BPC has performed a live well shallow fishing and milling operation on a gas producer in Germany. The Task was to retrieve a broken Sleeve in a depth of 50 meters with the use of 2-7/8’’ VX24 DP and a 7-1/16’’ BOP Stack. After more than 70 days of different fishing, jarring and underbalanced high-speed […]
The Platform was located in the Dutch North Sea. Due to reservoir depletion, production was shut down and the gas processing facilities were removed. Most wells were drilled in the period from 1981 to 1989 with well depths ranging from 1740 to 4300 m. The objective was to Plug & Abandon (P&A) 11 wells and […]
A new well was accidentally drilled into an existing gas production well at a depth of 611m. The accident triggered an underground blow-out in which large quantities of gas were produced from a 3536m deep reservoir into the 611m formation. The drilling rig was severely damaged by the blow-out and the newly drilled hole finally […]
This gas producer well in Poland was drilled overbalance in 2011 to a depth 1528 mAH. To prevent reservoir damage caused by overbalanced drilling fluids the company decided to drill the well further in underbalance mode to a depth of 1858 mAH. Snubbing was identified as the most safe and efficient method to drill underbalance […]
During managed pressure drilling (MPD) with a conventional drilling rig into a gas bearing formation severe losses were encountered. Surface pressures up to 180 Bar were recorded. The well was temporarily killed by pumping 250 mT of LCM material and a viscous seal pill and the drilling rig was demobilized. In total 5300 m³ of […]
The well is a gas producer with a deviation of 48º that was completed with 5”completion in 1985. Well integrity problems forced the operator to shut-in the well and to plan a re-completion workover. Reservoir condition was such that killing the well would cause a significant production loss due to formation damage. HWO/Snubbing operation was […]
