(i.e., higher pore velocity, vp) from the pores as shown by Equation 10. This substantial reduction in fluid viscosity is due to the oil phase which can change viscosity in the 100 to 400 F (37-204 C) temperature range by over an order of magnitude—for high molecular weight C30 ...
Possible reason is the conformational change, which the protein undergoes upon adsorption. At bulk pH of 4.0, the BLG-laden oil/water interface is close to isoelectric state (the surface charge density is very low). Under these conditions, there is evidence for long-range steric repulsion, ...
If we include any precipitated carbonate and sulphide scale along the well in our calculations, the total carbonates and sulphides do not change from reservoir to separator. This is important for our following calculations. 3.2.2. STEP 8: run PVT at selected T and p interval In this ...
these molecules act as surfactants and come into the oil–gas interface and change the trend of IFT reduction So, the data breakpoint can be considered as the asphaltene onset point. This is why the CPA EoS provides a more accurate prediction in the second part. Table5shows the AAD% calcul...

Switching to xanthan solutions does not seem to significantly change the break-up process. Any quantitative difference with respect to the Newtonian liquid can be accounted for by a suitable value of the xanthan viscosity that depends on the flow rates. We have deduced ample variations in the ...
In addition, the oil film equivalent stiffness 𝐾𝑒Ke of the inner and outer cavities decreases with the increase in the diameter of the damping hole, and the oil film equivalent damping 𝐶𝑒Ce increases with the increase in the diameter of the damping hole, but the change in range ...
The organoleptic characteristics of virgin olive oil (VOO), together with its nutritional and health properties, have led the olive tree to be cultivated beyond the Mediterranean basin, reaching latitudes with colder climates, with minimum temperatures b
The findings of this research will eventually help the oil palm growers to have systems in place to address the abrupt droughts brought about by climate change. Future work of this research can be explored with SAR-based vegetation descriptors, e.g., Radar Vegetation Index and optical derived ...
