THE K-BOS IS THE AIRBAG FOR THE OIL & GAS INDUSTRY

The Kinetic Blowout Stopper, or K-BOS, is a retrofittable, large bore electrically initiated, pyro-mechanical gate valve which performs the critical function of shearing and sealing during drilling, completions and intervention well control operations.
The K-BOS is designed to shear anything above the bit, and seal instantly no matter the flow – no exceptions. The industry’s first true blowout “stopper” as opposed to current “preventers” – “think of it as the airbag for the oil & gas industry”.

For subsea applications, the K-BOS may be retrofitted to casing shear ram or blind shear ram cavities without disturbing the existing BOP body. Due to its use of pyrotechnics instead of hydraulics, the K-BOS eliminates the need for many subsea accumulator bottles (and their associated weight and maintenance) from the subsea BOP stack. The K-BOS may also be deployed independently of the rig, latched-up directly to the subsea wellhead with the subsea BOP stack latched up above. An overview of this independent configuration may be found towards the bottom of this page.

The primary K-BOS control system is mounted subsea and may operate independently from the surface control systems while allowing for full integration into existing emergency disconnect sequence (EDS) modes and dead-man auto-shear (DMAS) functionality. With the ability to eliminate unshearable and unsealable situations, the K-BOS provides an order of magnitude reduction in enterprise risk posed by blowouts.

This game changing capability combines with the ability to secure the well in a handful of seconds to enable subsea drillers to reimagine dynamic positioning watch circles in deep water, hazardous environments and shallow water.

The K-BOS has been fully tested subsea in the Gulf of Mexico. In the video above, you can see the K-BOS together with a next-generation subsea control system integrated into what is called the aShear system mounted on an LMRP frame and connected to a double body BOP. The equipment was submerged to a depth of 5,100 ft where extensive accelerated lifecycle testing was performed. At the end of more than 5 years-worth of accelerated testing, the ROV was used to trigger the DMAS circuit. The aShear system activates the K-BOS which instantly shears the tubular in the wellbore and, after the tubular falls away into a catch basket, the aShear then closes and locks the blind shear ram.

SHEAR ANYTHING, SEAL INSTANTlY

The K-BOS is rated to shear all typical tubulars, tool joints, heavy casing, landing strings, and BHAs used for a given bore size and can also cleanly shear wireline in the slack condition. The rapid kinetic shearing action leaves a clean fish with minimal deformation and allows the K-BOS to shear and seal in milliseconds with unmatched reliability.

CONFIGURATION OPTIONS TO MEET ANY WELLS PROGRAM

In addition to the integrated retrofit, the K-BOS can be deployed subsea as a rig independent Emergency Shut-in Device, or “E-SID” which is mounted on the subsea wellhead with the BOP stack latched-up above the E-SID.

This configuration allows the game changing shear and seal capabilities of the K-BOS to be deployed rapidly and without integration into the rig for short-term engagements. The completely independent E-SID configuration also allows the K-BOS to serve as an 18-3/4” bore 15ksi rated barrier to enable open water intervention and abandonment operations. The E-SID may also be deployed as a capping stack enhancement.

The video below provides an overview of the K-BOS E-SID configuration and outlines that particular value case in more detail.

 

ULTIMATE RELIABILITY

K-BOS Value Case Summary – Subsea Applications

In the past, the Industry’s emergency well control systems lagged reliability standards of comparable safety functions in other industries. The K-BOS utilizes the highest reliability components and methodologies field proven in safety critical applications during more than 20 years. It’s ability to continuously self-diagnose faults and positively confirm functional availability in real time and while offline to operations creates an opportunity to reduce testing related non-productive time while increasing emergency well control system reliability by 3 to 4 orders of magnitude.

The K-BOS provides a drastic improvement in reliability combined with the ability to stop a full flowing blowout. By eliminating exposure to “unshearable” and “unsealable” situations, the K-BOS provides Operators with a dramatic reduction in Enterprise Risk posed by subsea blowouts. There is significant upside value potential as the K-BOS is adopted across the industry creating the potential for changing the overall well control cost paradigm and allowing for more sustainable and profitable growth in the industry.
