Title: Fault
Seal Analysis in the North Sea
Author(s):
Abstract:
The majority of North Sea structural traps requires that at least one fault
be a sealing
fault
. Over 400 faults from 101 exploration targets and 25 oil and gas fields were analyzed in a regional study of the North Sea. The faults cut clastic successions from a variety of depositional environments (marine, paralic, and nonmarine). The emphasis of the study was on
fault
-related seals that act as pressure or migration barriers over geologic time. Parameters such as
fault
strike and throw, reservoir thickness, depth, net-to-gross ratio, porosity, and net sand connectivity were plotted against seal performance to define trends and correlations to predict
fault
seal characteristics. A correlation appears to exist between
fault
orientation and sealing, although this is not stati
tically significant. Sealing is proportional to
fault
throw normalized as a fraction of the reservoir thickness. The great majority of faults with throw greater than the thickness of the reservoir interval were sealing faults. The most useful parameters in
fault
seal prediction are
fault
displacement, net-to-gross ratio, and net sand connectivity. The conclusions of this study have general applicability to
fault
seal prediction in exploration, development, and production of hydrocarbons in clastic successions in the North Sea and perhaps other areas as well.
