Isatin, an extract from Strobilanthes cusia (Nees) Kuntze, was the base for synthesizing derivatives that were screened for antibacterial activity against oilfield water-borne bacteria. The bacterial groups are sulfate reducing, iron and total. The derivatives were characterized by spectrums and they showed good to moderate activity against sulfate reducing bacteria.

dezful embayment contains several potential source rocks deposited in tectonically active environments. existence of various source rocks with different geological ages makes this area one of the most prolific regions throughout the middle east. the pabdeh formation (lower paleocene-eocene), the gurpi formation (santonian-masstrichtian), the kazhdumi formation (albian) and the gadvan formation ...

Oil field is a very important non-renewable resource in China, which plays role economic strategy. In the process of oil development, water flooding technology can effectively improve production quality, provide strong technical support for our exploitation, and help to promote sustainable development enterprises. However, there are many influencing factors exploitation oilfield, so workers nee...

Dezful embayment contains several potential source rocks deposited in tectonically active environments. Existence of various source rocks with different geological ages makes this area one of the most prolific regions throughout the Middle East. The Pabdeh Formation (Lower Paleocene-Eocene), the Gurpi Formation (Santonian-Masstrichtian), the Kazhdumi Formation (Albian) and the Gadvan Formation ...

treated sea water is the most significant source of water and surfactant floods. the various chemicals employed in treatment plants should be compatible with surfactant systems. based on surface tension experiments, the activity of these chemicals is examined over a wide range of concentrations in different solutions, including distillated water, sea water by using three types of surfactant mix...

In the future, there will be more and abandoned oil-gas wells with exploitation of onshore oilfield resources. However, large height difference in can used as building blocks for gravity power generation, thus maximizing economic value wells. this study, a scheme generation by virtue spud-in casing depth is proposed, model based on established. The parameters benefits energy storage are calcula...

The the Middle Cretaceous-Lower Miocene petroleum system of the Kupal oil field, located in the Dezful Embayment has been studied. The Kazhdumi and Pabdeh are main source rocks, the Sarvak, Ilam and Asmari formations are reservoir and the Gachsaran formation is the seal rock. According to geochemical analysis the Kazhdumi and Pabdeh contributed to oil production and feeding the Asmari and Bange...

The Dorood oilfield is located offshore in the northern part of the Persian Gulf. It partly underlies the Kharg Island. The Neocomian Fahliyan Formation represents the high-quality reservoir in the oilfield. It includes five carbonate members: The Manifa, Middle and Upper Yamama, Khami and Lower Ratawi. The Fahliyan Formation in the studied well attains a thickness of 378.1 m and mainly consist...
