Abstract: Solid, waxy 1-olefins may be converted to low viscosity liquid products by carrying out a double bond isomerization in the presence of a solid acidic catalyst such as an acidic clay or a zeolite under mild conditions. The olefin isomer products are useful in the formulation of well fluids such as drilling muds, especially useful in offshore drilling. The preferred oils for making up the well fluids are formulated with a hydrocarbon oil blend of the low viscosity olefin isomer together with a C.sub.12 to C.sub.18 paraffinic hydrocarbon of petroleum origin and a C.sub.10 to C.sub.32 olefin such as tetradecene-1. The fluids exhibit good biodegradability and are non-toxic to marine organisms; they also meet viscosity and pour points specifications for formulation into oil based muds.
