Saltwater Disposal Case Study
A salt water disposal system located in East Texas, injecting 500 BWPD of produced water from the Paluxy, Glenrose, Eagleford and Sub Clarksville formations, had a history of calcium carbonate scale deposition, Co2 corrosion and oil carryover.
In addition to the five chemicals used to try and control these problems, the system had to be acidized monthly to maintain injection pressure below 1200 psi.
The following table details the conventional treatment program:
Bio Tech designed and implemented a microbial treatment program at the SWD. The goals of this treatment were to:
1.) Control iron sulfide and calcium carbonate deposition in the
injection system.
2.) Reduce or eliminate chemical and acid treatments.
Bio Tech Product/Treatment Details
This treatment program proved very successful. The injection rates and pressures have remained constant. All chemical and acid treatments have been terminated. Water quality has been improved (See Water Quality Graph).
The operator has saved $1,350 per month in treating costs while eliminating their environmental exposure. After the initial results,
the program was expanded field wide.
