Gas Injection
The temperature profiles for a gas-injection well (Fig. 8.10 ) are entirely similar to
those of a water-injection well, and the same observations apply.
Further examples of liquid and gas production and injection profiles—together
with the effects of casing leaks, casing-formation annulus flow, etc. are given in a
paper entitled “Temperature Logs in Production and Injection Wells,” by A. Poupon
and J. Loeb. The reader is encouraged to read this paper in its entirety.
