Pump every stage as designed
If a dart or ball pops through its seat or shifts the wrong sleeve, entire stages can end up in the wrong interval, leaving the rock you designed them for unstimulated. BullsEye measures depth from the water hammer each time a dart or ball seats, a sleeve shifts, or one pops through, so you know it hit the right sleeve before the stage is pumped.
The Risk
When a Dart or Ball Misses
Every stage in a sliding sleeve completion depends on a dart or ball landing where it should and staying there. When one doesn't, a standard pressure chart often can't tell you, and the stage gets pumped anyway.
Pops Through the Seat
The dart or ball doesn't hold on its seat and keeps going. Without isolation, the treatment meant for this stage goes into the interval below, which has already been treated.
Shifts the Wrong Sleeve
The dart or ball lands on or shifts a sleeve other than the one designed for the stage, sending the treatment into the wrong part of the lateral.
The Stage Is Lost
You pay for the fluid, proppant, and pump time, but the interval you designed the stage for never gets stimulated, and its reserves are left behind.
Features
Key Capabilities
Objective Depth at Every Event
Every seat, sleeve shift, pop-through, and pump shutdown sends a water hammer down the well. BullsEye reads its acoustic signature at 40,000 samples/sec and pinpoints the depth to ±20 ft, without any downhole tools.
Confirm the Right Sleeve Shifted
Compare the measured depth of each seat and sleeve shift against your sleeve depths to confirm the dart or ball landed on its target sleeve, so the stage goes into the interval it was designed for.
Catch Real Pop-Throughs, Not False Alarms
On a standard pressure gauge, formation events can look almost identical to a pop-through when nothing actually happened downhole, leaving the call to subjective interpretation. BullsEye gives you an objective depth measurement instead, so you don't react to a pop-through that never happened or keep pumping through one that did.
One Sensor for Dart and Ball Sleeves
A single high-frequency pressure sensor on the wellhead works on dart-activated and ball-activated sliding sleeve completions with zero well intervention. Install it at the start of the job and monitor every drop through the last stage.
How It Works
Four Steps to Confident Sleeve Activation
BullsEye uses acoustic signatures and pressure data to confirm every dart and ball lands on the right sleeve before the stage is pumped.
Install
Attach the high-frequency pressure sensor to the wellhead. Non-intrusive, no well intervention required.
Drop
Drop the dart or ball. The sensor records wellhead pressure continuously at 40,000 samples per second.
Measure
When the dart or ball seats, the sleeve shifts, or one pops through, the water hammer gives an objective depth to ±20 ft.
Confirm
Compare the measured depth to your sleeve depths to confirm the right sleeve shifted before the stage is pumped.
Sleeve Systems
Built for Dart and Ball Sleeves
One surface sensor covers both sliding sleeve systems, so you get the same confirmation however your completion is designed.
Dart-Activated Sleeves
Get an objective depth when each dart seats and when its sleeve shifts, and confirm it's the target sleeve before the stage is pumped. If it lands short or pops through, you know right away.
Ball-Activated Sleeves
Get an objective depth when each ball lands on seat and when its sleeve shifts, and confirm it's the right sleeve before the stage is pumped. If it pops through, you know before the treatment follows it.
Why BullsEye
Eliminate Uncertainty in Sleeve Activation
Traditional dart and ball drops rely on subjective interpretation of a pressure chart. BullsEye turns that pressure data into an objective depth measurement.
