OPPtimal Fault Extraction (OFE)
Increasing resource recoveries & cheaper, safer and more successful operations
AAPG-awarded, world-first method to generate reliable high-resolution fault volumes from seismic data and link these to various Drilling, Mining, Exploration and Production observations.
The method allows to:
- identify and predict fluid barriers, fluid conduits, fault-related mineralisations or drilling & mining hazards,
- identify and predict fault penetrations in wells or mines,
- better understand, predict and mitigate drilling, mining and production issues,
- optimally place wells and mines,
- reduce risks and costs,
- increase resource recoveries, and
- optimise resource developments.
Pro/con
“Innovator in Geosciences Technology” Award from AAPG in 2013
The new technology method challenges many perceptions of what can be resolved from seismic data, how many smaller-scale faults are present in the subsurface and how these affect drilling & mining operations and the production of resources
Faster, cheaper and more accurate fault identification compared to subjective and time-intensive manual fault mapping
Improved structural definition and understanding of structural geometries and fault/fracture populations
Proper quantification of fault certainty/confidence and fault properties (size, orientation, throw, frequency, density)
Identification or verification of fault intersections in wells or mines
Improved understanding and prediction of fault-related drilling or mining issues: fluid losses/gains, shallow gas, wellbore stability/integrity, well losses, gas kicks, roof collapse, mine losses, water inflow, outbursts, microseismic events, etc.
Improved understanding and prediction of fault-related production issues: fracture productivity, flow enhancement, water or gas channeling, cross-flow between zones or wells, boundaries/baffles to flow, compartmentalization, juxtaposition, etc.
Optimal placing of future wells or mines: drilling and production risk mitigation, direct targeting of productive fault & fracture networks (sweet spots) and undrained fault compartments etc.
