Hydraulic fracturing is an effective well stimulation technique to enhance hydrocarbon production by creating conductive fracture pathways. This study evaluates the application of Brittleness Index (BI) and Fracability Index (FI) for identifying optimal fracable intervals, designing fracture geometry, and assessing production improvement in Well X-183 within a volcanic formation. Rock mechanical properties were estimated from well log data using empirical correlations, followed by BI and FI evaluation and hydraulic fracture simulation with different perforation scenarios. The results identified fracable intervals at 2156– 2189 mMD and 2192–2212 mMD. Hydraulic fracturing in fracable zones produced better fracture geometry, particularly in fracture width and conductivity. Nodal analysis showed that Well X-183 production increased from 284.139 STB/d before hydraulic fracturing to 891.318 STB/d and 882.453 STB/d after stimulation in fracable scenarios, compared to 817.332 STB/d in the non-fracable scenario. The results confirm that BI and FI are effective parameters for hydraulic fracturing target selection in volcanic formations, improving fracture conductivity and well production performance.
