The Bowhead system has been tested in diverse formations and experienced rapid global adoption across the most prominent geographies, including Canada, China, Russia, the Middle East, and regions in the United States, including Eagle Ford, Permian, and Bakken. Our technology has successful run over 11,000 runs and counting.
Bowhead
The Bowhead completion system is a sleeve based downhole tool technology. It relies on a series of unique profiles to enable a specific ball/collet pair to land in a corresponding piston/housing set. The valve opens with the mechanical shifting of the inner piston.
Installation of the valve in a wellbore occurs in two phases:
- A series of housings with inner sliding pistons are installed with the production casing. Each piston is pinned in the closed position to cover ports in the housing. Each piston has an internal diameter (ID) profile that is unique.
- A ball/collet combination is pumped during hydraulic fracturing operations into the well bore. The collet outer diameter (OD) has a profile section that is matched to the unique ID profile in a particular piston.
The profile designs of piston ID and collet OD are known and engineered to ensure that each ball/collet lands in the corresponding piston/housing and together operate as a valve. The piston and collet lengths, allow for many profiles to be created and have a theoretical capacity of over 300 unique profiles. To date the Bowhead technology has been installed and successfully activated (pistons shifted) in wells with up to 220 valves.
The ball/collet and housing/piston technology configuration, with the unique leaf spring profile length, is used in the core Bowhead valve, and has been evolved to cover other applications.
Orca
The Orca multi-valve system was created to address multi-cluster stimulation with similar operational efficiencies to the Bowhead in terms of mechanical parameters. The Orca system is designed to allow a single collet to open multiple valves to create multiple entry points in each stage. This provides a direct alternative to legacy Plug and Perf operations with multiple entry points in a stage, equivalent to a series of perforation clusters.
The Orca system consists of a series of piston/housings with a common piston ID profile. The pistons have a release mechanism that allows the ball/collet to seat and shift the valve open, then once shifted, the piston releases the collet/ball to continue downhole.
A single ball/collet is launched during continuous pumping, then lands and shifts the upper piston open. Once the upper piston opens, the ball/collet is released and continues downhole to the next piston/housing. The same ball/collet will land in the next Orca piston/housing and shift open the piston exposing the housing ports. This process repeats until the lowest valve provides a permanent landing ring, and the ball/collet is retained.
The ports in the Orca valves are fitted with a perforated burst disc that limits any leakage of proppant slurry during the short time while the ball/collet progresses through and activates the multiple valves. Once the final valve is open, the pressure increases and opens all discs so that the string of Orca valve ports will simultaneously allow access for fluid to be able to commence frac operations.
Tarpon Downhole Cluster Anchor
The Tarpon Cluster Anchor is designed to redefine efficiency and reliability in oil and gas completions. This innovative, dissolvable frac plug anchors securely in a casing coupling profile or sub, eliminating the risk of slippage. Unlike conventional plugs, it avoids hard buttons, wear studs, or large elastomer debris, ensuring a clean and streamlined operation.
Robust Mechanical Seal - The Tarpon Cluster Anchor boasts a robust metal-to-metal seal, capable of withstanding a 10k psi differential pressure, and features a ball-in-place mechanism that flows off the seat effortlessly during production flowback. Precision placement is achieved using the Baker Setting Tool (BST), eliminating the need for the plug to 'flow' down into the collar profile. Designed for simplicity and durability, it performs exceptionally well even at greater depths.
