... inhibitive than other water-based drilling fluids used in the area. The tests prove that CBF, while not as inhibitive as oil-based mud (OBM), is sufficiently inhibitive to be used as an alternative to OBM in many areas where OBM has previously been thought necessary. Advantages of CBF over conventional...

... for oil-based muds in many situations, and preliminary field results are encouraging. The trend to polymer muds, in general, has reduced consumption of traditional lignosulfonate additives and other organo-metallic complexes. Weighting agents also have been affected. Barite ore sources are scrutinized...

..., formations are frequently encountered which lose physical integrity when exposed to aqueous drilling fluids. In almost all cases these are uncemented or young shales. Prior to the introduction of oil-based muds, great difficulty was encountered in drilling through these types of shales. The first use of oil...
