Petroleum engineering is a field of engineering concerned with the activities related to the production of hydrocarbons, which can be either crude oil or natural gas. Exploration and production are deemed to fall within the upstream sector of the oil and gas industry. Exploration, by earth scientists, and petroleum engineering are the oil and gas industry's two main subsurface disciplines, which focus on maximizing economic recovery of hydrocarbons from subsurface reservoirs. Petroleum geology and geophysics focus on provision of a static description of the hydrocarbon reservoir rock, while petroleum engineering focuses on estimation of the recoverable volume of this resource using a detailed understanding of the physical behavior of oil, water and gas within porous rock at very high pressure.
Petroleum geology is the study of origin, occurrence, movement, accumulation, and exploration of hydrocarbon fuels. It refers to the specific set of geological disciplines that are applied to the search for hydrocarbons.
Kerogen is solid, insoluble organic matter in sedimentary rocks. It consists of a variety of organic materials, including dead plants, algae, and other microorganisms, that have been compressed and heated by geological processes. All the kerogen on earth is estimated to contain 1016 tons of carbon. This makes it the most abundant source of organic compounds on earth, exceeding the total organic content of living matter 10,000-fold.
Organic geochemistry is the study of the impacts and processes that organisms have had on the Earth. It is mainly concerned with the composition and mode of origin of organic matter in rocks and in bodies of water. The study of organic geochemistry is traced to the work of Alfred E. Treibs, "the father of organic geochemistry." Treibs first isolated metalloporphyrins from petroleum. This discovery established the biological origin of petroleum, which was previously poorly understood. Metalloporphyrins in general are highly stable organic compounds, and the detailed structures of the extracted derivatives made clear that they originated from chlorophyll.
The abiogenic petroleum origin hypothesis proposes that most of earth's petroleum and natural gas deposits were formed inorganically. Scientific evidence overwhelmingly supports a biogenic origin for most of the world's petroleum deposits. Mainstream theories about the formation of hydrocarbons on earth point to an origin from the decomposition of long-dead organisms, though the existence of hydrocarbons on extraterrestrial bodies like Saturn's moon Titan indicates that hydrocarbons are sometimes naturally produced by inorganic means. A historical overview of theories of the abiogenic origins of hydrocarbons has been published.
Isotope geochemistry is an aspect of geology based upon the study of natural variations in the relative abundances of isotopes of various elements. Variations in isotopic abundance are measured by isotope-ratio mass spectrometry, and can reveal information about the ages and origins of rock, air or water bodies, or processes of mixing between them.
The International Continental Scientific Drilling Program is a multinational program to further and fund geosciences in the field of continental scientific drilling. Scientific drilling is a critical tool in understanding of Earth processes and structure. It provides direct insight into Earth processes and critically tests geological models. Results obtained from drilling projects at critical sites can be applied to other areas worldwide. It is, therefore, believed that international cooperation in continental scientific drilling is an essential component for a responsible management strategy for the Earth's natural resources and environment.
Petrophysics is the study of physical and chemical rock properties and their interactions with fluids.

Sir Alexander Norman Halliday is a British geochemist and academic who is the Founding Dean Emeritus of the Columbia Climate School, and Former Director of the Earth Institute at Columbia University. He joined the Earth Institute in April 2018, after spending more than a decade at the Department of Earth Sciences at the University of Oxford, during which time he was dean of science and engineering. He is also a professor of Earth and Environmental Sciences at Columbia University.
The Deep Carbon Observatory (DCO) is a global research program designed to transform understanding of carbon's role in Earth. DCO is a community of scientists, including biologists, physicists, geoscientists and chemists, whose work crosses several traditional disciplinary lines to develop the new, integrative field of deep carbon science. To complement this research, the DCO's infrastructure includes public engagement and education, online and offline community support, innovative data management, and novel instrumentation development.
Katrina Jane Edwards was a pioneering geomicrobiologist known for her studies of organisms living below the ocean floor, specifically exploring the interactions between the microbes and their geological surroundings, and how global processes were influenced by these interactions. She spearheaded the Center for Dark Energy Biosphere Investigation (C-DEBI) project at the University of Southern California, which is ongoing. Edwards also helped organize the deep biosphere research community by heading the Fe-Oxidizing Microbial Observatory Project on Loihi Seamount, and serving on several program steering committees involving ocean drilling. Edwards taught at the Woods Hole Oceanographic Institution (WHOI) and later became a professor at the University of Southern California.[1][2]

Craig E. Manning is a professor of geology and geochemistry in the Department of Earth, Planetary, and Space Sciences at the University of California, Los Angeles, where he served as department chair between 2009 and 2012. Manning's research interests include water chemistry, thermodynamics, gas chemistry, geochemistry, igneous petrology, and metamorphic petrology.
Rajdeep Dasgupta is a professor of Earth, Environmental, and Planetary Sciences at Rice University. In his research, he studies the role of subsurface melting and magma on the origin and evolution of the Earth and other terrestrial planets.

In his research, he measures isotopes of sulfur and other elements to investigate water-rock-microbe interactions, seafloor hydrothermal systems, the deep biosphere, and global sulfur cycles.
Christopher R. Glein is an American geochemist at the Southwest Research Institute in San Antonio, TX. He studies planetary science, astrobiology, and organic geochemistry. Glein was the first to describe how Saturn's moon Enceladus is the only known body, besides Earth, that has all of the requirements necessary for life. Glein has been involved in multiple spacecraft missions, leading to significant findings about Pluto, Enceladus, and Titan. In 2017, he was recognized for Outstanding Contributions to the ESA Rosetta Mission by the European Space Agency.
Fault zone hydrogeology is the study of how brittlely deformed rocks alter fluid flows in different lithological settings, such as clastic, igneous and carbonate rocks. Fluid movements, that can be quantified as permeability, can be facilitated or impeded due to the existence of a fault zone. This is because different mechanisms that deform rocks can alter porosity and permeability within a fault zone. Fluids involved in a fault system generally are groundwater and hydrocarbons.
Peter H. Barry is an American geochemist who is an associate scientist in the marine chemistry and geochemistry department at the Woods Hole Oceanographic Institution. He uses noble gases and stable isotopes to understand the volatile history and chemical evolution of Earth, including the dynamic processes of subduction, mantle convection and surface volcanism, which control the redistribution of chemical constituents between the crust and mantle reservoirs. Barry’s main research focus has been on high-temperature geochemistry, crust-mantle interactions and the behavior of volatile fluids in the lithosphere. He also studies crustal systems, the origin of high helium deposits, including hydrocarbon formation and transport mechanisms.
