Among these, hydrogen...

.... The chemical reaction highlighting the degradation of PLA is shown in Figure 2 ( Jin, Wan, & Liu, 2017 ). Abstract Fluid loss during workover of subhydrostatic wells is a major concern while servicing the wells in brown/matured fields. Excessive fluid loss results in delayed well activation...

.... 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...

.... This is particularly true for downhole sensors. Such conditions cause mechanical degradation which increases the measurement noise and drift. ( Kikani et al. 1997 ). As such, one of the questions addressed in this paper is how the sensor degradation impacts the VFM flowrate estimates. A somewhat similar question...

... 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...

... 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...

... Polymeric damage to proppant pack and formation permeability can significantly decrease well production. The damage, in many cases, is due to insufficient degradation of drilling, completion, or stimulation fluids and the dynamically formed filter cake on the formation face. 1 – 3...
