Detailed explanation-1: -Source rocks are usually shales or limestones (sedimentary rocks). To be a productive source rock, the rock needs time to mature (time to form the oil and/or gas) and the hydrocarbons need to be able to migrate to a reservoir or seep.
Detailed explanation-2: -A rock rich in organic matter which, if heated sufficiently, will generate oil or gas. Typical source rocks, usually shales or limestones, contain about 1% organic matter and at least 0.5% total organic carbon (TOC), although a rich source rock might have as much as 10% organic matter.
Detailed explanation-3: -Source rock potential is evaluated based on three parameters (organic amount, organic type, and maturity). Analytical instruments, such as elemental analyzers, Rock-EvalĀ® instruments, and vitrinite reflectance microscopes, are used for analysis of outcrop samples, well cuttings, and cores.
Detailed explanation-4: -Source rocks are the product of the deposition, preservation, compaction, and lithification of detrital sediment and organic matter at the sediment water interface in lacustrine or marine basins.
