-
Aspect 2: Welding or Screwing the Casing
As soon as the casing is lowered into the wellbore, the sections are welded or screwed collectively. Welding is the commonest technique of becoming a member of the casing sections. Nonetheless, screwing the sections collectively can be an choice.
-
Aspect 3: Grouting the Casing
As soon as the casing is put in, it’s grouted. Grouting is a means of filling the house between the casing and the wellbore with a cement-based materials. Grouting helps to stop water from leaking into the properly from the encompassing soil or rock.
-
Aspect 4: Disinfecting the Casing
As soon as the casing is grouted, it’s disinfected. Disinfection is essential to stop micro organism from coming into the properly water. Chlorine is the commonest disinfectant used for wells.
The set up of the casing is a posh and essential course of. It is very important be certain that the casing is correctly put in to stop the properly from collapsing and to guard the groundwater from contamination. By following the steps outlined above, you possibly can be certain that your properly is correctly cased.
