... of State (EOS) model was performed and validated with laboratory data. The solid precipitation analysis was conducted to observe and predict any similar issues from both bottomhole and surface samples. The prediction of solid precipitation in all reservoirs was conducted through thermodynamic modeling...

... resulted in a more cost-effective solution. The treatment consisted of HCl and mud acid only, which is an uncommon practice for a typical acid matrix treatment for clastic formation. Without additives, solid precipitations are a major concern as it can cause further damage to the near wellbore region...

During CO 2 injection into depleted gas reservoirs, it is anticipated that there will be mineral dissolution or precipitation effects due to geochemical reactions that alter the rock porosity...

... chromatography analysis of the samples, as precipitation from KHI product-A. At that time KHI injection was halted and reverted back to MEG using two regeneration trains, one contaminated, and other non-contaminated. The cause of such precipitation was identified as contact of the neat KHI chemical...

... shaping and precipitation at various locations inside the system, the advised method can quantitatively foresee the dangerous position and intensity of hydrate obstruction. The time from the start of production to the dramatic change of pressure drop brought about by the deposition of hydrate attached...

... Abstract Asphaltenes in the production process often cause significant damage to oil production operation through the continuous growth process (precipitation followed by aggregation and finally deposition) of their particles. To mitigate the asphaltene-induced problems, Asphaltene Inhibitor...

... Abstract Precipitation and deposition of hydrocarbon solids such as asphaltenes and wax are some of the major challenges facing the oil and gas processing and transportation industry. Deep-water, high pressure and high temperature (HPHT) environment are currently being explored for meeting...

... The first step for this test was to investigate the compatibility of two alkalis and sodium acrylate with synthetic hard brine. In the second step, acrylic acid to sodium metaborate interaction tests was performed to find an optimum ratio for preventing any precipitation. In the final step...

.... In this work, two enzymatic systems were evaluated: old a-amylase system and new structurally reinforced a-Helix system. The old enzyme was found to form a potentially damaging precipitate at reservoir temperature above 100oC. The degree of this damage was assessed using size-matching technique and core-flood...

..., and precipitation processes, we first developed a streamline-based model assuming incompressible and immiscible two-phase flow of CO 2 and water. Procedures of the common streamline method were followed. Along streamlines, 1-dimensional flow equations were solved for CO 2 in its own phase and CO 2 concentration...
