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.
