FSP is a tool developed to screen faults near injection wells and estimate the potential for fault slip induced by fluid injection. It uses probabilistic methods to estimate the cumulative probability of a fault slipping due to increased pore pressure.
- Probabilistic and Deterministic Models: FSP provides both deterministic and Monte Carlo probabilistic approaches for estimating fault slip.
- Input Parameters: Supports input of fault strike, dip, well locations, injection rates, hydrologic parameters, and mechanical stress state parameters.
- Hydrology Model: Includes a simplified radial flow hydrology model, allowing users to relate injection to pore pressure changes.
- Monte Carlo Simulations: Uses Monte Carlo analysis to calculate probabilities of fault slip as a function of pore pressure increase.
- Mohr-Coulomb Slip Criteria: FSP calculates pore pressure to slip on each fault using deterministic geomechanical modeling.
- Monte Carlo Analysis: Probabilistic simulations are run to yield the probability of each fault slipping, considering uncertainties in input parameters.
- Hydrology Model: The hydrology model assesses specific injection scenarios, providing pore pressure changes to be used in the fault slip analysis.
- Results: FSP produces visual outputs including Mohr diagrams, fault maps, and cumulative distribution functions (CDF) of fault slip probability.
