4 Linear Interpolations... I think.

Here are 4 tables of iterated values for bottom hole pressures in CO2 injection wells. I’d like to be able to input a Surface Pressure (Psurf), TD (total depth), average fluid temperature Tavg, and CO2% and have excel go find the best approximation of the bottom hole pressure from the tables. Basically it needs to do 4 interpolations. I am totally stumped. Any help at all would be much appreciated.

Thanks

John
