Introduction
The over pressurized formations are a worldwide phenomenon causing a lot of serious difficulties while drilling oil and gas wells, so well’s casing program is designed to isolate the deferent pressure regimes along the well borehole to minimize drilling problems.
The over pressure formation/layers are defined as any pore pressure that is greater than the hydrostatic pressure of the formation water occupying the pore space which can occur at any depth
Some geological mechanism is providing a seal or cap to interfere with the fluid column and preventing it from achieving normal hydrostatic equilibrium.
The cause of over pressure is attributed to a combination of various geological, geochemical, geothermal and mechanical changes such as
• Clay compaction & digenesis
• Incomplete sediment compaction
• Faulting & Trust Faulting
• Structure Changes during compaction
• Massive rock salt deposition
• Salt diaperism
• Tectonic compaction
• Re-pressuring from deeper levels
• Generating of hydrocarbons
