The vertical channels of fluid migration detection, as well as presence of anomalous zones of the "Oil and Gas deposit" type at different levels can be regarded as additional and important evidence of the predominant role of an abiotic origin of hydrocarbons in the Eastern Mediterranean.Many players reach out to us to ask help in fixing slow download speed on Steam. In separate structures large accumulations of oil and gas have been formed at the various crust horizons during deep fluid expulsions and reactivations of weakened zones in a global process of the Earth degassing. They should be considered as the most promising for a detailed study by geophysical methods and prospecting wells location. Within two anomalous zones of the "Oil & Gas" type, found near Zohr large gas field in the Mediterranean Sea (Egypt and Cyprus shelves), the vertical channels of depth fluids migration have been mapped. Based on the results of satellite data processing, preliminary recommendations on the selection of sites for prospecting wells in block on the shelf of Libya (between Pelagian and Sirte Basins) are proposed. Some obtained results of direct-prospecting methods and technologies using in separate areas of the Mediterranean Sea are given.

Moreover,~99% of the undesired CO 2 and CO gases were removed in the purification zone and a reduction of energy consumption of 77.5% was reached in the heating and cooling units of the process. Optimum production of hydrogen (87,404 MT/year) was obtained by fixing the temperatures in the reformer and the gas shift reactors (HTS & LTS) at 900 C, 500 C and 200 C respectively while maintaining a pressure of 7 atm, and a steam to carbon ratio (S/C) of 4. All the parameters were optimized to successfully run a complete process including the hydrogen production zone units (reformer reactor, high temperature gas shift reactor HTS and low temperature gas shift reactor LTS) and the purification zone units (absorber and meth-anator). In this work, we present a simulation and an optimization study of an industrial natural gas steam reforming process by using Aspen HYSYS and MATLAB software.
