At the Bottom of the Bore Hole: How Not to Ruin Your Core Bit

Posted by Rod McCoremick on Jun 20, 2017 10:00:00 AM

In this blog, our last installment on handling core bits, we look at problems that can happen at the bottom of the bore hole when you’re adding or changing a new core bit. I always say that choosing the right core bit and bit configuration is one of the most important decisions you have to make to ensure you get the best drilling performance. You also need to make sure you handle them properly so that they get to the drill the ground they were chosen for.

On the Way Down the Bore Hole: How Not to Ruin Your Core Bit

Posted by Rod McCoremick on Jun 13, 2017 2:00:00 PM

Last week we looked at how experienced diamond drillers can get the best performance and longest life from their drilling equipment by avoiding common pitfalls in handling core bits. Often, core bits get damaged before they’re even used. You take the time to choose the right bit and the best configuration, so you want to get the longest bit life possible. Last week we looked at some problems that can happen above ground – this week we’ll examine common problems that happen all the way down, when you’re adding or changing a new core bit.

How Not to Ruin Your Core Bit Before Using – Above Ground

Posted by Rod McCoremick on Jun 6, 2017 10:30:00 AM

Experienced diamond drillers are always looking to get the best drilling performance and longest life from their drilling equipment. Sometimes core bits get damaged before they’re even used. After careful deliberation over choosing the right bit and the best core bit configuration, no one wants to ruin a bit before you start drilling. Let’s look at some problems that can happen above ground when you’re adding or changing a new core bit.

5 Reasons You Need Thread Compounds and Lubricants for Your Drill Rods

Posted by Rod McCoremick on May 30, 2017 2:00:00 PM

Drill rods are a hugely important part of your drilling equipment and how you take care of your drill rods can have a major impact on your drilling performance. The regular use of drilling lubricants and thread compound is imperative for breaking in and maintaining a healthy drill string and helps avoid many problems. Here are a few reasons you need to use thread compounds and lubricants, and the purpose of each.

Matrix Troubleshooting: Burnt Core Bits

Posted by Rod McCoremick on May 15, 2017 10:00:00 AM

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.

Diamond  Drilling in Ground with Clay or Shale

Posted by Rod McCoremick on May 8, 2017 1:51:37 PM

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.

A Primer on Recovery Tools in Diamond Drilling

Posted by Rod McCoremick on May 1, 2017 10:30:00 AM

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.

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.
