Using whipstocks to assist with the intersect can reduce time vs. conventional methods. Traditional methods of intersecting wells involve drilling or milling...

... 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...

This case study explores various mitigating methods to acquire Measurement-While-Drilling (MWD) surveys within acceptance tolerances and where possible, to define minimum wellbore uncertainties levels depending on the wellbore trajectory relative...

... 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...

... for initial production screening along the wellbore with different reservoir conditions, which provides input to the novel multiscale 3D-2D-3D computational fluid dynamics (CFD) modeling technique to design or validate high-rate completions for the specific operating conditions. The principle of operation...

... the wellbore. Oil production from these wells was expected to suffer severely from an early gas breakthrough. 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...

... to justify the single reservoir pressure effect if it is a single-well reservoir system. 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 temperature measurement from the wellhead and other measurements during well shut-in events. 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 and cool-down...

... 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...

The experimental measurements show that hydraulic slotting is an effective stimulation manner to mitigate the skin effect near a wellbore and that a predesigned hydraulic slotting after well...

The innovative tool design makes it feasible to detect even small sand particles in adverse wellbore conditions and varied production rates, thus adding a detection of the fourth phase in an otherwise three phase production log. Opposing the fluid forces are the resulting forces that act to hold sand grains...

..., 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...

Finally, a fully integrated geohazards assessment, from the seafloor to the main reservoir, results in an optimized drilling program and is developed to minimize the impact of geohazards and drilling risks along the wellbore trajectory. inversion...
