CASING COLLAR
LOCATOR
The patented Yellow Jacket Casing Collar Locator (CCL) is an upgraded version of the industry-standard CCL design. Design enhancements such as double wound coil, pressure bulkheads, and stronger, permanent magnets provide a better functioning, longer lasting tool.
FEATURES
Cleaner signal
- Increased wound length and dual coil winding increase signal strength and clarity while providing system redundancy
- Stronger, permanent magnets enable higher feedback levels
Reduced risk of flooding
- Pressure bulkheads on both ends prevent CCL flooding due to seal failure above or below the CCL
Longer lasting
- Tungsten carbide inserts protect the housing and subs by reducing wear on subs and housing
- Double wound coil provides a back-up system: if one strand breaks, you still get a signal
- Permanent magnets never require recharging
- Shock-proof PCB diode assembly
Compatible with industry standards
- Industry-standard connection threads
- High nickel alloy housing is non-magnetic and is suitable for harsh environments (CO2, H2S)
- Housing material meets API 5CT and NACE NR0175 standards

BOTTOM-SET PLUGS DON’T WORK, BUT DISSOLVABLES STILL CAN.
Many operators tried dissolvables early on and walked away after disappointing results. But dissolvables weren’t the problem. The design was.
Bottom-set plugs removed the mandrel and shortened the tool to reduce magnesium cost. That compromise sacrificed the structure needed to maintain reliable isolation.
Now that dissolvable materials are more affordable, operators no longer have to accept that compromise. Top-set fixes the problem.

We’re looking for a Business Intelligence Analyst who knows how to turn data into actionable insight. You’ll be working across teams to analyze performance, build reporting, and support real operational decisions — not just dashboards. If you’re comfortable digging into data and delivering answers that actually impact the business, take a look.

BOTTOM-SET PLUGS DON’T WORK & THE DATA IS NOW PROVING IT!
For years, operators suspected something wasn’t right with bottom-set dissolvables. The field experience was already telling the story. Now the data is starting to confirm it.
Recent reports from DarkVision and other studies suggest bottom-set dissolvable plugs can fail at rates approaching 40%. Isolation failures erase any savings from a cheaper plug.
The data confirms what the field has already experienced - bottom-set designs fail to deliver reliable isolation.

Next week, we are back in beautiful Lake Louise for the SPE Drilling & Completions Workshop. Stop by Booth 5 to connect with our team and learn how our integrated plug-and-perf systems are helping operators improve efficiency, reliability, and performance across every stage.
BOTTOM-SET PLUGS DON’T WORK�BECAUSE PLUGS NEED LENGTH AND MASS.
Successful plugs aren’t tiny. They require enough length and mass to maintain compression on the sealing element and hold slips engaged under load. Composite plugs have always followed this principle. That’s why they are longer and built around a mandrel.
Bottom-set dissolvables were designed to be as short as possible to reduce magnesium cost. That design decision removed the structure needed to maintain reliable isolation.
Short plugs may save material. But they don’t hold pressure.

Today we celebrate the resurrection of Christ and the hope, grace, and new life it represents. Wishing our customers, friends, and families a blessed and meaningful Easter.
