-
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 most typical methodology of becoming a member of the casing sections. Nevertheless, screwing the sections collectively can also be an choice.
-
Aspect 3: Grouting the Casing
As soon as the casing is put in, it’s grouted. Grouting is a technique of filling the area between the casing and the wellbore with a cement-based materials. Grouting helps to stop water from leaking into the effectively from the encompassing soil or rock.
-
Aspect 4: Disinfecting the Casing
As soon as the casing is grouted, it’s disinfected. Disinfection is necessary to stop micro organism from coming into the effectively water. Chlorine is the most typical disinfectant used for wells.
The set up of the casing is a posh and necessary course of. You will need to be certain that the casing is correctly put in to stop the effectively from collapsing and to guard the groundwater from contamination. By following the steps outlined above, you’ll be able to be certain that your effectively is correctly cased.
