The precursors of Mg-Al hydrotalcite (Mg/Al-LDHs-NO3) were prepared by low saturation coprecipitation method (constant pH method). In addition, alsine-intercalated magnesium-aluminum (LDHs-Ala) was synthesized pH) and nucleation/crystallization isolation methods when the value higher than isoelectric point alanine. release properties alanine intercalated hydrotalc in simulated gastric fluid (hy...

A new algorithm is presented for simulating volume-controlled invasion of a non-wetting phase into voxel images. This method complementary to the traditional morphological image opening which mimics pressure-based invasion. key advantage volume-based approach that fluid configuration at any saturation between 0 and 1 can obtained rather than irregularly widely spaced steps by methods. Because i...

An investigation was performed to measure sloshing motion and damping during harmonic forced vertical of a rectangular tank containing fluid, with particular focus on the amplitude dependent transition between lateral turbulent, slamming. Qualitative quantitative explanations are provided for saturation point dissipation effects, together metrics distinguish different regimes, ballistic-harmoni...

Abstract The static bulk modulus of unconsolidated sands is essential for predicting the in situ effective pressure to reduce drilling risks deepwater reservoirs; however, dynamic often more broadly available from seismic or well logging data. Therefore, it tempting investigate relationship between and moduli. We perform a series ultrasonic velocity measurements on 21 reservoir Gulf Mexico (GoM...

cally, water is assumed to be immobile at the residualwater saturation. In the petroleum industry, the residAt many contaminated sites, nonaqueous phase liquids (NAPLs) ual-water saturation is also called the irreducible-water persist in the vadose zone for long periods of time. This occurs because the permeability of the NAPL becomes negligible at some saturation saturation. This terminology h...

This paper discusses a new nuclear magnetic resonance (NMR) method that can provide wettability, saturation, and oil viscosity values in rocks partially saturated with oil and brine. The method takes advantage of two new technological advances in NMR well logging — the MRF Magnetic Resonance Fluid Characterization Method and NMR “diffusion-editing” (DE) pulse sequences. We discuss the principle...
