?????? ???????? ?????? ??????? ???? ????? ????? ?????Index. décimale : 550 Sciences de la terre Résumé : Reservoirs rocks and porous medium can be of high economical interest. The porous
mediums are allocated to fluid storage and circulation. They can be under the control of diverse parameters when they are found at reservoir conditions. Involvement of clay fraction and type, filling pores, is of high contribution towards the reduction of pore volumes. It is responsible for the creation of microbarriers and occlusion for fluid accumulation and mobility. In the case study, investigation based on laboratory experiments has revealed, in that regards, that reservoir is mainly controlled by compaction in addition to the type and fraction of simulated cement. It has been found that impact on petrophysical characteristics was own to the type of clay, beyond pressure and grain texture type. Kaolinite clay mineral type was the less harmful with regard to the permeability and porosity in comparison to illite and mainly bentonite. However, in the presence of aqueous solution, swelling intensity was higher with bentonite mineral in comparison to kaolinite and illite.
During drainage and essentially the imbibation, impact from the wettability (soaking....) system was defined.
Results were in harmony with the imbibation rather than drainage at atmospheric conditions.
Within the diphasiques phases, imbibition supports the hydrophilic character of the bentoniteillite clay minerals, whereas the kaolinite was as hydrophobic. Thus, and regarding the reservoir, sandstone reservoirs with the presence of kaolinite are better reservoir
characteristics but hydrphobe. Reservoirs with bentonite clay fraction are less petrophysical characteristics development; even so, it is important to mention that bentonite is hydrophilic type.
The overall results reveal that sandstone with illite clay fraction is the better concerned with permeability and porosity development or preservation leading to efficient fluid circulation and recovery.

Langues : Français (fre) Tags : HMDSO Polyimide traitement de surface mouillabilité super-hydrophobie nanopoudre PECVD RCER FTIR MEB AFM surface treatment wettability super-hydrophobic nanopowder SEM ????????? ?????? ????? ????? ???????? ??????????? Index. décimale : 621 Electronique Résumé : Plasma polymerization of hexamethyldisiloxane (PPHMDSO) was used to deposit SiOxCyHz thin films on silicon and polyimide substrates, using low-frequency plasma and microwave plasma discharge at low pressure. The effects of plasma chamber pressure, oxygen rate in Ar/O2 mixture, treatment time and post-treatment on the films characteristics were studied.
The thickness, surface properties and chemical structure of the deposited thin films were analyzed using profilo-meter measurements, scanning electron microscopy (SEM), static contact angle and infrared spectroscopy (FTIR and FTIR-ATR). At low frequencies and for certain deposition parameters, nano-powders of different concentrations and sizes were
observed on the deposited thin films surface. The FTIR analysis revealed that the chemical formula of the deposited layers is close to SiOxCyHz one, with more organic character when chamber pressure and/or deposition time were increased. Water contact angle measurements show that the increase in the deposition pressure and deposition time leads to the growth on
the polyimide and silicon substrates of thin layers with super-hydrophobic surface due to the increase in the concentration of the nano-powders on the treated surfaces. Plasmas created in HMDSO vapours using a microwave frequency plasma in ECR reactor leads to the deposition of similar PPHMDSO thin layer on polyimide and silicon surfaces. A post-treatment of these
coating layers using a microwave plasma created in Ar/O2 mixtures shows that the increase of oxygen rate in this mixture and the increase in the post-treatment time induces a significant decrease of the contact angle because of a decrease in the layers roughness (revealed by AFM characterization) and mainly, because of a more surface oxidation of the thin layers (revealed by FTIR analyzes)
