History of BOP Fluids First BOP fluids were normal Hydraulic Oils High Viscosity No Seawater Tolerance Flammable Compressible Lighter Than Seawater

History of BOP Fluids Soluble Oils More Environmentally Acceptable Closer SG to Seawater Less Flammable Easier to Store Low Viscosity Susceptible to Instability Too Biodegradable

History of BOP Fluids Polymer Solutions Much More Environmentally Acceptable Easier to Store Non Flammable Stable Micro-organism Resistant Low Viscosity

Modern BOP Fluids 100-50:1 Dilution Low Toxicity High Biodegradability Low Viscosity Extremely Stable (even with seawater) Good Lubrication Corrosion Resistance Microbiological Resistant

Components in Modern BOP fluids Corrosion Inhibitors, Normally Amine Based Lubricants, Many Types Used Biocides Surfactants, Soaps or Solvents.

Main BOP Fluids on The Market Stackmagic 200 Stackmagic 200N UK 50 Erifon HD856 Erifon HD2000 Erifon HD603 Erifon Pilot Line Fluid

Stack Magic Manufactured by Houghton Vaughn 100:1 mix, Good all round fluid High resistance to micro-organisms Poor toxicity figures Stackmagic 200N appears to have some biocide removed. Still does not have very good toxicity figures but is acceptable to SFT and DTI.

UK 50 Manufactured by Blacksmiths 50:1 mix ratio or premixed Green in colour

Erifon HD 856 Approved by all equipment manufacturers. Diluted 100:1 For general use Relies on Molybdenum for lubrication No up to date HOCNF Being phased out

Erifon HD 2000 100:1 Dilution. Developed primarily for use in South East Asia. Extremely resistant to microbiological attack. Because of high temperatures and poor water supply.

Erifon HD 603 100:1 to 50:1 mix Newest fluid on the market Incorporates advantages of HD856 and HD2000. Most environmentally acceptable fluid on the market. Recommended by all BOP equipment manufacturers.

Physical Properties of Erifon HD603

Important Physical Properties The most important indicator of problems and property to maintain is the pH. This maintains bacterial resistance. Low pH indicates presence of micro-organisms. And corrosion inhibition. Low pH will cause corrosion.
