Abstract
Formation evaluation challenges in mature oilfields of South Iraq are aplenty. From arresting the production decline, to finding that long-lost additional pay; from drilling the wells through the most productive facies to compartmentalize the drain-hole to avoid early water-cut; the advanced log measurements are extremely helpful these days. This work tried to understand the challenges posed by the sub-surface complexities and attempts to find answers through thematic solutions. Geological and petrophysical challenges are mostly attributed to formation heterogeneity and solutions are suggested to address them. Reservoir and production challenges are also influenced by by external agencies like completions and facilities. How various measurements help in answering specific challenges raised in these fields makes the core of this work .
