Problem Set

  1. You are given two different phase envelopes (VLE region) that represent two different gas reservoir fluids. The first of them has a larger PT envelope covering larger P,T ranges. The other covers a fairly narrow P,T range. What do you conclude? Speculate on the type of gas reservoir for each case. Justify your answer.

  2. In order to design the appropriate production scheme for a gas reservoir recently discovered, what type of VLE calculation do you think is more valuable? Explain in detail.
