Paper presented at the International Petroleum Technology Conference, March 23–April 1, 2021
Paper Number: IPTC-21412-MS
... Abstract In the greenfield development process, one of the key questions that needs to be answered is, "What is the range of EUR for a particular development concept and the associated completion method based on the existing range of subsurface uncertainties?" The key challenge then is how can...

Paper presented at the SPE Canada Unconventional Resources Conference, March 13–14, 2018
Paper Number: SPE-189802-MS
.... Of these methodologies, empirical methods, or DCA, are the most commonly used because of their simplicity. They basically rely on empirical curve fitting of historical production data to forecast future production and are more suitable for quickly estimating a well's EUR or a group of wells' EURs within a short period...
