| 7.3.4 Reservoir and Well A Design Safety Case is only required as a precursor to a Production Safety Case. As such well and reservoir characteristics need only be described here a well that is intended for production purposes whether that be hydrocarbon production, water injection, or otherwise. An exploration well would not need a Design Safety Case. 52 7.3.4.1 Reservoir The following information should be provided for the reservoir or reservoirs that the wells) is located in Seismic anomalies related to shallow gas Formation geological details Basic reservoir data, including o Pressure o Temperature and o Depth to reservoir tops and reservoir thickness. Reservoir fluid composition and A specific note should be made of the presence of HS and CO 2 7.3.4.2 Well The following should be described for each well, with suitable diagrams where appropriate Well identification and top hole location (either specific point or defined area Purpose of well (production, injection, etc Depth references List of offset wells that are relevant for this particular well Well operating parameters o Maximum expected operating pressure and o Maximum and minimum expected operating temperature Overburden geological data o Geological setting Well construction data o Preliminary well trajectory and o Barrier policy.
