Production data has been fit to a Fetkovich type curve. Given the following information, answer the questions:
Date of first production plotted for the Fetkovich type curve match is 1/1/95.
Value for Di from Fetkovich type curve match is 0.35 per year.
Value for Qi from Fetkovich type curve match is 1,500 BOPD.
Effective date of reserve report is 1/1/2002.
Cumulative production through 12/2001 is 250,000 BO.
Estimated value of "b" is 0.30 from the Fetkovich type curve.
1. Illustrate what are the values for Qi and Di on the effective date of the study?
2. If the economic limit is 20 BOPD, estimate the ERR.
3. When will the economic limit be reached (years from the 1/1/2002 effective date)?
4. What is the EUR for this well?
