Study of condensate removal from wells

Abstract

A pressure profile of well No. 218 in the Karadag condensate field showed that pressure did not vary linearly with depth. Calculations indicated that at depths of 3,000-3,640 m, produced fluid had a density of 0.29g/ cmU3D, whereas pure condensate gas should have a density of 0.11g/cmU3D. Apparently liquid was accumulating in the well. Other data showed that gas velocity in the well at various depths varied from 6 to 11 m/sec. It was also found that this same range of gas velocities was sufficient to prevent liquid accumulation in other wells. In an effort to solve this problem, the upward flow of gas-water and of gas-condensate mixtures in tubes was studied. Each had a different flow regime. Gas-condsensate formed foam, whereas the gas-water mixture did not. This resolved the problem, since foam is known to aid the removal of liquid by gas. Additional research showed that water was present in, and promoted accumulation of, liquid in well No. 218.
