Gregg Drilling’s Remediation Team utilizes their industry knowledge and experience to design and maintain a fleet of custom mobile injection systems. Combined with an array of pumping, tooling, and other design options, the team has the capability to accurately and cost effectively mix and inject in-situ remedial compounds and support various site remediation solutions.
High Performance Injection Rigs
Gregg’s mobile injection systems are fully self-contained and have integrated operator work stations, safety equipment, mixers, pumps, secondary containment, water storage, hydraulics, power, pressure regulators, and flow and pressure monitoring equipment. Gregg provides integrated mixing and pumping systems that can achieve injection rates between 0.1-100 GPM and can regulate injection pressure between 0-1500 PSI. With the use of Gregg’s multi-point manifolds, reagents can be delivered individually or simultaneously to up to 20 direct push points and/or injection wells.
- Enhanced Aerobic Biodegradation
- Enhanced Anaerobic Bioremediation
- Enhanced Reductive Dechlorination (ERD)
- In Situ Chemical Oxidation (ISCO)

- In Situ Sorption/Bioremediation
- Permeable Reactive Barrier
- Combined Remedies
- Groundwater Recirculation
With the use of our specially designed top-down, bottom-up, pressure-activated, or directional injection tools, we can improve vertical distribution and emplacement of remedial compounds. With the combination of our tooling and methodology, we are able to provide a cleaner and more precise injection process that allows us to place reagents within a wide range of lithologies.
