Ghawar has been the world’s largest oil field for decades, a distinction that brings with it the ability to control, to some extent, the world’s supply of oil. I looked at the coordinates given for the field (27°28′12″N, 48°31′12″E) on Google Maps, and they seem to be too far north. Freeman, San Francisco, 1954, Mitchell, J.C., Lehmann, P.J., Cantrell, D.L., Al-Jallal, I.A. Aramco rarely releases data about its oil fields; when it has, the reports have always been wildly disproportionate to the facts. Data on Ghawar reported in the past issues of Oil & Gas Journal indicate that when Ghawar came on stream in 1951 it produced 126,000 bopd but production steadily rose with a major boost soon after the 1973 oil shock so that the field’s 1975 output was 4.2 MMbopd; this reached a maximum production of 5.7 MMbopd in 1981. well), USA Natural provided by Aramco in the bond prospectus, we estimate Part of what is missing from this discussion is how much of the This peripheral waterflood project began in the early sixties in the northern parts of the field. Interparticle porosity is abundant in the Arab-D reservoir in the Ghawar Field and moldic porosity is common as well.

NES Global Talent is proud to announce the strategic alignment between ourselves and the Fircroft Group to create NES Fircroft, one of the leading human capital solutions businesses for engineering and technical talent globally. In January 2017 it was announced that Saudi Aramco was hiring auditors to look into their oil reserves as part of the IPO expected in 2018 which looks to sell less that 5% of the company. Named Ghawar from the name that the Bedouin tribes used for the area, the 5,300km2 field is divided into six areas: Fazran, Ain Dar, Shedgum, Uthmaniyah, Haradh and Hawiyah with the main reservoir of the field comprises of Arab-D Jurassic organic rich mudstones, lying 2,100m beneath the surface. At Ghawar at the Site of the Different Discovery Wells, Saudi Aramco's view of the Ghawar's reserve potential and its The field also contains 90 trillion cubic feet of natural gas reserves at the beginning of 2013. This remarkable production history is because of the enormous size of the Arab-D reservoir in the Ghawar Field. http://www.tradearabia.com/news/OGN_177826.html, http://www.geoexpro.com/articles/2010/04/the-king-of-giant-fields, http://www.hydrocarbons-technology.com/projects/ghawar-oil-field/, http://www.epmag.com/ghawar-arabian-granddaddy-775846#p=full, http://uk.reuters.com/article/us-saudi-aramco-ipo-idUKKBN15A27X, http://www.reuters.com/article/us-aramco-gas-idUSKBN1541PK. Agency Copyright © 2020 NES Fircroft. On top of Ghawar, which was found in 1948 by an American geologist, Saudi Arabia relies heavily on two other mega-fields: Khurais, which was discovered in 1957, and can pump 1.45 million barrels a day, and Safaniyah, found in 1951 and still today the world’s largest offshore oil field with capacity of 1.3 million barrels a day. directly analogous fields, the potential for achieving such recovery oil and gas producers and service companies, International and National Overview Map of the Saudi Arabian Oil and Gas Industry, More Detailed View of the Location of the Ghawar Field, Ghawar Structure Map on the Top of the Jurrasic Arab D In the uppermost part of the Arab-D are occasional zones that contain more than 10% of a stromatoporoid sponge known as cladocoropsis. All rights reserved. Our estimate for OOIP is approximately 170 billion barrels, indicating By the end of 2012, the field had more than 3,000 injector and oil producer wells, and in 2015 it was reported that Saudi Aramco started injecting carbon dioxide to boost extraction rates and do its part in reducing carbon emissions. According to the Energy Information Administration, the single field has more reserves than all but 7 countries. The Ghawar Oil Field is by far the largest conventional oil field in the world and accounts for more than half of the cumulative oil production of Saudi Arabia. The oil-water contact at Ghawar dips to the northeast, dipping more than 660 feet between the southwest end of Haradh and the Fazran area. A map of the Ghawar structure at Arab-D level appears below. Energy Agencies, International Energy It is composed of skeletal grainstones and packstones with ooid grainstones locally common in the upper Arab-D. Along about the time this issue reaches its readers the field will be producing on the order of five million barrels of oil a day. The anhydrite in the Upper Arab-D forms the seal for the 1,300-foot oil column in Ghawar. It is composed of sabkha evaporites and subaqueous evaporites with thin carbonate interbeds that can be traced for hundreds of kilometers. Where this facies is dolomitized, the relatively fine-grained matrix is replaced by dolomite and the cladocoropsis is leached, causing a phenomenon described by reservoir engineers as super-permeability. Intercrystal pores are common in dolomites and microporosity is abundant in both limestone and dolomite lithologies. Located in the Easter Province of Saudi Arabia, around 200km east of Riyadh, it accounts for more than half of Saudi Arabia’s oil production and in 2009 it was estimated to account for 6.25% of the world’s total oil … and Khurais in Saudi Arabia. perforating depths, pressures, and volumes by stage for a 50 stage At the time that this record was achieved, the southern areas of Hawiyah and Haradh had not yet been fully developed. Oil Market Report, Department of Trade and The field continues to undergo development for productivity increases and extended life, including Maximum Reservoir Contact (MRC) wells with down-hole Interval Control Valves (ICVs). If there is one thing that is more impressive than Ghawar's size, however, it is its productivity. Saudi Aramco has plans to nearly double their current gas production to 23 billion standard cubic feet a day in the next decade. the EUR for oil from Ghawar will be approximately 128 billion barrels. remaining estimated recovery will require some type of EOR? (Godagast 01:22, 6 April 2011 (UTC)) I have given Ghawar field coordinates corresponding to the oasis of Al-Ahsa, which in turn corresponds with the Uthmaniyah production area of the field. These crests existed at the time of Arab-D deposition and the reservoir quality is best in the crestal areas. areas of Ghawar, The following panel contains an illustrative, interactive 3D The anhydrite thickens to the south at the expense of the reservoir zones; the combined thickness remains relatively constant. Peak oil advocates long noted that the natural decline in Ghawar was thought to be 8%, meaning that all else being equal, production would drop 400 tb/d from the 5 … in the not too distant future. Link It is Callovian and Oxfordian in age and reaches a thickness of more than 300 feet in the basinal area between the Ghawar and Khurais Fields. The Ghawar Field was discovered in 1948. Ghawar is the largest known oil field, not only in Aramco's concession area, but in the world. productive shale play, US Production began in 1951 and it is said that the peak production from the field was in 1981 when it was consistently producing 5.7m barrels per day – the highest oil production rate from a single field in history. It’s hard to say if the world be able to depend on Saudi’s Ghawar oil field in the future. In 2013 it was estimated to have 70bn barrels remaining. Link to Energy Consulting Group webpage with Although it is a single field, it is divided into six areas. formation, the Main, Regional Cross Section, including the Jurrasic Interval in which Deep Utica Dry Gas- Emergence of a "super" Basin:  King of the Oil Shales (includes detailed frack history of to full screen version the rotatable, zoomable 3D oil and gas map of Ghawar. The three southern areas extend across both crests. Also, when we compare Ghawar to The Ghawar Oil Field is by far the largest conventional oil field in the world and accounts for more than half of the cumulative oil production of Saudi Arabia. The Ghawar structure consists of two subparallel, north-south trending structural crests, separated by a saddle.
