Evaluation of water production from the Gasbuggy reentry well

Technical Report ·
OSTI ID:5372660
;
During the gas production testing of the Gasbuggy chimney, water production rates increased from an initial 4 to 5 bbl per 10/sup 6/ standard cu ft of as to 40 to 50 bbl per 10/sup 6/ standard cu ft of gas. This unexpected occurrence hampered operations and increased waste disposal costs. A model is developed which calculates 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 rates than can be explained by condensed vapor, indicating that water is being introduced into the tubing in particulate or liquid form. A correlation of excess water with the pressure, temperature and gas-flow velocity parameters was performed to determine the relationship between this excess water and these parameters. It was found that the excess produced water varied linearly with downhole pressure when a threshold gas flow velocity was exceeded.
