ABAL's in-house Faultmap software is used for fault analysis, fault seal probability (FSP) calculations and shale smear computations. From it, we can output simple fault plane diagrams, plots of throw variation along faults, shale smear evaluation plots and fault seal probability maps.
Fault analysis is a key tool for evaluating the integrity of seismic interpretation and structure mapping. It comprises a suite of techniques used to examine and verify a variety of mapped fault parametres e.g. fault throw length, and spacing.FSP maps allow fault seal potential both along fault strike and from fault to fault to be evaluated - see the example below. They are invaluable for assessing migration pathways into prospects, evaluating compartmentalisation and identifiying potential leak points on faults.
To see an example of how we use fault analysis and FSP maps, see our example of a fault seal project.
Our new fault properties tool, FaultRes, allows fault seal parameters, and other fault properties, e.g. permeability, damage zone width, to be mapped across fault planes in 2D.
