Iran Natural Asphalt
Iran Natural Asphalt or Natural Tar
Booth bitumen to oil and natural springs is an ancient record. Long, southwest Iran bitumen for fuel consumption and treating diseases were used. In ancient Egypt, the mummy of this material was used.
Natural Asphalt crude oil derivatives in the way of finding the surface (or near ground level) and the adoption of an appropriate atmosphere and drying is produced.
Natural Asphalt considering new applications, unlike the past that only the burning material was considered as a matter is considered.
Because this mineral is found in small countries and Iran is one of them had abundant reservoirs of Natural Asphalt, (but use it correctly so far do not know), so in here is trying to position geological Natural bitumen is mentioned especially in Iran ( Iran Natural Asphalt ).
Almost all major areas of the world’s oil, natural tars presence in on ground level have been discovered. Solomon Masjid oil field host one of these fields.
Based on studies in the basins of the world’s oil has been carried out, the characteristics of natural Bitumen outcrops west of the study partially in accordance with the pattern in Venezuelan in Lake area.
In the southwest of the oil layer in the area of oil and oil town homes, Iraq, oil reservoirs are created, influenced the performance and activities have been folded structure and oil level they have landed. These conditions describe conditions in the areas mentioned Venezuela and coordination are somewhat consistent.
Today marked failure and incompetence cut and thus meeting the hydrocarbon material and eventually formed natural tars continental margin of the page, is natural and normal. In such circumstances, the limit of Qasr e Shirin and Gilan West, Sevmareh, Dehloran is to be followed.
According to international and global studies conducted, the following points for evaluating hydrocarbon leak (natural tars) basins rich in diapir under pressure and saturation pressure and active thrust interesting.
– Natural Asphalt deposits in the active thrust Belts abundant and exposed them in basins of passive tectonic rare.
– Most oil reservoirs or deep basin oil bitumen outcrops do not cause.
– Abnormal in the discontinuity location and the unconformity may appear.
– Petroleum basins within the continental (dry environment) and marine basins are having more frequent.
– In terms of oil exploration, the presence of natural tars exploration in an area, to significantly reduce exploration risk and on the other hand was a natural tars active tectonic basin or study area with shallow faults, increasing the risk exploration gives.
– When the hydrocarbon material from their accumulation in the reservoir and released upward move in or near the surface, are some changes that eventually combine their chemical and physical changes. Some of these changes include:
A) lighter hydrocarbons evaporated: in the first two weeks of oil reaches the surface, its lighter hydrocarbons up to C15 loses. Then in the next months additional hydrocarbons and more evaporation to about C24 and disappear.
B) Washing the compound soluble in water: the further compound of nitrogen, sulfur and oxygen soluble, plus some of the lighter aromatic hydrocarbons, may be leached by ground water and get out of the environment.
– When the oil moves to the surface and it comes under the effect of the microbial attack is placed.
– polymerization: Some medium and large molecules in the outcome of this process and after the removal of water, carbon dioxide and hydrogen on large complex structures are formed.
– Oxidation, further compound the existing oil and sunlight they absorb oxygen and therefore, it paved the oil-rich oxygen to convert. Long-term presence in the air and sunlight, oxygen Tars can reach up to about 6 percent by weight.
– Gelatin: possible over time, some types of natural Tars gel-like structure, there are hard to take.
Outcrops of Iran Natural Asphalt
Iran Natural Asphalt in the provinces of Kermanshah (Oil City area, Gilan, West, Sweet Palace) Elam, Seymareh, Mehran, Dehloran Khuzestan (PA areas, Ramhormoz) with Gachsaran formations, rust and Asmari trap occurs. This exposed the reservoir rock and trap color Asmari have originated. Table 5-9 abnormal number of deposits is given.
Mother and source rocks in the tank Asmari Anticline Oil City and West region of Gilan, Seymareh, TZ2 organization under section ring traps that are formed during the middle Eocene, and have plenty of organic matter. Is shale, marl, and stone rich marl Bitumine on surface anticlines and around the Imam Hassan and to areas to the south east of figs – clock can be seen.
Name row storage location host rock likely quality of mineral:
1– tars (Sadeghi) 9 km northwest of Gilan West Gachsaran 91,700 tons of carbon formation 80%, sulfur 7, 0% and 9% ash
2– Gursefid (coral) 11 km north west of Gilan West Gachsaran Formation 180,000 tons 83% carbon, sulfur, 3, 1% and 4% ash
3– Seymareh 8 km east of Oil City Gachsaran formation is available on 76% of carbon, sulfur, 5, 1%, and 13%
4– Refining and helpers 20 km north west of Gillan West Gachsaran formation is available on 70% of carbon, sulfur, 5, 10% and 18% ash.
5 -Ahangaran 30 km northwest PA Gachsaran formation – in this region, salt water springs along the bitumen can be seen in summer flows.
6 -Mamatyn 40 km Ramhormoz – Izeh Gachsaran formation – in the area about 80-10 Bitumen springs can be seen.
