This study focuses on selecting well candidates for hydraulic fracturing in the BX Field, with the main objective of increasing oil and gas production. The BX Field, which was discovered in 1975 and started production in 2004, experienced significant production decline due to reservoir complexities, such as severe compartmentalization and low gas lift efficiency. To overcome these challenges, hydraulic fracturing was identified as a potential method to stimulate production in zones with low and medium permeability. The well candidate selection process was conducted by analyzing reservoir and well properties, and estimating production enhancement using Decline Curve Analysis and Unified Fracture Design approaches. The study also considered screening parameters such as water cut, permeability, and productivity index to determine the best well candidates. The study results showed that four wells, namely A6, A28, A33, and A42, were selected for hydraulic fracturing. Production projections after one year of hydraulic fracturing showed a significant increase in production, with the best production at A6 achieving an additional production of 5692.15 bbl and a net profit of $12,879,971.41. In conclusion, hydraulic fracturing of selected wells in the BX Field can improve production efficiency and provide substantial economic benefits. This study provides optimal well selection based on parameters such as permeability, productivity index, and water cut, as well as economic analysis to ensure the profitability of hydraulic fracturing operations. The screening parameters were modified to align with the capabilities of the wells in the BX Field. The results of this study provide insights into well selection strategies to maximize production potential in the BX Field.
