MORE THAN ONE WAY TO GET STUCK


Nothing is as discouraging as becoming “stuck in the hole”, yet is it not uncommon in drilling.
While there are many ways you can be stuck in the hole, they all have the potential to stall operations and result in lost productivity.

 

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.


On the other hand, the rod string can also break, either from too much pressure or by being dropped, and you will need to try and retrieve it. Finally, a bit that has melted and fused to the rock is a bad situation that will stop operations quickly.

 

In each case, especially if you have achieved a significant depth in drilling over a long period of time, it is preferable to try and retrieve what equipment you can than to start over drilling a new hole. Different methods and DTH products are available depending on the situation.

Tool can help


If you have dropped your rod or it has broken in the hole, you can use recovery toolsfishing tools, or casing cutters to try and retrieve the rod.
If unsuccessful, wedges can be used to deviate from your original borehole.

 

Some guidance in proper hole maintenance, and how to use water to improve conditions can also be helpful.
Our technical onsite support team can visit a drill site and offer corrective solutions quickly so you are up and running as soon as possible.
