In our different studies for petroleum fluid analysis, we always assume that petroleum reservoirs are isothermal. Do you agree with this assumption? And if not, what is the impact of this assumption on the different calculations related to fluid analysis and consequently reserves calculations?
I think these papers could help you;

Reservoir temperature in accumulations depends on their occurrence depth and geothermal specifics of the giver Earth crust area. Observed temperatures vary from near 0°С in gas-hydrate accumulations to hundreds °С in deep-lying formations
reservoir is that portion of a trap that contains oil and/or gas as a single hydraulically connected system. And, many hydrocarbon reservoirs are hydraulically connected to various volumes of water-bearing rock, called aquifers
Temperature variations within a reservoir will depend on the heat transfer coefficients for the various geological strata and the heat flow, albeit these variations might be small they still exists. There is a vast literature particularly in the geothermal and volcanology areas that shows and illustrates these variations very well. I hope it helps
Petroleum reservoir could be considered isothermal for single layered depth. This assumption becomes invalid as the depth varies
Predominantly isothermal with localized variations due to cold water injection; EOR activities or interzone communications
