Today, friction reducer, scale inhibitor, and biocide treatments are applied at the blender mostly out of convenience. This process severely limits the ability to effectively treat all water because chemical treatments are halted during the acid breakdown and flush phases. The failure to treat water at the beginning and ending of each frac stage results in an incomplete bacteria kill and elevated scaling potentials being distributed throughout the entire formation.
The mechanical process has another limitation. The traditional method of using a “bucket” to treat pumpdown water tanks fails to adequately address the biological and scale loadings in that water. This manual treatment process is not easily verified and carried out in a “best guess” fashion between all stages.
Lastly, the current treatment method and mechanical process lacks a unit of measure to evaluate the performance of the treatment applied. In other words, the industry accepts that a static treatment rate at a set PPM is adequate for biocide and scale treatments for all water. The unit of measure is simply the amount of chemicals used not how well the chemical performed. These factors result in an ineffective biocide and scale inhibitor solution that contributes to limiting your well’s performance.
