چکیده

salman and resalat oilfields are such marine oilfields that are in vicinity of each other. there is resalat oilfield in distance about 80-90 kilometers from lavan island in persian gulf. this oilfield is located in 25 kilometer southwest in reshat oilfield. salman oilfield is located in vicinity of water border line of united arab emirate in 140 kilometers of south of lavan island. this oilfield is remarkable because of its reservoir value and also it is common between iran and united arab emirate. surmeh reservoir structure is an oily reservoir that it’s common between two oilfields. in order to study of geochemistry features, oil samples of salman and resalat’s oilfield analyzed by using usual geochemistry techniques such sara test, gaseous chromatography techniques (gc) and gaseous chromatography – mass spectrograph (gc-ms). according to results, including of distribution of values in formed hydrocarbon cuttings of these oils, study of biomarkers in terpans and tabloid steranes group from saturation cutting, we can say that hydrocarbons in surmeh reservoir in resalat and salman oilfield show paraffinic oil features and kerogen type ii that all of these indicate organic material with marine origin. the geochemical study of parent rock in these oilfields shows that the active oil system comes from late cretaceous and the reservoirs were fed from common hydrocarbon system. the gathering hydrocarbons at mentioned oilfields, also, were produced by carbonate source rock with a little shale in revival conditions. the parameters of mature biomarkers in these oilfields show that in border of two oil-forming windows it gathered the suitable organic material for producing good oil. thus, according to analyses, there is integration between surmeh reservoir in resalat and salman oilfield and their oil come from one resource.

The Evaluation of Reservoir Quality of Sarvak Formation in One of Oil Fields of the Persian Gulf

Sarvak formation, with the middle cretaceous (Cenomanian) age, is one of the stratigraphic units of the Bangestan group in the southern Iran. The carbonate rocks of this formation form the reservoir rock in the study field. Generally, Sarvak formation is subdivided into three members including Mishrif, Khatiyah, and Maddud in the Persian Gulf, and the average thickness of the reservoir unit (i....

Effect of polysilicon nanoparticles on enhanced oil recovery in Iranian oil reservoir

Recovery Factor is an important parameter in determining commercial viability of the oil Reservoirs. Wettability is a major factor that affects oil Recovery. Therefore, changing rock wettability may enhance oil recovery. In this paper, the effect of polysilicon nanoparticles on wettability change of Iranian carbonate reservoir is investigated. To assess this, hydrophilic changes of carbonate ro...
