Prediction of Liquid Holdup in Large Diameter Tubing

The goal
and achievement of this thesis is the measurement of downhole liquid
holdup. An instrument was designed, constructed, and field tested using
gamma densitometry to monitor holdup. To the author's knowledge, this is
the first time holdup has been measured at depth in a well. This thesis
describes the construction and operation of this device in detail, and
presents a limited amount of data correlating holdups measured by it
with those predicted by various standard liquid holdup prediction
methods. Computer programs were developed for this comparison as well as
for stability analysis of the experimental system and source code
listings are located in the appendix.
