Since reaching its plateau production in January 2004, the Bijupirá Field offshore deepwater Brazil has experienced significant production declines. Analysis of the causes suggested fines migration and possibly BaSO4 scaling. Shell and service company engineers selected scale removal and matrix stimulation treatments to reestablish productivity. These were performed from a dynamically positioned drillship using Coiled Tubing (CT) in the HoriZontal OpenHole Gravel Pack (HZOHGP). This article describes the process of laboratory testing, design, simulations and project execution. The combination of offshore, deepwater, gas lift, FPSO, drillship and CT formed the first intervention of its kind.
The field came on production in August 2003 and is both gas-lifted and waterflooded. In early 2004, oil production rapidly declined to near 15,000 bopd from an initial 50,000 bopd, in part because of increasing watercuts, but mainly from declining well rates. Most of this oil came from three wells:
