PGE 362 Homework 4 Due at the start of lecture on March 2. (1) Using the Hagedorn and Brown correlation of section 7-4.3 in the text please predict the average fluid density for the following conditions. Using Figure 7-9, what is the flow regime? l g 2.441" 100 STB/Day 10,000 MScf/Day 0.78 0.65 =74 dynes/cm 2000 psi 150 deg F l g D q q p T γ σ = = = = = = = Hint: This is not bubble flow. The velocities must be in situ velocities, not at standard conditions. Use the PPS software to predict fluid properties. (2) A chip of scale has been recovered from a rod pump in a West Texas oil well. The scale chip effervesces violently and dissolves in 15% hydrochloric acid. A produced water analysis shows a positive scale index (SI) for calcium carbonate, which means scaling is likely.
