.... Viscosity of micellar dispersions plays an important role in treatment results. In those cases where treatment results were not as good as the average, it was felt that viscosity was too high for the formation being treated. New dispersions with adjustable viscosities should solve this problem. REFERENCES 3...

.... Production of 19° API oil, ranging in viscosity from 1000 to 3000 cp. is from the shallow Carrizo formation (500 to 600 feet). The oil accumulation is anticlinal, bound~d on the north by a fault and elsewhere by the oil-water contact. (See Figure 1.) Although the sand is generally very clean, and has...

... as well as those of high permeability. The viscosity of the gelling chemical is quite @w, ranging from 1.0 to 1.5 centipoises at 75 F. At bottom hole temperature, the gelling chemical viscosity is a fraction of the 75°F viscosity, Handling and disposing of the unwanted water from such reservoirs has long...
