T3 Instructions:

T3 has a couple of new options :

  • Options|Migration has a Advanced tab for PVT and reservoir conditions
  • The Map properties dialog has an Advanced tab where you can set default reservoir and top seal properties.
  • The new 2 phase button (red/green) on the tool bar toggles between 2 phase and single phase modes
To use the 3D features:
  1. For each structure surface, you can associate a facies map (for the lateral migration along carrier bed), a top seal map (a new map type for leaking to the next surface) and a potentiometric map. (How ? just give the same age to all three maps as the structure map).
  2. If a facies or potentiometric map is not available for a structure surface, T3 will default to uniformly sand facies for carrier bed and zero hydraulic head (hydrostatic). Default top seal is assigned to each structure surface under the Advanced tab. Typically, this default top seal is what we play the most to make accumulations happen below the surface. A top seal map can be used to model laterally variable top seal conditions.
  3. Under the General tab of Migration options. Most of the options here are ignored by T3. The Max. col. height, the facies map and the potentiometric map selection here will be ignored by T3 since each surface has its own facies and potential maps. But make sure you assign enough charge volume that limits the migration. The Beep option is good when you are trying to figure out what is going on.
  4. Make sure you have correct ages for each surface and you do not have two structure maps that are the same age. T3 will use ages to determine the leaking order. If a surface is truncated by an unconformity, extend the map to merge with the unconformity surface and if the unconformity has a high enough top seal high enough it will migrate along it.
  5. You may click with the syringe tool on the current map or in the 3D viewer on any visible surface. Right mouse button click will do the same one surface only migration as in Regular Trinity. The View|Show all traps option will let you toggle seeing only the flow paths and accumulations on the current map or seeing all paths and accumulations no matter which surface you are looking at. The 3D viewer always shows all traps and flow paths.
  6. In 2 phase mode, oil would spill if trap is full. Gas will leak first if seal capacity is exceeded. This will have a significant impact on distribution of oil in 3D depending on how much latter al vs. vertical migration is going on.
  7. Also user may choose previously calculated oil and gas expulsion maps to be used for sourcing the 3d spider migration tool. All volumes are cumulatively accounted in 3D. You may subtract a migration loss (mmbls per km2) from the expulsion maps.
  8. Lost ? Feel free to call me since it is a bit complicated how this works -- My cell phone is (972)896-4112.

Trinity T3 is now officially commercial. Please download the latest from the support website here Each compnay is entitled one free upgrade from a regular Trinity license to T3. Addtional upgrades can be purcahsed at 50% discount to the commercial upgrade fee.

Why not percolation ? You may have seen the term "percolation" in earlier versions of T3. We now use uncertainty (or heterogeneity) to characterize the migration process. It is because percolation happens at pore size scale but our grid based models work at best 10's of meters. Therefore we are not modeling "percolation" although the results may "look like" "percolating" at the screen resolution. Invading a neighboring pore is not the same as invading a neighboring grid cell. Our preferred term is capillary invasion.

Project status:

  • Added paleo structure and paleo STS movie tools
  • Allowing contours on paleo-movies
Dec. 10, 2006
  • Bug fix in unconformity handling
  • Project notes feature
  • Bug fix in reading TEMIS3D file

  • Natural neighbors gridding for gridding seismic data fast and smooth.
  • Save to and recreate cross sections from visuals.
  • Lots of small improvements
Oct 1, 2006
  • Added automatic temperature correction through allochthonous salt body.
  • Added support for ArcGIS native adf files. Just drag any of the adf files in the folder in to Trinity to load the grid.
  • Shaded relief option for map view. Helps to show details not possible using contours or color map.

  • Added null value condition for ASCII grid import
  • Added R-sqaured to temperature calibration plot.
  • Allows miles instead of kft scale on map legend when distance is in feet.
Aug 6, 2006
  • Added delay behavior for trap tooltips, so it does not pop when user just moves mouse over it quickly.
  • Fixed an old problem with compaction and unconformity.
  • Added legend for the temperature time, depth and correlation plots
  • Added points on temperature correlation plots for current map, in addition to measured data. The new points will be a good visual comparing Trinity and Genesis for the current map (i.e. the source rock).
Aug 2, 2006
  • Allows unlimited thickness change layers and unlimited thickness change events (episodes) for the same layer. This is important for correctly modeling salt movement. Immediate improvements has been shown on the North Sea example, where later Oligocene movement of the salt is apparent, in addition to the main Cretaceous movement. This feature should remain in T3 for a period of time.
  • Unconformity on cross sections and burial history now does not show a brown color for the eroded section. Instead, the color of the missing formation is used and multiple eroded layers of the unconformity are not distinguished.
  • Cross plot of calculated temperature vs measured temperature from all Genesis models. The correlation responds to change in present day scaler and the temperature curve. This allows quick QC of Trinity thermal model against measurements.
July 29, 2006
  • Added temperature depth and temperature history plots on the instant burial history tool. Any Genesis input and modeled temperatures will be displayed on this if the burial history cursor is close to the well location. This allows quick QC of Trinity thermal model against Genesis models.
  • Added a html style navigation tab class for handling the switching of the different plots - to make it very intuitive
July 24, 2006
  • Fixed bug import of Temis3D files
  • Added Pressure map type and the flash calculator can pick up pressure from associated map sa age as the structure map.
  • Allows the capilarry maps (facaies and faults) to use pressure units as well as the column height units.
July 20, 2006
  • Allows to extract/digitize map values to a visual item, or scribbles

Last update 3/31/06:
  • bug fixes.
Last update 3/16/06:
  • Added several GOR correlations including two specifically for the GoM and another CGR correlation
  • Improvements in 3D spider tool.
Last update 3/3/06:
  • Miscible oil and gas migration using a simple pvt model. We can see now that how it migrates as a single phase at deep depths and dual phase at shallow depth. Gas caps form above certain depth for a given charge GOR.
  • Several bug fixes and small improvements
Last update 2/26/06:
  • Accumulations now show on cross sections
  • Two phase migration works in 3d mode - gas leaks first so shallow traps will get more gas.
  • Quick interface control to turn on /off 2 phase scenario
  • Most significant in the new algorithm is that volumes are cumulative. When a migration path joins an accumulation, volume on that path is added to the accumulation. This allows accumulation to grow and then leak or spill. This completes the bookkeeping of migration and therefore it now allows an oil and gas expelled maps to be fed for migration. Previously, the migration path simply terminates and volume is not added.
  • New 2 phase model now works in 3D spider mode and it seems much faster
  • 3D viewer window title updates when new surface is shown.
Last update 2/6/06:
  • Two phase migration allows gas flushing oil along fill and spill paths.
  • Volume book keeping in traps along migration paths.
  • Trap tips -- hovering mouse over accumulations will show volume, column heights etc.
  • Additive injection of oil and gas simulates fill and spill process through time
  • Spider map allows 2 phase migration as well
  • Numerous improvements in past months..
Last update 9/6/05:
  • Fault surfaces can be included to control vertical migration.
  • Allows creating map surface easily from a cross section
