoremick on Apr 4, 2017 11:00:00 AM

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.

How to Choose the Size of Your Reaming Shell

Posted by Rod McCoremick on Mar 27, 2017 11:00:00 AM

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?

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.

Top 10 Skills for Diamond Drillers - Not Drilling Related

Posted by Rod McCoremick on Mar 14, 2017 9:08:11 AM

 Part of being a good diamond driller is learning and mastering certain skills, like how to fix a deviated bore hole or how to sharpen a polished core bit. Beyond those skills, there are other basic skills that every guy should know in order to be capable and effective in the world in general, so we thought about what those skills should be. 

We came up with a long list – too long for one blog post so we’ll do a few installments in the weeks to come. For now, here are 10 skills you should master.

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.

Choosing Core Bit Configurations: Discharge Options

Posted by Rod McCoremick on Feb 27, 2017 11:15:00 AM

 

In this blog we will continue to try and demystify how to choose a core bit configurations. A few weeks ago, we tackled the role of waterways and now we will look at discharge options. Remember that picking the right core bit is an important decision that impacts drilling performance and you need to consider several variables.

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.
