Orca: Innovative Limited Entry Technology
The Orca system is leading-edge technology offering the ability to stimulate with limited entry design replacing plug-and-perf operations. With flexible configuration and tailored grouping abilities, Orca offers a major advantage in cost, stimulation efficiency and ESG initiatives. Orca eliminates the need for wireline, plugs, coiled tubing for clean out and mill outs.
Stuck using Plug-and-Perf for limited entry?
Efficient Limited Entry Options
As interventionless multistage frac sleeve systems have quickly gained popularity in the realm of single-point-entry completions, many operators believe they are tied to using plug-and-perf applications to successfully conduct limited-entry stimulations. There is now a better option.
The Orca offers proven technology while enabling fully customizable port sizing, port numbering and cluster spacing. Based on the field-validated mechanics of the Bowhead, that has over 8,000 tools in the ground, this system uses a precise lock-and-key collet method to open a virtually endless configuration of frac-port clusters per stage by launching a single collet with dissolvable ball.
Tired of birds-nests and pinholes holding up operations?
How It Works
A single individually profiled collet with dissolvable ball is launched and travels through the wellbore, bypassing full-bore unmatched stages until reaching the targeted stage. The collet latches, fully shifts open the valve, and then continues to travel through the first cluster valve of its corresponding stage repeating the same function through the remaining cluster valves in that stage. When it reaches the landing valve, it latches, shifts open and seats, providing full isolation from stages down-hole.
This process leaves the pre-designed limited entry stage, ready to stimulate immediately, with complete full-bore drift to surface. The engineered ports and clusters provide the desired differential pressure at each formation access point and ensures limited-entry frac distribution across the reservoir.
Once the stage has been stimulated, continuous pumping allows the subsequent collet to be launched thus allowing the following stage to be opened, isolated and stimulated without shutting down pumps.
Removing ancillary operations such as wireline and coiled tubing could be your organizations’ solution to inefficient and complex completion projects.

Needing a better solution to milling or slips/debris being left behind?
After all stages have been stimulated and the well is shut in, dissolvable balls flow off collet seats and dissolve completely. Once the balls have dissolved, the well is ready to go on production with all open cluster valves providing full-bore drift and collets within landing valves providing large-bore drift.
No coiled tubing, no milling, no slips/debris from partially dissolvable or millable plugs.
