The petroleum system (Magoon and Dow, ) places the source rock as the first and foremost element of the geological system required to produce a petroleum play (Allen and Allen, ).Recently, source rocks have also become unconventional economic reservoirs. A source rock contains a significant volume of organic matter and is capable of expelling petroleum when by:   The obtained data show that the total organic carbon content (TOC) values for the Meem and Lam source rocks are between and wt% indicating fair to good source rocks. Source Rocks, Types and Petroleum Potential. Pp. (27) Henrik I. Petersen. Abstract. Petroleum generating source rocks can be lacustrine, marine shale, marine carbonate or terrigenous/coaly, generally corresponding to Type I, Type II, Type II-S and Type III kerogen based on source rock screening data (Rock-Eval pyrolysis and TOC determination) plotted in modified van .

In a conventional hydrocarbon system, Total Organic Carbon (TOC) is a critical parameter to assess the quality of the shale source rock. A drop in pressure during core retrieval can lead to.   Crude oil is the parent source of all petroleum hydrocarbons and is the fossilised remains of prehistoric algae and zooplankton which have undergone catagenesis to produce hydrocarbons. It is essentially a complex mixture of hydrocarbons and, as the name suggests, its composition is predominantly carbon and hydrogen. Petroleum Hydrocarbons (PHCs) is the name given to a very broad range of chemicals that comprise oil and products refined from oil, such as gasoline and diesel. This mixture of chemicals can also be described by common chemical characteristics such as boiling point ranges or size of the molecules. Harry Dembicki, Jr., in Practical Petroleum Geochemistry for Exploration and Production, Total Organic Carbon. TOC, is the amount of organic carbon present in a source rock expressed as a weight percent. It is a proxy for the total amount of organic matter present in the sediment (Ronov, ) and used as an indicator of source richness with respect to how much hydrocarbon the sediment.

There must be an organic-rich source rock to generate the oil and/or gas. 2. The source rock must have been heated sufficiently to yield its petroleum. 3. There must be a reservoir to contain the expelled hydrocarbons. This reservoir must have porosity, to contain the oil and/or gas, and permeability, to permit fluid flow. 4.   Petroleum source rock is defined as the fine-grained sediment with sufficient amount of organic matter, which can generate and release enough hydrocarbons to form a commercial accumulation of oil or gas [ 1 ]. Source rocks are commonly shales and lime mudstones, which contain significant amount of organic matter [ 2 ]. Hydrocarbons are mined from oil sands and oil shale, and probably extracted from sedimentary methane hydrates. These reserves require distillation and upgrading to provide synthetic crude and petroleum. Oil reserves in sedimentary rocks are the source of hydrocarbons for the power, shipping and petrochemical industries.   SOURCE ROCK IDENTIFICATION Effective source rock must have three features: Quantity of organic matter Quality capable of yielding moveable hydrocarbons Thermal maturity DETERMINING SOURCE ROCK POTENTIAL The quantity of organic matter is commonly assessed by a measure of the total organic carbon (TOC by weight %) contained in a rock.
