Log Permeability And Injection Log Tool Comparison, Upper Shale Member Of Zubair Formation In X-Field As Case Study

Abstract

This study compares permeability enhancement and water injection, two crucial techniques in optimizing hydrocarbon recovery.  Both methods aim to maximize production rates and ultimate recovery from oil and gas reservoirs.  The essay analyzes the principles, applications, advantages, and limitations of each technique.  Water injection, a common secondary recovery method, involves injecting water into the reservoir to mobilize hydrocarbons towards production wells.  A comparative analysis will be presented to evaluate the effectiveness and suitability of each approach in different reservoir conditions. This study assesses the effectiveness of reservoir stimulation treatments, such as hydraulic fracturing and acidizing, by analyzing changes in injection performance. An increase in injection rates post-treatment indicates improved permeability and reservoir connectivity, facilitating fluid flow. Additionally, a decline in wellhead and borehole pressures further confirms successful stimulation. Comparative analysis of injection volumes before (2016) and after (2017) treatment reveals a substantial rise from limited volumes (~200 barrels) to over 2000 barrels in targeted reservoir zones, demonstrating the positive impact of stimulation methods on reservoir injectivity and flow characteristics.
