M&D Industries are a widely recognised and respected provider of oil and gas production chemicals, based in the USA. Their portfolio of well-known products include names such as Ultra Seal, Poly Plug, Liquid Bridge Plug, Pro Blend, and Ultra Spacer. M&D products are manufactured at a secure 100,000 square feet warehouse and manufacturing facility. All products are lab tested following a strict QA/QC protocol, with each bag, pail or tote stamped with a QA/QC number. Samples of each batch are then retained for two years.


Rexos produces the unique orange-based wax and asphaltenes dissolver, OrangeWorks, which also doubles as an effective cleaner for sludge tanks while promoting oil and water separation. It is also used as a general maintenance degreaser, replacing suspected carcinogenic products such as toluene and xylene.


Brenitech is an innovative chemical developer responsible for the highly-effective wax and corrosion inhibitor PSI. This superior product was developed in the demanding environment of the Canadian tar sands. PSI further helps promote the rapid separation of the oil and water phases.


Alongside the innovative chemical solutions provided by our Principals, WellTech develop and distribute our own propriety oil and gas solutions, including PowerPickle and PowerSurf, both used in casing cleanup operations. We also produce mercury decontamination chemical EnviroMerc, and preflush stimulation and descaler Pentaflow, all rigorously tested at our WellTech Engineering laboratory.
