ABSTRACT
fault
blocks are definitive
evidence of a fluid seal across faults. A method is proposed for using log-derived and
calculated pressure gradient values to correlate and map pressures on cross sections to
delineate pressure differentials across
fault
zones. These values were calculated and
mapped along a known hydrocarbon sealing
fault
inferred to be a pressure seal in a field
from the Gulf of Mexico. The results indicate that this method can generate a detailed
picture of the fluid and pressure history to aid in the documentation and prediction of
sealing or leaking relationships along
fault
zones.Pay-Per-View Purchase Options
