Our Process

We don’t just sell tools – we partner with you to increase effectiveness. We analyze BHA, well profile and drilling performance requirements and discuss specific objectives with your drilling team. This ensures you get optimal performance from your BHA. 

Dual acting configuration - 

Optimal for running in conjunction with vibratory tools/ agitation. 

All of Cougar's ST5 shock tool designs can be configured to a dual-acting configuration, which provides a larger operating range and specifically the ability to accept the pressure pulse from a vibratory tool, allowing proper extension and compression to maximize effective weight transfer.
