The rate of chemical weathering isn’t the same everywhere—it depends on factors like climate, rock type, water flow, and biological activity. Warmer, wetter conditions speed up reactions, while fractures in rocks allow water to seep in and break them down over time....

Chemical weathering involves the chemical breakdown of bedrock and the formation of new mineral products. A detailed treatment of the processes in chemical weathering is found in Anderson and Anderson (2010, p. 183–202), and a very brief overview is provided here. The...

Sedimentary basins are morphotectonic depressions on Earth’s crust, which accumulate a considerable amount of sediments over geological time. Sedimentary basins are the repositories of a great volume of economic deposits, including hydrocarbons, coals, groundwater,...

Types of traps are geological structures that retain hydrocarbons, preventing further movement. They include structural, diapiric, stratigraphic, hydrodynamic, and combination traps formed by rock deformation, sediment movement, or water flow. Understanding these...

Source Rocks: A Petroleum source rock is defined as any rock that has the capability to generate and expel enough HC to form an accumulation of oil or gas. A potential source rock is one that is too immature to generate petroleum but will form significant quantities...

Permeability: Permeability is the ability of fluids to pass through a process material. It is measured in millidancy (MD) or Darcies (D) and expressed by k. According to Darcy’s law, Where, Q = Rate of fww K= Permeability (p1-p2) = Pressure drop across the sample A =...
