ActiPulse and PowerPulse deliver friction reduction with less pressure loss, longer tool life, and no limit on how far a lateral can reach, advantages that come down to how the tool is engineered, not just what it’s called.
What ActiPulse and PowerPulse Are
ActiPulse and PowerPulse are both variations of the original Impulse Tool, the friction reduction tool the company was founded on. The difference between them is how vibration is controlled, not what generates it.
PowerPulse runs continuous vibration from the moment the rig pumps engage. It’s the simpler, always-on version of the tool, built for runs where friction is a known, constant problem from the start of the lateral.
ActiPulse adds ball-drop, on-demand control on top of the same core mechanism. Instead of vibrating for the entire run, the operator drops a ball to activate the tool only when friction actually needs to be broken, then it can be deactivated the same way. Both configurations run on the same physical tool, and one can be converted into the other onsite using a conversion kit, so a crew isn’t locked into a single mode of operation once the tool is already in the hole.
How It Works: On-Demand Versus Continuous Vibration
The mechanical difference matters more than it sounds. Any tool that vibrates continuously is putting wear on itself and on surface equipment for the entire run, whether or not friction reduction is actually needed at that moment in the well. Over a long lateral, that adds up to unnecessary wear on connections, valves, and surface iron.
ActiPulse’s ball-drop system changes that equation. Vibration switches on only when the string needs it and off when it doesn’t, which does two things: it protects surface equipment from vibration it doesn’t need to absorb, and it extends the working life of the tool across the rest of the run, since it isn’t cycling the whole time.
The valve itself is flex-shaft driven, which keeps pressure drop low. That matters because friction reduction tools compete with everything else in the string for hydraulic energy. A valve that starves the system of pressure to generate vibration is taking that pressure margin away from other tools in the BHA. A low-pressure-drop valve doesn’t do that.
Where These Tools Are Used
ActiPulse and PowerPulse are built for well conditions where friction is the limiting factor, not just an inconvenience. Typical applications include:
- Extended reach laterals requiring multiple friction reduction tools placed along the string to break friction and maintain performance across the full length of the lateral
- Complex well bore geometry, where tool placement has to be planned around doglegs and directional changes rather than run in a straight, predictable string
- Shallow TVD (true vertical depth) wells, or any run where surface equipment needs to be protected from vibration, particularly when multiple friction reduction tools are running at once
- High mud densities and abrasive fluids, which wear down a standard vibration tool faster than a self-lapping valve design does
- Runs where the need for a friction reduction tool isn’t certain, where ActiPulse can be run passively as insurance to reach total depth without committing to continuous vibration for the whole run
Benefits Versus Competitor Systems
1. On-Demand Control
ActiPulse switches vibration on only when needed and off when not, protecting surface equipment and extending tool life across the rest of the run instead of running continuously. Where a competitor’s always-on FRT wears from the moment pumps engage, ActiPulse only accumulates wear during the segments of the run where it’s actually doing work. That’s a meaningful difference on long laterals where a tool might only need to be active for a fraction of the total run length.
2. Best Strike Force Per Unit of System Pressure
When a rig is pressure-limited, this is the differentiator. ActiPulse and PowerPulse deliver the highest strike force at the lowest system pressure requirement, so operators get friction reduction without eating into pressure margin elsewhere in the string. In practice, that means a driller isn’t forced to choose between running an FRT and maintaining pressure for other tools in the BHA. The flex-shaft driven valve design is what makes this possible: it generates vibration without starving the hydraulic system the rest of the string depends on.
3. Stackable for Extreme Reach
Multiple units can run in the same string, so long horizontal wells aren’t capped by what a single friction reduction tool can deliver. Tool count scales with lateral length instead of hitting a hard reach limit. Because ActiPulse units can be sequentially, remotely controlled via ball drop, operators can selectively activate specific tools along the string rather than running every unit continuously, extending both reach and tool life in the same run.
4. MWD Compatibility and Field Flexibility
Valve geometry gives an open pathway for MWD transmission, producing the cleanest pulse of any friction reduction tool in the industry, according to Impulse. That matters directly for directional accuracy: a noisy pulse from the FRT can interfere with the signal quality MWD tools depend on. The tool can also be converted between PowerPulse and ActiPulse configurations onsite, so operators aren’t locked into one mode once the tool is already committed to a run.
Build and Durability
Impulse’s connections are high-torque, balanced, double-shoulder connections at every joint in the tool, a build standard the company states is unique to its tools in the friction reduction tool category. Combined with a self-lapping valve designed to reduce wear from fluid erosion, the tool is built to maintain consistent vibration output across the full length of an extended reach lateral rather than degrading partway through the run.

Frequently Asked Questions
What is the difference between ActiPulse and PowerPulse?
PowerPulse runs continuous vibration once the rig pumps engage, making it the simpler, always-on version of the tool. ActiPulse adds ball-drop, on-demand control on top of the same core mechanism, so vibration switches on only when needed and off when it isn’t. Both are variations of the original Impulse Tool the company was built around, not separate product lines. A crew isn’t locked into one mode either: PowerPulse can be converted into ActiPulse onsite using a conversion kit, so the choice can be adjusted to the run rather than committed to before the tool goes in the hole.
How does ActiPulse reduce friction better than other tools on the market?
On-demand control means the tool isn’t running vibration for the entire length of the run, which protects surface equipment and extends tool life across the rest of the string instead of wearing continuously from the moment pumps engage. That’s paired with the highest strike force per unit of system pressure in the industry, so friction reduction doesn’t come at the cost of pressure margin elsewhere in the BHA. A flex-shaft driven valve keeps pressure drop low, which is what makes that combination of strong strike force and low pressure demand possible in the first place.
Can multiple ActiPulse or PowerPulse tools run in the same string?
Yes. ActiPulse and PowerPulse are stackable, so long horizontal wells aren’t capped by what a single friction reduction tool can deliver on its own. Tool count scales with lateral length instead of hitting a hard reach limit partway through the run. Because ActiPulse units can be sequentially and remotely controlled via ball drop, operators can selectively activate specific tools along the string rather than running every unit continuously, which extends both effective reach and tool life across a single extended-reach lateral.
Is ActiPulse compatible with MWD systems?
Yes. The valve geometry gives an open pathway for MWD transmission, producing what Impulse describes as the cleanest pulse of any friction reduction tool in the industry. That matters for more than just friction: a noisy pulse from the FRT can interfere with the signal quality MWD tools rely on for accurate directional data. Because the tool can also be converted between PowerPulse and ActiPulse configurations onsite, operators aren’t locked into a setup that compromises MWD performance once the string is already committed to a run.
Where can operators source ActiPulse and PowerPulse in Australia and New Zealand?
Tasman Oil Tools is the exclusive distributor of Impulse Downhole Tools across Australia and New Zealand. That means operators in the region can access ActiPulse and PowerPulse through Tasman’s rental fleet, with workshop and field support handled locally rather than through an overseas supplier. It also means Tasman is the point of contact for availability, technical questions, and coordinating tool delivery to site, rather than operators needing to go through Impulse directly for access to the tools in this region.
