New Baker Hughes Multistage Stimulation Technologies Enhance Unconventional Hydrocarbon Recovery
HOUSTON, TEXAS – Nov. 9, 2011 – Baker Hughes offers three multistage stimulation technologies that provide operators with time- and cost-efficient completion solutions to significantly increase production, improve recovery and preserve water during the pressure pumping process.
“It takes tailored fracturing and stimulation solutions to produce efficiently in the diverse shale formations that stretch across our globe where the minerals, structure and geology all differ vastly,” says Neil Harrop, president of Completions and Production for Baker Hughes. “FracPoint and OptiPort provide efficient technologies to complete and fracture a wide array of formations, where each has its own unique characteristics. These technologies allow us to customize a solution that maximizes results and minimizes impact.”
Baker Hughes’ FracPoint multistage completion system uses openhole packers to isolate multiple stages and ball-activated sleeves to divert the frac treatment. The system’s EX-C sleeves extend the capability of ball-activated systems, enabling more contact with the reservoir while maintaining fracturing efficiency. The sleeves contain a patented ball seat that collapses underneath the ball to provide additional surface area between the ball and ball seat, providing enough additional support to achieve fracturing pressures.
FracPoint EX-C sleeve system benefits:
- Increases the number of ball-activated stages that can be performed to 40
- Increases contact and connectivity to the reservoir
- Maintains the fracturing efficiency of ball-activated systems and saves pumping time
A significant addition to the FracPoint system is the IN-Tallic disintegrating frac balls. These revolutionary frac balls are made of a new nanomaterial developed by Baker Hughes’ nanotechnology scientists. The material has the compressive strength of steel, but is lighter than aluminum. The balls were developed to disintegrate in most common wellbore and fracturing fluids, so no special fluid mixture is required, enabling operators to remove the frac balls from the well without having to mill them out.
FracPoint IN-Tallic disintegrating frac balls benefits:
- Removes frac balls from the well without through-tubing intervention
- Ensures that balls do not block production due to differential pressure between zones
- Avoids the formation of a debris barrier caused by a fracturing ball pile-up
Baker Hughes’ OptiPort multistage fracturing system includes pressure-balanced sleeves to divert the fracture, and either cement or openhole packers to isolate each stage. The sleeves are opened by placing a coiled tubing packer between the two ports on the sleeve and applying pressure to create an offset. The coiled tubing assembly also allows real-time downhole pressure monitoring during fracturing, which provides the information needed to help prevent screen-outs. If a screen-out does occur, the OptiPort system greatly reduces nonproductive time, because the coiled tubing assembly is already equipped for clean-out.
OptiPort system benefits:
- Offers a virtually unlimited number of stages and controlled placement of fracs
- Provides real-time pressure monitoring to offer a better understanding of what is happening down hole
- Uses 20% to 40% less water and can save 10% to 30% on operation time
- Enables treatment design flexibility
- Optimizes reservoir drainage by allowing tighter frac spacing
- Allows for smaller fracs using less horsepower, reducing the overall footprint
