The Role of Acid in Hydraulic Fracturing
Oil and gas operators have used acidizing to stimulate and maximize well productivity for more than 100 years. Hydrochloric acid (HCl) acidizing dissolves materials blocking or restricting the flow of oil and gas (carbonate-based materials in carbonate formations and sand, feldspar, and clay particles in sandstone formations) to create new pathways or clean existing channels.
Treating pathways with custom HCl acid blends allows formation fluids to flow freely through pore spaces into the well.
More. Energy. Faster.
Maximum Efficiency at Every Stage
Acid treatment plays a critical role in stimulating initial productivity in new wells and maximizing recovery and restoring productivity of aging wells in decline. OneCor brings decades of experience to help operators select and design effective acid treatment processes for complex jobs involving heterogeneous geologic formations.
We blend, pump, and manage logistics for acid treatments ideally suited to the composition, permeability, and logistical challenges of each formation.
OneCor solutions enable acid washing to clean out scale and other debris that restricts tubular flow as well as matrix acidizing to dissolve material restricting flow in a productive formation.
Pumping acid into a wellbore or geologic formation improves injectivity
In the recent shale boom regions, acid plays a crucial role as a preliminary step in the hydraulic fracturing process to provide the cleanest possible formation face, enable easier fracture creation, and maximize the performance of proppants for enhanced well productivity. Similarly, in carbonate formations, acid fracturing serves to both create new fractures and dissolve acid-soluble material, clearing more efficient flow pathways to the wellbore and improving long-term production potential and cost.
Hydrochloric Acid Blending: Key to Well Stimulation
One of the most critical services we offer is hydrochloric acid blending, which is essential for well stimulation and acidizing in oilfield operations. Hydrochloric acid plays a crucial role in enhancing well productivity by dissolving blockages, improving flow rates, and preparing formations for further extraction. Our custom hydrochloric acid blends are designed to meet the specific needs of your well, ensuring efficiency, safety, and superior results.

End-to-End Solutions for Completion, Production and Recovery
An important preliminary step in hydraulic fracturing, matrix acidizing involves pumping HCl ahead of the fluid carrying the proppant to provide the cleanest possible formation face and easier fracture creation. Once the acid has been pumped and directed to optimize permeability, the well gets brought on production.
As materials restricting the flow of fluids dissolve, the acids used in fracturing get partially consumed and neutralized but require specialized handling to recover and remove. OneCor can assist at this stage with H2S scavenger solutions and the safe removal of spent acid, oil, gas, and water recovered from the formation.
