Flow Unit Characterization aided by Quantified Secondary Porosity Result from High Resolution LWD Images in Heterogeneous Carbonate Reservoir; A Novel Approach

Heera field is one of the most prolific fields in the Mumbai offshore basin in India. The field belongs to<br>one of the six tectonic blocks (Heera-Panna-Basseinn block) of Mumbai offshore basin. Carbonates are<br>by far the major contributor in terms of hydrocarbon production in this field. Presence of Vugs,<br>Fractures and Solution enhanced features makes it a real challenging job to understand the porosity<br>distribution within this reservoir. Characterizing and quantifying the complex secondary porosity profile<br>and identifying different flow unit is immensely important for production optimization and appropriate<br>completion design. The challenge of understanding the porosity heterogeneity of Carbonate reservoir<br>further increases where critical borehole condition averts the possibility of running high resolution<br>Wireline imaging tool.
