The well section geometry included:
• 9⅝ inch liner shoe @ 3,388m MD at 86.5°
• 8½ inch section TD @ 4,895m MD at 92.75°
• Geosteering throughout the 1,500m lateral section
At section TD, the well was circulated bottoms up. The BHA was backreamed out of the hole to the shoe. At the shoe, a few more bottoms up operations were performed, BHA RIH to section TD, circulated, and POOH to the shoe.The PBL® Bypass Tool was activated to allow pumping of 1.15sg solid free mud to clean out the 9⅝ inch liner at 1,200
gpm. The activation ball was dropped and chased with 200 gpm flow rate to successfully activate the PBL® Tool. The mud was then circulated and displaced. Two PBL®
deactivation balls were dropped and chased with 300 gpm flow rate to deactivate the PBL® Tool, which was completed in 12 minutes.
