Storage and Disposal Wells

We provide a wide range of specialty well services to support hazardous and nonhazardous waste injection, storage, geothermal energy, and in-situ mining activities. Our professionals have the experience and expertise to meet the needs of industrial and commercial clients as well as the demands of state and federal regulatory agencies.

WSP is a leader in the design, drilling and maintenance of underground storage and disposal wells.

Comprehensive Technical Services

We have permitted, designed, installed, and repaired Class I (hazardous and nonhazardous) waste injection wells, Class II oilfield fluid wells and Class III solution mining wells throughout the U.S. and abroad. Our staff has developed proven project management procedures related to design, installation, workover, and repair projects, and are fully up to date with current technologies. Our designs include multiple downhole safety devices, the use of corrosion resistant alloy metallurgies, and other wellbore enhancements required by regulatory agencies for this type of application.

Routine inspection and maintenance of the wellhead and tubular components are needed to keep a well operating safely and efficiently. Typically, regulatory agencies will mandate mechanical integrity tests of an acid gas injection (AGI) well at two- to five-year intervals. We can coordinate the testing and submit the proper forms to the state, or respond to a well operation emergency when needed.

Our experience includes design and drilling management for saltwater disposal wells as well as AGI wells. Gas processing plants and refineries are turning to AGI wells as modern and efficient alternatives to outdated and expensive sulfur recovery units when removing H2S and SO2 from their products. In addition, large volumes of CO2 that would otherwise be vented to the atmosphere are also being injected downhole.

Overcoming Challenges

Our drilling engineers are experienced in drilling through difficult underground environments, including thick salt deposits, thick sections of “gumbo” shale, over-pressured zones, lost circulation zones, and underground disposal zones containing 100 percent waste. We have also permitted, designed, and installed numerous test wells to evaluate site-specific subsurface conditions and gather data to allow for appropriate project design and evaluation of project feasibility.

Our technical expertise and innovative approach help clients design, drill and maintain underground storage and disposal wells under various conditions safely and efficiently. Find out what we can do for you.
