... isolated within the wellbore by a packer. The lower (water sink) completion employs a submersible pump and water-drainage perforations. The submersible pump drains the accumulation of water from around the well. By doing so it prevents the water from breaking through into the oil column and adversely...

These models are calibrated and blind-tested with data collected while the PDHG is still functioning. The key to the physics-based model is our model of the gas temperature profile within the wellbore...

...Abstract Abstract While drilling and completion of deepwater wells, the cement top is usually several hundred meters below the mudline, which results in a portion of completion fluid entrapped in the technical casing annuli between wellhead and the top of cement. The temperature of the wellbore...

In reality, many reservoirs are multi-well reservoir systems and this simplified assumption may pose some drawbacks. The damaged wellbore area may truly be more exposed to the localized reservoir pressure as seen...

..., and substantial economic losses. Many blowouts start with a "kick event", where the formation pore pressure becomes greater than the wellbore pressure, causing formation fluid to flow into the wellbore and combine with the drilling fluid (i.e., mud). Detecting a kick as early as possible is key to preventing...
