Memory Production Logging Tool (MPLT) in a Cross Flow

Abstract

The objective of this study is to investigate the cross-flow phenomenon in three wells in the Rhourd-Nouss field. The interpretation of the Multi-Phase Logging Tool (MPLT) data was performed using the Emeraude software. The interpretation of the MPLT conducted on September 31, 2023, for well RN-111 revealed cross-flow between reservoir A2 and TAGI. Additionally, the interpretation of the MPLT conducted on October 9, 2023, for well RNA-8 indicated no water production and a discrepancy between the surface flow rate measured by MPLT and that measured by the well test. The interpretation of the MPLT conducted between June and October 2023 on well RNSE-68 showed no change in total well test flow rate and no water production. This study successfully differentiated between waters and their impacts, collected various data and information about the reservoir, and demonstrated the significance of MPLT in cross-flow detection
