Oliasoft WellDesign Release 3.689: New Trajectory Editor Options, DDI Visibility, and Enhanced Load Case Accuracy

What’s New:

Trajectory design

Editor type setting

A new setting is now available at both the Company and User level to define the default editor type when creating a new trajectory. Users can choose between:

• Build: Use planning methods to build your trajectory.
• List: Import a survey or create a trajectory using MD, Inc, and Azi tabular input.

Directional Difficulty Index (DDI)

Directional Difficulty Index (DDI) is now available for all Prototype and Planned designs. The DDI is displayed in the wellbore object list and can be activated through the company and user settings.

Annotations in charts

Users can now define global annotations for a wellbore within a project. These annotations can be displayed across all 2D charts (Plan View, Section View, DLS View, and Inc/Azi View).

Annotations are defined in a table located in the right-hand drawer and are referenced to the measured depth (MD) of the wellbore.

This functionality will be made available for the 3D view in the next release. 

Well schematic

Renaming of “Jetting” to “Uncemented”

For the conductor section the user has the option of toggling “Jetting” to set up an uncemented conductor.This option has now been renamed to “Uncemented”.

Well Calculator – Cement Volumes

Cement Volumes has been moved from Well Schematic to Well Calculator in the right-hand side drawer. 

Casing Design

Updates to Design Limit Plot & Von Mises Equivalent Plot

Both plots now reference the Axial Rating rather than the Yield Rating of the casing. This aligns with how triaxial safety factors are calculated.

The update will only affect Special Pipe types, where the Axial Rating differs from the Yield multiplied by the cross-sectional area of the pipe.

Update to External Load: Mud at shoe Gradient with pore pressure

The calculation has been updated for cases where the TOC is located below the previous shoe:

• From the hanger to the prior casing shoe, pressure is calculated using pore pressure at the previous shoe.

• At the top of cement (TOC), pressure equals pore pressure.

• From the previous shoe to the casing shoe, the pore pressure gradient from the TOC is applied, resulting in a pressure jump at the previous shoe.

Tooltip for PBR seal

A tooltip has been added for “PBR seal” functionality inside Load cases, making it easier for users to understand its function and impact

Techical documentation

• Technical documentation has been added for the following load cases: 
• Annular Pressure Test Internal 
• Annular Pressure Test External 
• Completion Fluid 
• Creeping Formation 
• Annular Pressure Test Internal 
• Annular Pressure Test External 
• Completion Fluid with Annular Pressure Build-Up

Temperature simulations

Animation for fracking operations

The animation for fracking operation temperature simulations has been updated to provide a clearer and more accurate visualization

Blowout & Kill

Reservoir module

The “Composition” input box containing the options PVT and Black Oil has been removed. The default option is now PVT, but users can still create a Black Oil fluid in the Reservoir module by selecting Custom under “Reservoir fluid.”

Miscellaneous

Link to Release notes in WellDesign

If a user is logged into Oliasoft WellDesign at the time of release, a link to the release notes is included in the notification dialogue box.

Bug Fixes

Temperature Simulation Rulesets

Fixed simulation chaining issue for Shut in operations in new temperature simulation rulesets.
