(40) VENTURI JET JUNK BASKET TO CLEANOUT HORIZONTAL YESO PRODUCERS

During the life of Yeso horizontal oil producers, well intervention and remediation is an essential step to ensure the maximum inflow volumes are being obtained and recovered volumes are matching the established production decline curves. Utilizing a Jet Junk Basket BHA with stick pipe has enabled Concho to successfully clean out a wellbore without the added cost of energized fluids and minimize the risk from getting stuck due to lost circulation. Frac sand that migrates into the wellbore during production and scale precipitation can hinder the well’s drawdown. One of the biggest challenges in being able to remove solids from the wellbore on the New Mexico Shelf is low bottom-hole reservoir pressure. Traditional cleanout methods that utilize reverse circulation and the assistance of energized fluids require higher bottom-hole reservoir pressures than that which is found on the New Mexico Shelf. The inability to maintain circulation during traditional cleanout operations has resulted in unsuccessful jobs and diminished economic efficiencies for projects in recent years prior to the application of the Venturi tool. This document describes case history and data complied over the workover results seen in 2015 and 2016. Overall, a total of 22 were successfully executed, providing an average of 35 barrels of oil per day.
