End of Well Report Exercise
Scenario: You are a geologist working for an oil and gas company. You are tasked with reviewing an End of Well Report for a recently abandoned well. The report indicates that the well encountered a major geological fault during drilling. However, the well was still completed and produced for several years.
Task: Based on this information, what key questions would you want to investigate further in the End of Well Report? How might these questions help you understand the well's performance and potential future development opportunities?
Exercice Correction
Here are some key questions to investigate:
- **Nature of the Fault:** What type of fault was encountered (normal, reverse, strike-slip)? How did the fault impact the wellbore trajectory and drilling operations?
- **Reservoir Impact:** Did the fault compartmentalize the reservoir? How did the presence of the fault affect reservoir properties (porosity, permeability) and production? Were there any pressure differences across the fault?
- **Production Data:** Did the well's production rates decline significantly after encountering the fault? Was there any indication of water influx or other fluid movement related to the fault?
- **Seismic Data:** Was there any evidence of the fault in the seismic data available for the area? Did this data match the observations in the End of Well Report?
- **Future Development:** Based on the understanding of the fault's impact on the reservoir, could this fault have implications for potential future development in the area? Are there any opportunities for re-entry or infill drilling to access other compartments or fault blocks?
By investigating these questions, you can gain a more comprehensive understanding of the well's performance in relation to the geological fault. This knowledge can be valuable for planning future development activities and mitigating risks associated with similar geological features in the area.
