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.

The Role of Waterways in Configurations: 3 Factors to Consider

Posted by Rod McCoremick on Jan 23, 2017 10:30:00 AM


Choosing a core bit configuration has always been considered to be a bit of a mystery, right up there with how to choose the right core bit. Because there are so many to choose from, drillers usually stick to a few of their favourites for as long as they provide good performance. When performance starts to suffer, they need to try something new.

Fundamental Guide to Choosing the Right Core Bit Configuration

Posted by Rod McCoremick on Dec 12, 2016 10:30:00 AM


The question we hear most often from customers is “how do I choose the right core bit for the ground I will be drilling in?” So last year we wrote a guide on that and it was very popular. Many variables need to be considered including rock hardness, the variability of the rock, and whether it was abrasive, and then you need to choose the right bit range and configuration. While we have scratch tests to help determine bit range, how do you choose the configuration?

5 Precautions to Take When Setting a Wedge

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

 

 

No matter how carefully you planned and drilled, bore holes are rarely straight. Many things can have an effect on the direction of the hole, such as weight on bit, poorly set up drill rig, fractures or voids in the ground formation, bedding planes, or ground that goes from hard to soft. Too often, the path of the bore hole needs to be corrected in order to reach a desired target and that is when you should consider using a wedge.

Time To Go Fishing – 4 Ways to Recover Your Drill Rod

Posted by Rod McCoremick on Oct 3, 2016 10:30:00 AM

 

A surefire way to stall operations and lower productivity is to break a drill rod in a bore hole – a too common occurrence in diamond drilling.

A rod string can break, either from too much pressure or by being dropped, or the bit can melt and fuse to the rock. Certain ground conditions can lead to your equipment being jammed. Clay can swell enormously when water is introduced and this swelling can trap the rod and drill bit. Coming across sand can also be harmful as the sand can collapse around the drilling equipment.

Diamond Tools in Directional Drilling: Making an Informed Choice

Posted by Rod McCoremick on May 23, 2016 10:30:00 AM

 
At some point, every driller realizes that despite precautions and preventative measures, the drill bit can deviate from the trajectory chosen. The degree of the deviation depends on various factors such as the size of the hole, the type of ground, the pressure on the bit and the depth of the hole.

Generally speaking, holes drilled horizontally deviate more than vertical or steep angled holes, holes drilled in variable rock deviate more than holes drilled in competent rock. When your drilling program requires changing the directing of a bore hole, there are a few options to consider.

Push and Pull Diamond Impregnated Bit

Posted by Rod McCoremick on May 2, 2016 10:30:00 AM


Drillers get used to particular types of equipment and have their preferences. Sometimes, because of ground conditions and new challenges or the scope of work, you must try new types of equipment. The truth is that that there are many types of specialized equipment and diamond tools that have been developed for specific situations and it can be interesting to learn about these specialized tools.
