5-10. You are analyzing an oil well where the rate is 141 bopd at the beginning of the year and 91 bopd at the end of the year. The economic limit is 3 bopd.

510.You are analyzing an oil well where the rate is 141 bopd at the beginning of the year and 91 bopd at the end of the year. The economic limit is 3 bopd. a) What is the effective decline rate (1/year) if the production declines exponentially? b) What is the nominal decline rate (1/year) if the production declines exponentially? c) What is the EUR for this well (initial rate is 141 bopd), assuming the smooth curve fits the data perfectly? d) If you had incorrectly used the effective decline rate instead of the nominal decline rate in Equation ( 0.j) , what value would you have calculated for EUR for part c of this
