.... Historically, methanol soaking, matrix acidizing and nitrogen unloading have proven to be successful in treating these recurring issues during the early years, but it becomes more challenging with aging wells. Therefore, this paper aims to document the undisclosed operational challenges, setbacks and lessons...

... cylinder was located above the pump preventing sand burial. The cylinder and the tube were filled with nitrogen, so the pressure was transmitted through a capillary tube to the sensor on the ground. We have tested the capillary tube measurement system in the lab, the results of the experiments showed...

... four permanent gauges were installed in the CRC-2 well in 2011 with these gauges bracketing the perforation interval. The gauges were used to monitor the injection at various stages of water, pure carbon dioxide, impure carbon dioxide and nitrogen. Observations from these gauges have allowed...
