Abnormal Pressure Caused By Faulting

Fault is a discontinuity in a geological structure and it sometimes can create abnormal pressure. Hence, you need to really understand how the geological fault can cause higher pressure even though it comes from the same reservoir.

There are three fault types which are as follows;

  • Strike-slip, where the offset is predominately horizontal, parallel to the fault plane.
  • Dip-slip, offset is predominately vertical and/or perpendicular to the fault plane.
  • Oblique-slip, combining significant strike and dip slip.

Abnormal Pressure from Anticline Gas Cap

I got a question about how an anticline gas cap can create the abnormal pressure. The anticline with gas cap can be the potential high pressurized zone. Because of reservoir connectivity between fluid underneath gas and gas reservoir, it can generate abnormal pressure. This example below demonstrates you how this situation could happen.
