Hydraulic jetting multi-stage fracturing was implemented in Daniudi Gas Field Well DP19. For the poor reservoir property and little acidizing effect, fracturing stimulation was needed，but due to great change of the well track and long open hole, multi-stage fracturing was difficult to realize; its horizontal section was exposed for a long time, and wellbore sidewall collapsed,  resulting in difficulty  to run open hole packers. Petro-king provided hydraulic jetting for five-stage fracturing solution with the total gravel input up to 165.5m3. After fracturing, the daily gas production of the Well was up to 74,000m3, providing strong evidences for reservoir evaluation and reducing investment risk for the customer.
