STUDY OF HYDRAULIC FRACTURING OPERATION IN THE HTFN 11 WELL, HASSI MESSAOUD FIELD

Abstract

This study focuses on the application of hydraulic fracturing supported by coiled tubing in the HTFN 11 well of the Hassi Messaoud field. Initially, the well exhibited a very low and unstable oil flow rate of about 0.8 m³/h, with a gas production of around 89.91. After the design and execution of the operation, including pre-job preparations, acid stimulation, and the main fracturing stage with 66,812 lbs of HSP 20/40 proppant, post-treatment measurements showed significant improvements: the oil flow rate increased by nearly 1.65 m³/h, reaching 2.45 m³/h, while gas production jumped to approximately 356.23. Economically, the total cost of the operation was about $192,429, with a payback period not exceeding 17 days at an oil price of $45/bbl. These results confirm the effectiveness of hydraulic fracturing in enhancing well productivity and highlight the complementary role of coiled tubing in ensuring operational success.
