He is vice-rector of the UPPA in charge of innovation.

Viscoelastic analysis by a dynamic surface force apparatus of adsorbed polymers on inorganic substrates

Water solutions of high molecular weight polymerare usually used for oil recovery applications. These viscoelastic fluids exhibit an importantinterfacial slip which dominates their rheological properties at sub-micron scales. The understandingof all phenomenons when these fluids are confined is necessary to account for the behaviors observed during their flow withinnanoporeux mediums, such as oil tanks walls. To estimate the rheological behaviour of polymers at nanoscale, we will present experimental data obtained with nano-indentation technics used as nano-rheometer, exploring the terminal and plateau relaxation modes by frequency sweep at different thicknesses. Samples are either drops of model homopolymer melts(1, 3)confined within the gap as well as examples on polyacrylamide used for oil recovery (3). An important result concerns the variation of the zero-shear viscosity and the relaxation time in the terminal domain: one can demonstrate that the viscosity is not really affected by the confinement whereas the time is largely increased.

The petrochemical industry is one of the most efficient branches of international business. It has been pushed forward on the world economic scene with a significant development momentum through the strong short-term profitability of its infrastructures. Modern petrochemical production, the products of which are new materials, many of which have unique properties. Working closely with the oil and gas industry, the petrochemical industry provides excellent examples of the rational use of hydrocarbon resources, production of high levels of added value.

The gas chemical industry is part of the petrochemical industry. It arose due to the expansion of the raw material base of oil and gas chemistry, when they began to use natural gas as raw materials, as well as products of processing of natural and associated petroleum gas (ethane, propane, butanes, gas condensate fractions). As already noted, now the formation of these industries is under strong mutual influence, so we can talk about the emergence of a complex field of oil and gas chemistry.

The present study aims to evaluate, discriminate and delineate the geological and petrophysical situation of Oligocene reservoir wells at Salamat-1 and Atoll-1 in North Damietta offshore concession in the Mediterranean Sea. It deals with a combined interpretation of the core analysis (density, porosity, permeability and mercury injection capillary pressure ‘MICP’) and petrography data (thin sections, SEM and XRD) as well as well log (gamma ray, density, neutron, MSFL, shallow and deep resistivity, FMI and MDT logs) and the subsurface geologic data, as well as some available seismicsections to clarify the geological and the petrophysical characterization of the Oligocene unconventional tight sandstone gas reservoir, Salamat structure, North Damietta offshore, Mediterranean Sea, Egypt.

Petrophysically, the studied sandstone core samples can be summed up into two reservoir rock types, where poor reservoir quality is assigned to one group while the other is characterized by tight reservoir properties. These two RRTs are discriminated into four microfacies, arenites and wackes microfacies. Filling the pore spaces with detrital clays are the most important reservoir quality-reducing factors.

The seismic data indicates that the studied area is composed of Rupelian-Chattian multi-channel system located off shore with many sand channels distributed in the area. The Lower and Upper Chattian sand channels comprise the most important reservoir bodies in Atoll-1 well to the northeast of the study are gas-bearing bodies, whereas the Rupelian sand channels to the northwest at Salamat-1 well are the most important gas-bearing channels.

Integration between the available core and well log data indicated that the best storage and flow capacity are assigned to the other water-bearing sand channels rather the gas-bearing channels in both Salamat-1 and Atoll-1 wells.
