... powder, fiber and granules had density of 1.24 g/cc. Degradation Behavior of PLA Degradation behavior of PLA evaluated at 90 °C in 3% NaCl brine is shown in Figure 3 . It can be seen that in initial neutral pH, complete degradation of PLA takes place in 24 days at 90 °C. The rate of degradation...

.... This challenging problem will be more severe if the wells are located in offshore environment, therefore finding the cause of tubing deterioration is a challenging. Field X, which has been in production for 30 years, cannot avoid the possibility of tubular thinning and deformation. The degradation is slowly...

... using a computational model that represents accurately the production system of interest. Since VFM systems mostly rely on pressure and temperature measurements, it is important to understand how accuracy and degradation of sensors influence the VFM flowrate estimates. In this work, a VFM system...

... can be considered as healable polymer systems, since unlike conventional polymer they disassemble and re-assemble when exposed to high temperature and stress conditions. In such conditions, conventional polymers generally undergo degradation. Additionally, through molecular scission processes SMA...

... on selected inspection windows to determine the severity. Thickness measurement for the worst CUI grade items was also performed in the end of idle period to find out the effect of CUI degradation to integrity of material. The evaluation reveals that about 21 percents of all inspected pipings and equipment...

Paper Number: SPE-176460-MS
... Abstract Polymer flooding in high-temperature reservoirs generally shows rather poor performance since the injected polymer suffers from severe thermal degradation which leads to ineffective in-situ sweep efficiency. Due to the absence of accurate viscosity description, simulation results...

... provides environmentally safe polymer degradation without causing damage to the formation or tubular goods. Polymer specific systems have been developed for removal of damage caused by polymers such as cellulose, guar, and starch. The treatments can be applied over a wide range of downhole conditions...
