Biodegradable lubricating composition and use thereof in a drilling fluid, in particular for very deep reservoirs.

摘要

The present disclosure relates to a biodegradable lubricant composition, notably intended to be incorporated as an oil phase with high lubricating power in a drilling fluid or mud. This composition may be in a drilling fluid or as a fluid for fracture of underground formations. These muds or fluids contained in the composition of the present disclosure are particularly suitable for very deep drillings, offshore in deep water and/or sidetracked drillings or with a long shift.
