Source rocks are one of the necessary elements of a working petroleum system. They are organic-rich sediments that may have been deposited in a variety of environments including deep water marine, lacustrine and deltaic.

Source rocks are a specific type of sedimentary rock that plays a critical role in the formation of hydrocarbons, including oil and natural gas. These rocks are characterized by a high content of organic matter, primarily derived from the remains of …

Nov 29, 2018 · The USGS Gulf Coast Source Rock Database (GCSRD) is an online repository for all publicly available source rock data (outcrop and subsurface) from the states of Florida, Georgia, Alabama, Mississippi, Louisiana, Arkansas, and Texas.

The petroleum system map in Figure 8 shows the pod of active source rock and the oil and gas accumulations that were charged by this same pod of active source rock; all are within the geographic or known extent of the system.

Sep 15, 2021 · Source Rock is the rock where petroleum formed. Source rocks are sedimentary rocks and typically shales (90%). The source rock was form along with deposition of the organic matter; thus, organic matter was abundant at the early age of a source rock.

Feb 9, 2022 · To determine the kerogen type present in a source rock, plot the hydrogen and oxygen indices on a modified Van Krevlen diagram (Figure 1). Use the HI/OI technique only to determine source rock quality (kerogen type) of immature rocks.

We have used a calibrated rock-physics model to indicate that Vshale and porosity data can be used to predict the P- and S-wave velocities and the density in wells over large sedimen-tary sections, including a source rock of variable maturity.

Jan 4, 2018 · The evaluation of a rocks past, present, and future potential to generate hydrocarbons by quantifying the elements and processes that control the evolution of an effective source rock in the context of petroleum exploration and exploitation.

Diagrams showing the TOC content and maturity of the candidate source rock. (a) Bar graph showing the variation of TOC content in the samples analysed. (b) Cross-plot showing the variation of...

Feb 4, 2022 · A source rock is a rock that is capable of generating or that has generated movable quantities of hydrocarbons. The first factor to be assessed in an exploration play in an area yet to be drilled is whether a source rock is present.
