Multi-Stage Fracturing Tools
Liner Top Packer
Description
The Liner Top Packer is a hydraulically actuated permanent packer that is set in the intermediate casing string in Open Hole Multi-Stage Stimulation System. The packer provides an anchor point for the open hole section of the system.
The Liner Top Packer is carried in on a solid nut running tool that rotationally releases from the packer once all equipment has been set. A frac string with a latch seal assembly can then be stung into the Liner Top Packer to conduct
fracturing operations.
Features
- High pressure and tensile ratings designed to withstand forces created by fracture treatments.
- Full drift liner capabilities eliminates estrictions. Interlocked expandable metal back-up rings prevents elastomer extrusion.
- Tension/compression full circle slips provides superior anchoring capability.
Multi-Ball Frac Sleeve
Description
The Multi-Ball Frac Sleeve is a ball activated ported sleeve used to fractureformation intervals with Bakken Buster Open Hole Multi-Stage Stimulation System. Each Sleeve uses an incrementally sized ball seat that coincides with a specific diameter of ball that opens each individual sleeve. ball seats are designed to ensure high volume frac treatments without the concern for seat erosion while the ballseats can be milled out to full liner drift equirements. The unique design of the ball seats also promotes full formation production potential
during ballflow back operations. The shifting balls are field proven and are designed to provide high impact resistance during ball seat landing, have high compressive load capability during fracturing operations, and have a low specific gravity to promote flow-back.
The Liner Top Packer is carried in on a solid nut running tool that rotationally releases from the packer once all equipment has been set. A frac string with a latch seal assembly can then be stung into the Liner Top Packer to conduct
fracturing operations.
Features
- Full liner drift capability after seat mill-out.
- Locking internal components promotes fast seatmill-out.
- Unique seat geometry prevents ball/debris from plugging seat during flow back operations.
- Compact design to facilitate easy open hole installation.
- Up to 15,000 psi differential pressure capability to fracture tight formations.
- Field proven ball technology delivers reliability.
- Large port flow area to prevent screen outs.
Open Hole Hydraulic Frac Packer
Description
The Open Hole Hydraulic Frac Packer is a key component of Bakken BusterOpen Hole Multi-Stage Stimulation system. Each packer provides reliable openhole pressure isolation to divert fracture treatments into selective intervals.The packer’s unique simplistic design promotes reliability without sacrificing performance. If desired by the operator, multiple packers can be cost effectively stacked together along the liner within an interval to create multiple isolation points in open holes with questionable formation integrity.
Features
- Full bore liner ID through the packer to
- eliminate restrictions.15000-10,000 psi differential pressure rating to fracture tight formations.
- Compact design to facilitate easy open hole installation.
- Unique elastomeric element design for mproved pressure competency.
- Can be economically stacked to increase isolation reliability.
Open Hole Swell Packer
Description
The Multi-Ball Frac Sleeve is a ball activated ported sleeve used to fractureformation intervals with Bakken Buster Open Hole Multi-Stage StimulationSystem. Each Sleeve uses an incrementally sized ball seat that coincides witha specific diameter of ball that opens each individual sleeve. ball seats aredesigned to ensure high volume frac treatments without the concern for seaterosion while the ballseats can be milled out to full liner drift requirements. Theunique design of the ball seats also promotes full formation production potentialduring ballflow back operations. The shifting balls are field proven and aredesigned to provide high impact resistance during ball seat landing, have highcompressive load capability during fracturing operations, and have a low specific gravity to promote flow-back.

Pressure Actuated Valve
Description
The Pressure Actuated Valve is the lower-most frac sleeve in Hole Multi-StageStimulation System. The sleeve is designed to function open by creatingdifferential pressure in favor of the liner to fracture or circulate into the choseninterval in the wellbore. The actuation of this valve allows for ball drop operationsto commence and function the remaining Multi-Ball Frac Sleeves along the horizontal wellbore from the bottom up.
Features
- Full drift liner ID through the valve to eliminate restrictions.
- Externally exposed shear screws to customize opening pressure.
- Compact design to facilitate easy open hole installation.
- Shifting valve locks open to prevent valve closure during the production phase.
Toe Valve
Description
The Toe Valve is a ball-actuated liner blanking device that permits the activationof all hydraulic equipment in Open Hole Multi-Stage Stimulation System. Thevalve incorporates an internal locking device to prevent the valve from openingonce closed. Specific internal geometric flow ports with bypasses direct fluid
flow more gradually reducing the chance of plugging while circulating.
Features
- 15,000psi burst capability when closed.
- Compact design to facilitate easy open hole installation.
- Shifting valve locks closed to prevent valve from
- opening.
