Using simple salt water, (NaCl or K2CO3), and electrolysis, produces a more cost effective, environmentally benign biocide, HOCl (hypochlorous acid), and/or an environmentally benign alkaline ( KOH) , production enhancing, super water wetting, well treatment solution. The production enhancement from using small 1000–3000-gallon alkaline (KOH) Catholyte treatments on two new wells in the S.E. Oklahoma, in the Oil Creek formation (19-degree API oil} resulted in 200- 600% increases in oil production, with little or no associated water production compared to high water production in 23 previous wells in the same field. Similar treatments near Holdenville, OK and in Shackleford, County, TX have shown similar trends with reduced water ratios alongside significant oil production increases in each treatment. Also, small annular treatments using HOCl anolyte for wellbore mitigation and control of APB and SRB bacteria causing rod failures are shown to mitigate H2S and subsequent rod failures due to bacterial corrosion. Results illustrate one year plus remediation results, supporting treatment designs, and cost effectiveness.
