During the gas production testing of the Gasbuggy chimney, water-production rates increased from an initial 4 to 5 bbl per 10U6D standard cu ft of gas to 40 to 50 bbl per 10U6D standard cu ft of gas. This unexpected ocurrence hampered operations and increased waste disposal costs. A model is developed which calulates the amount of water produced from condensation of water vapor through the cooling and expansion of the gas in the production tubing. Results from this model are compared with the observed water production from Nov. 1968 through May 1969. This comparison shows that up to 7 times more water is being produced at high gas flow rate than can be explained by condensed vapor, indicating that water is being introduced into the production tubing in particular or liquid form. An examination of the radioactivity of the gas and water produced from GB-E indicates that the tritiated water vapor in the chimney and tubing has been diluted by extraneous water. It is concluded that a decrease in the bottom-hole pressure of GB-E results in Ojo Alamo water entering GB-E and either being produced or flowing down GB-E into the chimney.
