Reservoir engineering is a branch of petroleum engineering, typically concerned with maximizing the economic recovery of hydrocarbons from the subsurface.
Of particular interest to reservoir engineers is generating accurate reserves estimates for use in financial reporting to the SEC and other regulatory bodies. Other job responsibilities include numerical reservoir modeling, production forecasting, well testing, well drilling and workover planning, economic modeling, and PVT analysis of reservoir fluids.
Reservoir engineers also play a central role in field development planning, recommending appropriate and cost effective reservoir depletion schemes such as waterflooding or gas injection to maximize hydrocarbon recovery.
Drilling engineering is a subset of petroleum engineering. It is primarily involved in the design and drilling of production and injection wells. The drilling engineer has the responsibility for the efficient penetration of the earth by a well bore, and for cementing of the steel casing from the surface to a depth usually just about the target reservoir.
The term "facilities engineering" evolved from "plant engineering" in the early 1990s as U.S. workplaces became more complex. Practitioners preferred this term because it more accurately reflected the multidisciplinary demands for specialized conditions in a wider variety of indoor environments, not merely manufacturing plants.
Today, a facilities engineer (vs. a facilities manager) typically has hands-on responsibility for the employer's electrical engineering, maintenance, environmental, health, safety, energy, controls/instrumentation, civil engineering, and HVAC needs. The need for expertise in these categories varies widely depending on whether the facility is, for example, a single-use site or a multi-use campus; whether it is an office, school, hospital, museum, processing/production plant.
Process engineering is often a synonym for chemical engineering and focuses on the design, operation and maintenance of chemical and material manufacturing processes. Process engineering and process engineers are found in a vast range of industries, such as the petrochemical, mineral processing, material, Information Technology, food and pharmaceutical and biotechnological industries. Process engineering also involves developing new processes, project engineering and troubleshooting.
Petroleum engineering refers to the subsurface engineering activities related to the production of hydrocarbons, which can be either crude oil or gas. These activities are deemed to fall within the upstream sector of the oil and gas industry which are the activities of finding and producing hydrocarbons prior to the point of refining or distribution to a market, which is referred to as the downstream sector. Petroleum Geology and Petroleum Engineering are the two main subsurface disciplines within the oil and gas industry, which focus on maximising economic recovery of hydrocarbons from subsurface reservoirs. Petroleum Geology focuses on provision of a static description of the hydrocarbon reservoir rock, whilst 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. The combined efforts of Geologists and Petroleum Engineers throughout the life of a hydrocarbon accumulation determine the way in which a reservoir is developed and depleted, and usually they have the highest impact on field economics. Petroleum Engineering requires a good knowledge of many other related disciplines, such as Geophysics, Petroleum Geology, Formation Evaluation (well logging), Drilling, Economics, Reservoir Simulation, Well Engineering, Artificial Lift Systems, and Oil & Gas Facilities Engineering.
A petroleum geologist is an occupation that involves all aspects of oil discovery and production. Petroleum geologists are usually linked to the actual discovery of oil and the identification of possible oil deposits or leads. It can be a very labor intensive task involving several different fields of science and elaborate machinery.
Petroleum geologists look at the structural and sedimentary aspects of the stratum|strata to identify possible oil traps. Petroleum geologists make the decision on where the location of drilling will occur. This is done by locating a sedimentary basin. Petroleum geologists determine the well?s integrity with seven main aspects according orthodox view of petroleum exploration:
Source- The presence of Hydrocarbons in the reservoir.
Reservoir- The porous medium that contains the Hydrocarbons.
Seal- The rock unit that inhibits the oil from escaping the seal.
Trap- Structural feature that impedes the escape of Hydrocarbons.
Timing- The idea that events occurred in a certain order to allow the decomposition of organic matter into Hydrocarbons.
Maturation- The alloted time for the decompostition of organics into oil.
Migration- The flow of the (less dense) oil up the reservoir to the trap.
These seven key aspects allow the Petroleum geologist to obtain a 1-dimensional idea of the subsurface.
Some other data may be obtained via Geophysical methods. Geophysical logs show the seismology data of elastic waves, mainly seismic reflection. This allows a 3-dimensional look of the trap, and source rock. More data may be obtained from the mudlogger, who analyzes the drill cuttings and the rock formation thicknesses.
Petrophysicist job is to determine the potential quality and performance of a petroleum resource by estimating
how much hydrocarbon is present and whether it can be produced economically.

A Geophysicist must have a strong science background, a curious mind, and a fascination with natural phenomena to succeed. Geophysicists measure, examine, and explore the physical properties of earth, from below the ground to the atmosphere, from the depths of the ocean to the tops of volcanoes. Daily duties include studying readouts of measurement equipment, examining natural phenomena (such as tidal waves and electromagnetic fields), and writing reports which correlate the two
