Descriptiontext

Petrotek Corporation is a privately held engineering consulting firm headquartered in Littleton, Colorado, founded in 1993 to provide cost-effective contract services for subsurface fluid flow and injection well projects. The company delivers technical engineering evaluation, regulatory permitting, reservoir characterization, and field operations services to industrial operators, governmental agencies, and mining companies across the United States, with active international reach into Australia, Canada, Kazakhstan, Paraguay, South Africa, and Turkey. Its customer base spans oil and gas majors, smaller independent operators, hard-rock mining companies, ethanol and chemical plants, refineries, gas storage operators, food production, pharmaceuticals, and municipal water suppliers, with explicit emphasis on regulatory-compliant wastewater management that protects drinking water sources.

The firm's core technology is deep expertise in injection well engineering and subsurface fluid flow, organized across six service lines: Injection Well Services (Classes I, II, III, V, and VI), Carbon Dioxide Capture and Storage (CO2 CCS) including Class VI UIC permitting and 45Q qualification, Oil and Gas E&P technical services, In-Situ Recovery (ISR) Uranium and Copper consulting, Mining hydrogeology, and Safety/regulatory compliance. Underlying technical capabilities include feasibility studies, permit preparation, reservoir simulation, mechanical integrity testing, well design and drilling supervision, hydrogeological characterization, fate-and-transport modeling, and reserves/economic analysis. The team combines credentials from major operators (Halliburton, Burlington Resources, Ultra Petroleum, Western Company of North America) and the US EPA, with the three managing principals (Wes Janes, Hal Demuth, Ken Cooper) collectively bringing more than 90 years of industry experience.

Petrotek operates a professional-services business model, generating revenue through custom, quote-based consulting engagements typically structured as multi-year contracts. Pricing is not publicly disclosed and varies with project scope, regulatory complexity, and field operations intensity. Go-to-market is sales-led and relies on a professional website, conference presence (GWPC, NGWA, uranium symposiums), publication-driven thought leadership, and direct enterprise engagement with industrial and governmental clients. There are no disclosed external investors, M&A activity, or institutional backing; ownership remains with the managing principals.

EIN PresswireAmerican Uranium Welcomes U.S. Geological Survey’s Restoration of Uranium to their Critical MineralsThe U.S. Geological Survey restored uranium to its 2025 Critical Minerals List, a designation American Uranium Limited welcomed as a pivotal development for the company and the U.S. nuclear sector. American Uranium is advancing its Lo Herma ISR uranium project in Wyoming's Powder River Basin, which hosts an 8.57 Mlb U₃O₈ resource and is one of the few near-term, low-cost ISR uranium development opportunities in the United States. The company has commenced Phase 1 of a two-phase resource development drilling program and appointed Petrotek Corporation to conduct hydrogeological testing ahead of Scoping Study updates in 2026.PR NewswireDenison Announces Independent "Proof of Concept" Achieved for Application of ISR Mining Method at Phoenix and Details of 2020 ISR Field ProgramDenison Mines Corp. announced that Petrotek Corporation's hydrogeologic model for the Phoenix uranium deposit demonstrated "proof of concept" for the application of In-Situ Recovery (ISR) mining method, based on data from the 2019 field test at the Wheeler River project in northern Saskatchewan. The simulation using 18 extraction wells and 33 injection wells showed balanced operational flow of 105.5 GPM extraction and 105.4 GPM injection, with approximately 80% of injected fluids captured over a 180-day simulation period. The company also outlined its 2020 ISR field test program designed to further validate the hydrogeological model and prepare for future feasibility studies, including a potential in-ground lixiviant test or ISR demonstration.PR NewswireDenison Announces Positive Initial Results from ISR Field Test Program at Phoenix Test Area 1Denison Mines Corp. announced positive initial results from its ISR field test program at Test Area 1 of the Phoenix deposit within the Wheeler River Uranium Project in northern Saskatchewan, Canada. The pump and injection tests confirmed hydraulic connectivity between all test wells across the 34-metre strike length of the ore zone, providing significant preliminary indications of the suitability of ISR mining at this location. The company engaged Petrotek Corporation to conduct the testing, and the results will inform the location of large-diameter commercial-scale wells and contribute to a hydrogeological model for the upcoming Feasibility Study.PR NewswireDenison Announces Initiation of ISR Field Testing as the Summer Field Program Commences at Wheeler RiverDenison Mines Corp. has initiated in-situ recovery (ISR) field testing at its Phoenix deposit within the Wheeler River Uranium Project in northern Saskatchewan, Canada, as part of its summer 2019 exploration program. The company engaged Petrotek Corporation to design and implement this testing, which aims to collect hydrogeological data to de-risk the project and support a detailed feasibility study. Additionally, Denison is expanding environmental baseline data collection and conducting approximately 5,000 metres of diamond drilling to follow up on uranium mineralization along the K-West trend.
