Scenario: You are an engineer working on a new oil well development project. Your team is analyzing the production data from an existing well in the same formation to predict the future performance of the new well. The existing well has been producing for 5 years with an average daily production rate of 100 barrels of oil. You need to determine the expected production duration of the new well, assuming a similar decline rate.
Task: Using the information provided, estimate the expected production duration of the new well, assuming a similar decline rate as the existing well. Provide your calculations and explain your reasoning.
This exercise requires more information to provide a precise answer. You need to know the decline rate of the existing well to make an accurate prediction. Here's how to approach the problem with more information: 1. **Determine the decline rate:** Calculate the annual production decline rate of the existing well. This could be a percentage decrease in production per year. 2. **Apply the decline rate to the new well:** Assuming a similar decline rate, apply that rate to the new well's production. 3. **Calculate the estimated production duration:** Based on the decline rate and expected production decrease, you can estimate how long the new well will continue to produce economically viable amounts of oil. **Example:** If the existing well has an annual decline rate of 5%, then the new well is expected to have a similar decline rate. You can then estimate the production duration by calculating how many years it will take for the production rate to fall below an economically viable threshold (e.g., 50 barrels per day). **Without the decline rate, you can only make a general estimate. For instance, if the new well is expected to have a similar production profile, it may also produce for 5 years. However, this is a rough approximation and not a precise prediction.**
