Predict & Evaluate the Geomechanical Response
Given the importance of the natural fractures, it is important to account for their effects during the design of any stimulation program. SIGMA³ has developed a unique workflow that uses geomechanical technology to help operators predict and evaluate the geomechanical response of the reservoir to hydraulic stimulation.
Combining elements never before used in the oil & gas industry, this new technology takes into account the propagation and interaction of multiple hydraulic fractures with natural fractures to predict differential stress, strain (good proxy for microseismicity) and frac energy to enable engineered completions and optimized reservoir drainage.
By combining classical frac design with pseudo 3D models and a detailed description of the interaction between the hydraulic and natural fractures, this interaction is quantified and used to adjust the frac design in the pseudo 3D models.
You can reduce completion cost and optimize SRV and production when you can:
- Simulate interaction of hydraulic fractures & natural fractures
- Predict differential stress, reservoir strain, microseismicity & frac performance
- Use seismically derived 3D pore pressure & frac pressure to help estimate geomechanical properties, including closure stress
- Optimize completion & frac designs
