Preliminary analyses of synthetic carbonate plugs: consolidation, petrophysical and wettability properties
نویسندگان
چکیده
Synthetic plugs are available to understand oilfield properties and the behavior of oil in reservoirs where natural cannot be extracted. Specifically, cases it is necessary reproduce representative mineralogical petrophysical characteristics from carbonate reservoirs, evident that there a lack publications focusing on synthetic plug construction. In this work, methodology construct proposed using disintegrated rock with controlled particle size, mixed different weight fraction, uniaxial compaction load force velocity, pH, temperature, bonding materials. Preliminary analysis consolidation (basic by water immersion test), wettability (contact angle measurements) (nitrogen expansion porosimetry measurements theoretical porosity calculation) reported study determine which composition samples provides similar compared expected for rocks reservoirs. Two compositions recommended samples: Composition 1 total quantity 100 g base material (50% w/w <20 μm, 50% 20–74 μm) + 5% amide wax (relative material) 6% pH 3 hydrochloric acid solution; 2 150–300 300–600 solution. addition compositions, follow procedure based (200 kN) velocity (25 mm/min) sample’s drying temperature °C h aiming obtain samples. These preliminary results will guide further dedicated deeply understanding these enhance construction more

Pore-scale Characterization of Carbonate Rock Heterogeneity and Prediction of Petrophysical Properties
Carbonate reservoirs, accounting for majority of the world’s hydrocarbon reserves, are well known for their heterogeneity and multiscale pore characteristics. The pore sizes in carbonate rock can vary over orders of magnitudes, the geometry and topology parameters of pores at different scales have a great impact on flow properties. A relatively simple way to integrate a set of digital pore spac...
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
