The treatment in a deepwater, frac-packed well with fiber-optic-equipped coiled tubing (CT) and a rotating, hydraulic high-pressure jetting tool achieved successful stimulation of a 500-ft-long frac-packed zone after several previous failures using different techniques. By using CT equipped with fiber optics and downhole measurement tools, engineers were able to perform a data-driven operation based on real-time bottomhole measurements and distributed-temperature surveys. This successful treatment improved productivity by 75% compared to the well before treatment.
Introduction
Diagnostic work indicated that a well had considerable skin and flow impairment. Several acid treatments had been bullheaded into the well since initial completion.
