The quantitative determination of atomic hydrogen concentrations cn in the vicinity of hot filaments is performed with two-photon laser-induced fluorescence. The measurements yield atomic hydrogen concentration profiles up to 28 mm from the filament surface with a spatial resolution of about 0.5 mm. The nonequilibrium nature of the hydrogen dissociation on the filament surface results in a satu...

Accurate estimation of capillary pressure and relative permeability curves are very important for evaluating hydrocarbon recovery processes. Also, resistivity index data are important in evaluating fluid distributions in reservoirs during these processes. All these parameters are path dependent i.e. different in drainage and imbibition processes, commonly known as hysteresis, which makes them c...

Evaluation of hydrocarbon reservoir requires classification of petrophysical properties from available dataset. However, characterization of reservoir attributes is difficult due to the nonlinear and heterogeneous nature of the subsurface physical properties. In this context, present study proposes a generalized one class classification framework based on Support Vector Data Description (SVDD) ...

Abstract Lower Miocene rift sediments of the Nukhul Formation are one prominent hydrocarbon producers in Gulf Suez basin. In this study, we focused on oil producing sandstones Abu Rudeis-Sidri Field, located east central Suez. is characterized by low amplitude seismic reflectors and represents youngest identified reflector (Lower Miocene) study area. Petrophysical assessment was carried out usi...

the simultaneous flow of oil and water in porous media is described by relative permeability curves, mainly derived from laboratory experiments. relative permeability is of paramount importance in predicting reservoir production performance and drive mechanisms and its value depends largely on the volume fraction of fluids present in the test samples. nowadays x-ray scanners are one of the most...

Quantification of membrane partition potential of drug compounds is of great pharmaceutical interest. Here, a novel approach combining liquid-state NMR diffusion measurements and fast-tumbling lipid/detergent bicelles is used to measure accurately the partition coefficient K(p) of amantadine in phospholipid bilayers. Amantadine is found to have a strong membrane partition potential, with K(p) o...

We study counter-current imbibition, where a strongly wetting phase (water) displaces non-wetting phase spontaneously under the influence of capillary forces such that the non-wetting phase moves in the opposite direction to the water. We use an approximate analytical approach to derive an expression for saturation profile when the viscosity of the non-wetting phase is non-negligible. This make...

in this study, the effect of hydrocarbon and rosin ester resins combination on the physical and mechanical properties of thermoplastic road markings were evaluated. at first, two basic thermoplastic road marking formulations based on hydrocarbon and rosin ester resins were prepared. several samples of the blends of two basic formulations for thermoplastic road marking were characterized and com...

Abstract Gamtoos Basin is an echelon sub-basin under the Outeniqua offshore of South Africa. It a complex rift-type basin with both onshore and components consists relatively simple half-grabens bounded by major fault to northeast. This study mainly focused on evaluation reservoir heterogeneity Valanginian depositional sequence. The prime objective this work generate 3D static model for better ...

Abstract The present work concerns with the geophysical assessment for sandstones of Abu Roash C and E members being potential hydrocarbon reservoirs at Gharadig Field, Western Desert, Egypt. analysis seismic data covers Field showing ENE–WSW anticline fragmented by NW–SE normal faults. presence these structures is due to dextral wrench corridor that extensively deformed north area Desert withi...
