... balance time, to extract the constant pressure solution from variable pressure and production data. Then skin and wellbore storage effects are removed to show only the reservoir response. By accounting for pressure variation and removing skin and wellbore storage effects this method makes possible the use...

... and a possible loss of the well or the need to drill a sidetrack. Furthermore, this was also evidenced in the thin section, XRD, and XRF analyses showing mineralogical variations down to the inches scale, which is lower than the well-log resolution, making it challenging to identify. The overall composition...
