The chapter also covers some of the elastomers and plastics that form seals within completion components.
In this situation, sand particles migrate from the formation matrix toward the wellbore and consequently affect permeability of the formation and completion components like frac-packs or gravel-packs.
Completion components have to be able to handle high temperatures and pressures and acidic environments.
Operationally, the production of sand is, in general, undesirable as it can restrict productivity, lead to erosion of the completion components, impede wellbore access, and interfere with the operation of downhole equipment.
The well was plugged up to 2620 m to avoid production of hot, potentially very acidic fluid at temperature and pressure above the rating of well completion components (Mortensen et al. 2010).
Within the Boost survey there were fewer missing items for the household component, where the interviewer carried out the short household interview on paper, than the self-completion component.
These surveys provided information about how well the group members worked together and whether this facilitated or impeded completion of the component tasks in the linkage intervention as well as the study's focal outcomes.
We demonstrate that a future study is feasible, with a robust consent rate (74%) and study component completion rate (81%) surpassing target thresholds.
If is an optimal completion, then a component C∗ of B can only contain two or more - paths if C∗ is a 2 - bracelet.
13 23 24 These factors may explain, in part, the striking reduction in readmissions associated with the completion of outpatient components in this study, which placed particular emphasis on close clinic follow-up for enrolled patients.
It also plays the role of reference datum during assembly until the completion of main components assembly.
