Processes for adding a chemical composition to a produced water mixture upstream of a pad related to a well to be fracked are described. The added chemical composition comprises a drag reducing agent, or a biocide, or a scale inhibitor, or any combination thereof. The produced water mixture comprising the added chemical composition may then be transferred in a pipeline to the well to be fracked.

Processes for chemical dosing prior to the pad

A method for isolating a wet shoe sub in a horizontal section of a wellbore may include inserting a wireline tool assembly to the horizontal section of the wellbore, where the wireline tool assembly includes a wireline conveyed casing test tool. The method may also include releasing the wireline conveyed casing test tool from a remainder of the wireline tool assembly within the horizontal section of the wellbore. The method may further include perforating, using a gun string and after confirming that the wireline conveyed casing test tool is lodged against a seat of the wet shoe sub to create a seal with the seat of the wet shoe sub, a portion of the horizontal section of the wellbore upstream from the wet shoe sub after the wireline conveyed casing test tool is lodged against the seat of the wet shoe sub.
