PETR 317 MIDTERM EXAM 2 WITH COMPLETE SOLUTIONS 100% VERIFIED LATEST
UPDATE!!
Bo - (ANSWER)Oil Formation Volume Factor- volume of dissolved gas and oil at reservoir
conditions/volume of oil entering the stock tank at standard conditions.
Specific Gravity of oil- Gamma o - (ANSWER)= denisty of oil/ density of water, both at same temperature
and pressure
API gravity - (ANSWER)= (141.5/ gamma o)- 131.5
Rs - (ANSWER)Solution gas oil ratio= volume of dissolved gas produced at surface at standard
conditions/ volume of oil entering the stock tank
Rs max is also - (ANSWER)Rsb, solution gas oil ratio
Bt - (ANSWER)total formation volume factor
= gas released + volm of oil at a given temp/ total oil
Gamma O - (ANSWER)Ma/29
Ppr - (ANSWER)Pseudoreduced pressure, P/Ppc
Tpr - (ANSWER)Pseudoreduced, T/Tpc
Bg= - (ANSWER).00502*Z*T/ P
Case 1 - (ANSWER)1.Find total mass and total volume of c3+ ( add h2s to c3)
2.Find W1 and W2 and then calculate use the chart to find ppo/pc3+
3.find Ppo and then adjust for pressure, temperature and h2s if needed
