All,

Does anyone have experiece building pressure map / isobar map ? I want to ask some data and how to normalize the data.. such as

1. what kind of data we can use (MDT/RFT/DST/production) ?
2. as those data being taken with different years/data.. then how to normalize, one to each other area ?
3. normally is it better in psi points or PPG/SG points of data ?

thank you
