The aim of this study is to investigate effect of cement slurry consistency toward friction pressure
during oil/gas cementing operation. Completion of an oil/gas well has become more important because the
reserve has become harder to find. The oil/gas company cannot afford to lose million dollars they spent when
locating, drilling and recovering the oil from the Earth if they failed it. The safety, health and environment also
have become more important issue, because any completion problem can lead to prolong operation and creating
more hazard and risk. Cementing operation plays a very important role during completion because it creates
a secure conduit to bring the precious oil/gas to the surface and a place to install completion jewelry. During
cementing operation lost circulation can be one of the serious problems that arise. Circulation is said to be lost
when the cement slurry pumped flows into one or more geological formations instead of returning up casing
annulus. This is due to sum of hydrostatic pressure and friction pressure is exceeding fracture gradient. Method
that commonly used to calculate friction from American Petroleum Institute (API) assumed the cement slurry
will exhibit time independent nature. Cement slurry consistency was found to have significant effect to friction
pressure.
Key words: API , cementing, completion, friction pressure, lost circulation, thickening time, viscometer
