Wastewater effluents from irrigation and the domestic and industrial sectors have serious impacts in deteriorating water quality in many rivers, particularly in areas under tidal influence. There is a need to develop an approach that considers the impact of human and natural causes of salinization. This study uses a multi-objective optimization–simulation model to investigate and describe the interactions of such impacts in the Shatt al-Arab River, Iraq. The developed model is able to reproduce the salinity distribution in the river given varying conditions. The salinity regime in the river varies according to different hydrological conditions and anthropogenic activities. Due to tidal effects, salinity caused by drainage water is seen to intrude further upstream into the river. The applied approach provides a way to obtain optimal solutions where both river salinity and deficit in water supply can be minimized. The approach is used for exploring the trade-off between these two objectives. 相似文献

This study was based on the results of geochemical analysis of 332 core and 10 cutting rock samples from Triassic Jurassic, Cretaceous, and Triassic age, in addition to seismic sections, logs, initial drilling results, final reports of oil wells, and previous studies. Constructing models from these data are to assess new oil reservoirs, evaluation, and development of the existing oil reservoirs and hydrocarbon potential, and suggesting petroleum systems in order to reduce exploration risk and develop simple risk assessment of oil fields in the studied area. In general, Abu-Jir fault zone divides the studied area into two petroleum provinces: Mesopotamian Foredeep Basin and Widyan Basin–Interior Platform. The Mesopotamian Fordeep basin are thick stratigraphic sequences with no exploration for oil or gas source rock intervals within the Paleozoic sequence. while the Mesozoic sequence offers the best potential. The transitional sequence of the Triassic period is expected to contain occasional fair to good quantity of oil source rock intervals. The Widyan Basin–Interior Platform is an area with possible deployment of low to moderate risk of Paleozoic play and Lower Mesozoic plays with fair Triassic and Mesozoic objectives. Oil has generated and expelled into traps in the studied area during two phases; the first is during Early Palaeogene that accumulated in traps of the Cretaceous structural deformation, while the second is during Late Neogene. 相似文献

Three exploration wells were selected near Mosul city (Az-29, Bm-15, and Kd-1) to study the palynozones and hydrocarbon generation potential of the Upper Triassic Baluti and Kurrachine Formations. This study was completed in two phases: The first was a study of palynofacies and their paleoenvironmental indications, degree of preservation, diversity of palynomorphs, and organic maturity of the rocks according to palynomorphs’ color using a refracted light microscope. More than 80 slides of organic matter were used for this study. Four palynofacies were tentatively recognized. (1) The first palynofacies is diagnostic of the Baluti Formation in the Az-29 and Kd-1 wells; (2) The second palynofacies appeared at different depths in the Kurrachine Formation in three wells. (3) The third was only found between the depths of 4,534 to 4,685 m in the well Az-29. (4) The fourth was only found between 3,500- and 3590-m depth in the well Bm-15. A distal coastal marine environment is suggested for the Baluti Formation and restricted lagoonal environment for the Kurrachine Formation. The second phase used organic geochemical analyses to confirm the suggested paleoenvironmental and hydrocarbon generation material. Three techniques were used, namely total organic carbon, pyrolysis, and pyrolysis gas chromatography, on more than 35 samples from different depths in three wells. The analyses proved that a sufficient quantity of organic matter occurs that and has suitable maturity for hydrocarbon generation potential of oil and gas. 相似文献
