Lately, tight sand reservoir has been development extensively to increase production and adding reserve through unconventional play, following with hydraulic fracturing has become proven novel treatment and most suitable stimulation technology to increase production in a tight sandstone reservoir especially in Offshore West Java. Mostly, Hydraulic Fracturing treatment had been performing in new development wells of infill wells. Until now, the most common type of completion used in Offshore North West Java are single selective, monobore/slimhole, and openhole with perforated tubing. Completion strategy selected based on characteristic reservoir, production plan, depth of well, etc. Hydraulic fracturing treatment has been done on development wells with single selective and monobore/slimhole. Each type of completion has its own challenges, which will affect operational during hydraulic fracturing treatment. Problem that occur during operational could drive geometry of hydraulic fracturing can’t achieve target plan, which it becomes one of the key factors that will affect the rate production of the well itself. This study presents the impacts of completion type during hydraulic fracturing operation in tight sand oil reservoir in offshore North West Java focusing in KL field. This paper also share some remedial operational action to reduce problems due to completion type.
