4.2 Answer the following questions 4.2.a For an undersaturated oil reservoir, assuming water and rock compressibilities are negligible compared to that of the liberated gas, the recovery factor is: B₁-Bri may be watten -Rsi)-Bg Conts 1 Conts 2+ Rp RE=P N This equation shows that to have high recovery factor we need to keep Rp as low as possible. Other than water injection: explain what can we do to keep Rp as low as possible. In your explanation answer what to do, where to operate and when to operate. You can use the following figure if you wish for you explanation. OWC production well sealing fault 4.2.b For a solution gas drive reservoir the performance criteria of daily producing gas oil ratio is expected to be as follows in the following figure below pressure decline 4.2.b.1 time R (producing GOR) 2 watercut (%) Bohematio of the production history of a solution gac drive reservoir Explain the reasons why do we have in the daily producing gas oil ratio curve the declining portions indicated by regions 1 and 2. 4.2.b.2 For an undersaturated reservoir is it possible to have an Rp vaule greater than Rsoi? Why? You may use the empty plot paper on the following page. Just change the axis numbers for each graph you make. 4.2 Answer the following questions 4.2.a For an undersaturated oil reservoir, assuming water and rock compressibilities are negligible compared to that of the liberated gas, the recovery factor is: B₁-Bri may be watten -Rsi)-Bg Conts 1 Conts 2+ Rp RE=P N This equation shows that to have high recovery factor we need to keep Rp as low as possible.
