The Issue: Bacteria in Oil and Gas Wells
The Solution: Treatment with Sabre's DiKlor® service, using chlorine dioxide (ClO2) stimulation process
Background
A Texas based oil and gas company operates a gas processing facility in Southeastern New Mexico. 700 barrels (bbls) of wastewater per day are produced at the facility and pumped to a disposal well in the San Andres formation.
The Issue: Iron Sulfide Plugging in Wellbore
The Solution: Treatment with Sabre's DiKlorSM service, using chlorine dioxide (ClO2) stimulation process
Background
A Texas-based oil company operates a producing field in west Texas. With a history of iron sulfide related problems, one of their wells experienced excessive workover costs and downtime.
The Issue: Hydraulic Fracturing (Frac) Water Reuse
The Solution: Treatment with ClO2
Background
A Rocky Mountain Oil producer was experiencing difficulty in reuse of fracturing fluids due to high contaminant and bacterial loading. Friction reduction and other fracturing chemical additive use rates were high or unfeasible because of the high contaminant levels. Disposal costs, fresh water costs, and water use concerns were severely impacting fracturing operations. High residual polymer levels and solids loading were contributing to high hydrogen sulfide production in the pits, causing safety and environmental concerns.
The Issue: Reducing Injection Pressure
The Solution: Treatment with Sabre's DiKlorSM service, using chlorine dioxide (ClO2) stimulation process
Background
Annual stimulation was performed on a west Texas well to reduce injection pressure.
The Issue: Frac Water Reuse
The Solution: Treatment with ClO2
Background
A Mid Continent Oil producer was experiencing disinfection and permitting difficulties using conventional Oilfield biocides. High bacterial loading and short contact times required the use of high dosages of conventional biocides that were both costly and of concern to the regulatory community.
The Issue: Restoration of Municipal Water Wells
The Solution: Treatment with ClO2
Background
A major Southern California municipality servicing a population of over 100,000 uses potable water source wells to supplement its surface water supply of drinking water. The wells began experiencing high bacteria levels, sulfur odors, and reduced production capacities. The primary problem identified was bacterial fouling and biomass accumulation in the wells. The municipality attempted remedial treatments with sodium hypochlorite and hydrogen peroxide. While initial flow-back results were promising, bacterial contamination levels equivalent to pre-treatment were observed within a few days. Additionally, no improvement was seen in the production capacity of the wells. Some of the wells had experienced up to a seventy percent decline in productivity while retaining the original rest water levels in the well, indicating severe fouling.
The Issue: Bacteria in Oil and Gas Wells
The Solution: Treatment with Sabre's DiKlor® service, using chlorine dioxide (ClO2) stimulation process
Background
A Texas-based oil and gas company operated nine producing and five saltwater disposal wells in eastern Utah. Over time, the field became progressively sour as a result of contaminated water used in completion and workover fluids.
