Exercise: Observing Well Performance
Scenario: You are a production engineer monitoring the performance of a well. The following data has been collected over the past week:
| Day | Oil Production (bbl/day) | Gas Production (Mcf/day) | Water Production (bbl/day) | Pressure (psi) | |---|---|---|---|---| | Monday | 500 | 1000 | 50 | 2000 | | Tuesday | 480 | 980 | 60 | 1980 | | Wednesday | 460 | 960 | 70 | 1960 | | Thursday | 440 | 940 | 80 | 1940 | | Friday | 420 | 920 | 90 | 1920 | | Saturday | 400 | 900 | 100 | 1900 | | Sunday | 380 | 880 | 110 | 1880 |
Task:
- Analyze the data: Observe the trends in oil, gas, water production, and pressure over the week.
- Identify potential issues: Based on your observations, identify any potential problems or concerns with the well's performance.
- Propose solutions: Suggest possible solutions to address the identified issues.
Exercise Correction
**Analysis:** * **Oil Production:** The well's oil production has been steadily decreasing over the week. * **Gas Production:** Gas production also shows a consistent decline, similar to oil production. * **Water Production:** Water production has been increasing steadily over the week. * **Pressure:** The well's pressure is dropping gradually over the week. **Potential Issues:** * **Well decline:** The decreasing oil and gas production, coupled with increasing water production and falling pressure, suggests a potential well decline. This could be due to factors like reservoir depletion, formation damage, or water coning. * **Water coning:** The rising water production indicates that water may be encroaching into the oil-producing zone, reducing oil recovery. **Proposed Solutions:** * **Production optimization:** Analyze production data and adjust wellhead pressure to maximize oil production and minimize water production. * **Stimulation:** Consider well stimulation techniques (e.g., acidizing, fracturing) to enhance reservoir productivity and counteract well decline. * **Water management:** Implement strategies to manage and dispose of produced water effectively. * **Monitoring and surveillance:** Continue to monitor well performance closely and adjust production strategies as needed.
