Abstract

Stringent environmental regulations and technical requirements of difficult formations such as shale demand the use of functional mud system to complete a well safely and economically.
The economic viability of 50/50 oil-water ratio invert emulsion which uses vegetable oil and egg yolk as a non-toxic emulsifier was evaluated.
The evaluation showed less cost of mud formulation by 67% and disposal by 47.5%. This equate to saving of $55.82 per barrel of invert emulsion formulated and $28.50 per barrel disposed.
The low oil-water ratio mud is viable for low fluid loss for enhanced wellbore stability and less oil retained on drilled cuttings
