Historical records on oil, gas, water flowrates, results of formation pressure surveys and flowing pressure (THP or BHP).
The flowrate data is normally available as daily or monthly records of surface flowrates \{ q_W, \, q_O, \, q_G, \, q_{WI}, q_{GI} \}:
q_O(t) | q_G(t) | q_W(t) | q_{WI}(t) | q_{GI}(t) |
---|---|---|---|---|
oil production | gas production | water production | water injection | gas injection |
