... value to offshore energy because it delays decommissioning. The previous financial analysis and included values in this report suggest the break even year of geothermal from repurposed offshore wellbores and platforms is between 10 and 20 years. In the past 10 years, we have seen significant growth...

... Abstract It has been known that offshore wellbores are prone to experience large deformation due to compaction of the reservoirs during the field production life. The induced compaction results in undesired effects on wellbore integrity and reservoir performance. Wellbore diameter restriction...

These challenges were recognized to be mitigated by deploying Autonomous Inflow Control Devices (AICDs), installed at reservoir interface along the horizontal section of the wells. The AICDs can manage...

The damaged wellbore area may truly be more exposed to the localized reservoir pressure as seen by the well than the apparent reservoir single value pressure assumed to determine drawdown and damage. In a multi-well reservoir system with each well-drainage area...

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 would...
