REAL-TIME INTELLIGENT FRACTURING: Optimizing fracture surface area Delivering Second-by-second fracture measurements and active fracture guidance to visualize rock response and optimize fracture surface area Providing world class completion and reservoir engineering technology to provide further insight into unconventional asset development
- 2. 2 Why ShearFRAC®? Blanket Recipe Rock properties change from stage to stage. The application of rate and proppant should too. Expensive Data Turn low cost surface pressure data into high value actionable decision making. Energy Transfer Execution mindset away from sand disposal mentality. Working proppant vs. conductive proppant. Improved proppant transport. Digital Transformation Real-time rock response for interactive fracturing. More attention on your biggest spend. Quality control. Data Quality Historical frac data missing/repeating values from filtered data. Sensors used to control equipment.

- 4. 4 FracBRAIN® displays active well rock response, fracture surface area, and FDI visualization FracBRAIN® is a completions manufacturing visualization dashboard that measures how the formation is fracturing each second and how the active well is interacting with offset wells, providing intelligent recommendations for adjustments to increase fracture surface area and decrease FDI’s Live stream fracture surface area measurements to the field which are used to make second- by-second, real-time adjustments to improve completion effectiveness of each stage a real-time, web based, completions platform
- 5. 5 Variations in Geology Jo Mill: - fine sandstone - more permeable - thicker bedding - low fracture intensity - low magnitude breaks Wolfcamp A: - organic-rich shale - high concentration of micro-fractures - highly laminated - high fracture intensity - high magnitude breaks BEG Reservoir Characterization CoreLab Depositional Systems We measure how the rock is breaking, results impacted by geology & geomechanical stresses
