ESTIMATIONS OF RESERVOIR PARAMETERS WITH A MULTIPLE-STORAGE PHENOMENON IN DRILL STEM TESTS FOR NO PRODUCTION AT SURFACE

A method of estimating reservoir properties is disclosed. The method includes obtaining downhole pressure data during a drill stem test in a wellbore penetrating a reservoir, computing a first linearity measure of a first diagnostic plot, wherein the first diagnostic plot represents a first dependen...

Zusammenfassung:A method of estimating reservoir properties is disclosed. The method includes obtaining downhole pressure data during a drill stem test in a wellbore penetrating a reservoir, computing a first linearity measure of a first diagnostic plot, wherein the first diagnostic plot represents a first dependency of the downhole pressure data on a linear-scale with respect to inverse time on a linear-scale, determining, based at least on the first linearity measure, data sufficiency of the drill stem test, and generating, from the downhole pressure data and based at least on the data sufficiency, an estimation of the reservoir properties.
