between horizontal permeability of 400 and 800md but when horizontal permeability reduces from
400md to 100md, both gas and oil recoveries decreases (figure 10). In addition to that in figure 10,
is observed that, for each reservoir horizontal permeability, the gas recoveries are practically
independent of gas production rate, while the oil recoveries slightly decrease with increasing gas
rate. They also found that, for the same gas rate, as the reservoir horizontal permeability decreases
from 800 to 100md, the total water production increases, water breakthrough occur earlier and
field production life becomes longer (figure 11 & figure 12).

Permeability Anisotropy

CONCLUSION

This paper presented a review of the effects reservoir and production factors on the ultimate recovery and production behaviors of gas condensate reservoirs. Recovery and production behaviors of oil reservoirs have also been highlighted. From this study, it has been concluded that, for optimizing the gas production and development of gas condensate reservoirs, the following
points should be adhered;
Low gas production rate is more preferred in order to prolong field production life,
minimize water production and water breakthrough time in gas reservoirs. However, the
influence of gas production rate on gas recovery is almost negligible.
