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 also be an choice.
-
Aspect 3: Grouting the Casing
As soon as the casing is put in, it’s grouted. Grouting is a strategy of filling the area between the casing and the wellbore with a cement-based materials. Grouting helps to forestall water from leaking into the nicely from the encircling soil or rock.
-
Aspect 4: Disinfecting the Casing
As soon as the casing is grouted, it’s disinfected. Disinfection is essential to forestall micro organism from coming into the nicely water. Chlorine is the commonest disinfectant used for wells.
The set up of the casing is a fancy and essential course of. You will need to make sure that the casing is correctly put in to forestall the nicely from collapsing and to guard the groundwater from contamination. By following the steps outlined above, you may make sure that your nicely is correctly cased.
