... Abstract The Seria field was discovered in 1929 and the present development concentrates on in fill drainage present development concentrates on in fill drainage and secondary recovery. The field consists of a number of faulted blocks and stacked reservoirs. At the end of 1984, 196 wells out...

... ta the slurry resulted in an increase in surfoce mixing viscosities. Ta offset this effect, the mix water concentration was increased which required that the hematite content be increased to 34% to achieve the desired 17.2 ppg slurry density. A higher concentration of dispersant was used to lawer...
