Chapter 5. Gas-Condensate Reservoirs

5.1 Introduction

Gas-condensate production may be thought of as intermediate between oil and gas. Oil reservoirs have a dissolved gas content in the range of zero (dead oil) to a few thousand cubic feet per barrel, whereas in gas reservoirs, 1 bbl of liquid (condensate) is vaporized in 100,000 SCF of gas or more, from which a small or negligible amount of hydrocarbon liquid is obtained in surface separators. Gas-condensate production is predominantly gas from which more or less liquid is condensed in the surface separators—hence the name gas condensate. The liquid is sometimes called by an older name, distillate, and also sometimes simply oil because it is an oil. Gas-condensate reservoirs may be approximately ...
