Abstract: The present invention relates generally to processes for adding a chemical composition to a produced water mixture upstream of a pad related to a well to be fracked. 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. This offers a number of advantages that may include, for example, reducing the footprint at the pad, improved efficacy of biocide, reduced time to transfer produced water, and/or reduced pumping time during the fracking.

Abstract: An above ground pipe is installed at a location to transport fluid for one or more operations. A fiber optic cable is laid on the above ground pipe and temporarily attached to the above ground pipe. The fiber optic cable is laid on the above ground pipe with a sinusoidal curvature to increase contact between the fiber optic cable and the above ground pipe. Leaks along the above ground pipe are detected using measurements from the fiber optic cable. The fiber optic cable is removed from the above ground pipe for re-use at a different location.
