NMR SEQUENTIAL FLUID CHARACTERIZATION

Abstract:

Methods and systems for determining location of hydrocarbon in unconventional plays are provided. The methods comprise at least two steps of measuring formation samples as received, as dried and/or as saturated using high resolution NMR, and subsequent processing of the NMR data to determine one of several formation properties or components where the formation property or the component can be used to locate an oil or gas reservoir, complete a well, and/or increase production efficiency. Also, the present methods provide a series of sequential and ordered combination of steps related to the financial evaluation of number of barrels of oil or cubic feet of gas which can be produced at a location.
