The DCA of an individual well is founded on the same basis as the fluid-flow principles that are used for pressure-transient analysis of a single well in a reservoir domain and therefore can provide scientifically reasonable and accurate results. However, when used for a group of wells, a lease, or a reservoir, the DCA becomes more of an empirical method. Plots from the DCA reflect the reservoir response to the oil withdrawal (or production) under the prevailing operating and reservoir conditions, and they continue to be good tools for estimating recoverable hydrocarbon volumes and future production rates. For predicting the total recov\u00aderable hydrocarbon volume, the DCA results can help the analyst to evaluate the reservoir performance under any of the three phases of reservoir productive life\u2014primary, secondary (waterflood), or tertiary (enhanced oil recovery) phases\u2014so long as the historical production data are sufficient to establish decline trends at the end of the three phases.", "description": "iv, 20 p.", "publisher": {"@type": "Organization", "name": "U.S. Geological Survey"}, "author": [{"@type": "Person", "name": "Jahediesfanjani, Hossein hjahediesfanjani@usgs.gov", "givenName": "Hossein", "familyName": "Jahediesfanjani", "email": "hjahediesfanjani@usgs.gov", "identifier": {"@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0001-6281-5166", "url": "https://orcid.org/0000-0001-6281-5166"}, "affiliation": [{"@type": "Organization", "name": "Eastern Energy Resources Science Center"}]}], "funder": [{"@type": "Organization", "name": "Eastern Energy Resources Science Center", "url": "https://www.usgs.gov/centers/geology-energy-and-minerals-science-center"}]}
