When we talk about the applied fundamental theory for the deep well testing research, the mechanical analysis of the tubular string is normally a very complex task, taking into account that the tubing pressure and fluid temperature have a large effect on the tubular string force.
During the well testing, the methods that are commonly utilized to determine the pressure/temperature of the string would include measurements from thermometers and pressure gauges that are located in the tubing, pressure/temperature measurements at only the well bottom and well head. With these measurements, personnel will be enabled to duly predict the complete distribution using theory analysis technology. Predicting accurate temperature and pressure profiles in flowing wells can greatly enhance hydrocarbon production.
However, for gas wells with HTHP, standing for the "High Temperature High Pressure" is in most cases difficult to operate thermometers and pressure gauges within the tubing itself, thus theory analysis shall be used serving as a feasible and effective method. An excellent volume to be appreciated by all people engaged in oil exploration/production, including those working offshore.
