Today, due to the natural decline of oil exploitation, the use of methods of oil recovery, has made significant progress. However, these methods are accompanied by accumulation and deposition of mineral deposits in oil field installations. In the present study, aqueous solutions, strontium sulfate, barium sulfate, manganese sulfate and nickel sulfate are studied, in terms of EUNIQUAC model and ...

Both soil and water become contaminated by oil and oil derivatives due to accidental spills in their exploitation, transportation, processing, storing and utilization. In 2010, 3.91 billion tons of crude oil was produced (BP Statistical Review, 2011) and estimations are that annually 0.1% of produced petroleum is released into the environment (Ward et al., 2003) as a result of anthropogenic act...

Linguistic Data Consortium has recently embarked on an effort to create integrated linguistic resources and related infrastructure for language exploitation technologies within the DARPA GALE (Global Autonomous Language Exploitation) Program. GALE targets an end-to-end system consisting of three major engines: Transcription, Translation and Distillation. Multilingual speech or text from a varie...

this research presents a mathematical model for oil and gas optimal allocation to different sectors in iran using operations research techniques. sectors are residential and commercial, transportation, industries, agriculture, exports, injection to oil reservoirs and power plans as a secondary energy producer. optimal allocation of energy resources to end-uses from 2011 to 2021 has been done us...

Oil shale is a kind of unconventional energy resource with abundant reserves, but its exploitation has continuous negative impact on the environment, which hindered research and oil under international environmental consensus issues such as climate change. Therefore, more attention should be paid to problems side effect exploitation. With combination field research, literature collection, track...

With the continuous growth of economy, we are more and aware importance energy its preciousness. In production crude oil, narrow channel is best location for oil storage, underlying sand body often has resources. this paper, effect reservoir polymer flooding taken as purpose, principle technology theoretical basis, through analysis dynamic change characteristics, in order to improve adjustment ...
