Example of a map used by Reservoir Engineers to determine where to drill a well. This screenshot is of a structure map generated by Contour map software for an 8500ft deep gas & Oil reservoir in the Erath field, Vermilion Parish, Erath, Louisiana. The left-to-right gap, near the top of the contour map indicates a Fault line. This fault line is between the blue/green contour lines and the purple/red/yellow contour lines. The thin red circular contour line in the middle of the map indicates the top of the oil reservoir. Because gas floats under oil, the thin red contour line marks the gas/oil contact zone.
Screenshot of an Isopach map generated by reservoir modeling software for an 8500ft deep oil reservoir 28ft thick located in the Erath field, Vermilion Parish, Erath, Louisiana. The contour interval is 2 ft between successive contour lines. Because oil floats above water, the outer red color indicates the elevation of the water/oil contact zone, which is at the bottom of thePetroleum reservoir. Inside the dark blue color is a thin red contour line which indicates the top of the oil reservoir, 22 feet above the water/oil zone. Because gas floats above oil, the thin red contour line marks the gas/oil contact zone. The five smallest circles inside the image indicate slight depressions along the roof, or oil/gas zone, of the reservoir. Oil drilling to this petroleum reservoir could use Directional drilling to accurately target the 28 ft thick space, 8,500ft underground.
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. 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,reservoir engineering, well engineering, artificial lift systems, completions and oil and gas facilities engineering.
Overview [edit]
The profession got its start in 1914 within the American Institute of Mining, Metallurgical and Petroleum Engineers (AIME). The first Petroleum Engineering degree was conferred in 1915 by the University of Pittsburgh.[1] Since then, the profession has evolved to solve increasingly difficult situations, as much of the "low hanging fruit" of the world's oil fields have been found and depleted. Improvements in computer modeling, materials and the application of statistics, probability analysis, and new technologies like horizontal drilling and enhanced oil recovery, have drastically improved the toolbox of the petroleum engineer in recent decades. Deep-water, arctic and desert conditions are usually contended with. High Temperature and High Pressure (HTHP) environments have become increasingly commonplace in operations and require the petroleum engineer to be savvy in topics as wide ranging as thermo-hydraulics, geomechanics, and intelligent systems. The Society of Petroleum Engineers (SPE) is the largest professional society for petroleum engineers and publishes much information concerning the industry. Petroleum engineering education is available at 17 universities in the United States and many more throughout the world - primarily in oil producing regions - and some oil companies have considerable in-house petroleum engineering training classes. Petroleum engineering has historically been one of the highest paid engineering disciplines, although there is a tendency for mass layoffs when oil prices decline. In a June 4th, 2007 article, Forbes.com reported that petroleum engineering was the 24th best paying job in the United States.[2] The 2010 National Association of Colleges and Employers survey showed petroleum engineers as the highest paid 2010 graduates at an average $125,220 annual salary.[3] For individuals with experience, salaries can go from $170,000 to $260,000 annually. They make an average of $112,000 a year and about $53.75 per hour.
Types [edit]
Petroleum engineers divide themselves into several types:
Reservoir engineers work to optimize production of oil and gas via proper well placement, production rates, and enhanced oil recovery techniques.
Drilling engineers manage the technical aspects of drilling exploratory, production and injection wells.
Production engineers, including subsurface engineers, manage the interface between the reservoir and the well, including perforations, sand control, downhole flow control, and downhole monitoring equipment; evaluate artificial lift methods; and also select surface equipment that separates the produced fluids (oil, natural gas, and water).
