Both invert and all-oil muds were used to drill the Jolliet project development wells. A comparison is presented which shows that all-oil muds performed better. The overall objective in designing the all-oil fluid was to provide the advantages of an invert-emulsion fluid while minimizing or eliminating the inherent shortcomings of the invert system. By removing the aqueous internal phase of the fluid, the emulsion's contribution to viscosifying the fluid and to filtration control is lost. More efficient viscosifiers and filtration-control additives, therefore, are required to compensate for these shortfalls. The fluid also has to accommodate, on a routine basis, small influxes of water. The system is described.
