Design and Evaluation of Tailored Chemical Injection Fluids for Enhanced Oil Recovery in Carbonate Reservoirs in The Rio Del Rey Basin

Abstract

This document presents a study on the interpretation of well log data from two wells, BVM1 and BVM2, in the Rio Del Rey ‎basin of Cameroon. The study focuses on analyzing gamma ray (GR), resistivity (RDEEP), density (RHOB), and neutron ‎‎(NDPHI) logs to identify potential sandstone reservoirs and characterize their properties.‎ ‎The document begins with an introduction to the Rio Del Rey basin, its geographical and geological settings, and the ‎importance of well logging in petroleum exploration. It then provides a detailed explanation of the various geophysical logs ‎used in the study, including gamma ray, resistivity, density, and neutron logs. Each log type is described in terms of its ‎measurement principle, interpretation, and significance in identifying lithology and fluid content.‎ The study employs a qualitative interpretation method, using the 'quick look' approach developed by Serra (1979) to analyze ‎log responses. The interpretation process involves combining GR, NPHI, RHOB, and RDEEP logs to highlight different ‎lithologies and identify potential reservoirs. The results show that two potential reservoirs were identified in the BVM1 well, ‎while one potential reservoir was found in the BVM2 well. The document concludes by emphasizing the essential role of well ‎logging in petroleum exploration and exploitation.‎ One interesting insight from this document is the use of Custom Markdown formatting to present scientific and ‎mathematical content, borrowing syntax from LaTeX. This approach enhances the readability and understanding of ‎complex technical information. Another unique aspect is the detailed explanation of the logging tools and their principles, ‎which provides valuable context for interpreting the well log data. The study also highlights the importance of combining ‎multiple log types to achieve a more accurate interpretation of subsurface formations and fluid content, demonstrating the ‎complexity and interdisciplinary nature of petroleum exploration‎.
