|Inventors:||MICHAEL, Gerald E.
SUMMERFIELD, Aaron K.
|Title:||TIME-SERIES GEOCHEMISTRY IN UNCONVENTIONAL PLAYS|
Method of optimizing well placement in an unconventional reservoir, by obtaining a plurality of produced oil, produced water and produced gas samples from an unconventional reservoir over a period of time, and obtaining a plurality of rock samples from the reservoir. Each of those plurality of samples is chemically fingerprinted, as well as assigned time and location identifiers. This data is then used to generate a plurality of reservoir maps over time and those maps then used to optimizing well placement in the reservoir.
