Our orders are delivered strictly on time without delay 
1. You have been asked to look at a grouping of wells, a ten total well package, and you have been asked to develop type curves for each of the ten wells from information that you received from Drilling Info. You are only interested in the gas production and will ignore both crude and water for this exercise.
a. Develop ten type curves using the Arps’ Model?
b. Develop ten type curves using the Duong Model?
c. Describe the differences between the models?
d. What is the error difference between the models?
e. From your results, what can you ascertain about the wells (i.e. are the wells conventional or unconventional)?
f. Which empirical model would you use to represent the wells that you plan to design a gas gathering system around?
g. Choose the best Arps’ Model and Duong Model and post the graphical results below.
2. Develop two probabilistic type curves using the results from the Arps’ and Duong Models.
a. Use the procedure laid out in the lecture slides and attach your results to this document.
b. Develop a production forecast model using the best type curve from exercise one for both Arps’ and Duong Models.
c. Develop a production forecast model using the probabilistic type curves that you have found.
d. What observations can you make from both methods?
