EOR Analysis – Enigma Field, Wyoming (Tensleep Formation)

Andres Fernandez at the University of Wyoming has kindly given us permission to show some of the graphics that he created using RockWorks17. Andres’ work is centered on optimizing production and revenue using the Enigma field as a case study.

Figure 1. Raster geo-locations of wellbores. Also showing placements of water injectors and oil producers, open (white) and closed (black) rasters, respectively.

Figure 2. Showing one of the highest water producing wells, cumulative water production throughout life of well. Explains injected water formation flow to North and South of field.

Figure 3. Average daily production during an 8-year period beginning 1 year prior to central-field ASP flooding.

Figure 4. Average daily production during a 5-year period beginning 1 year prior to water flood. Water flood EOR still running since 1992.

Figure 5.Average daily production of oil. Showing, also, how water injection boosted production, especially for well API4320677.

Figure 6. Average daily production of oil. Showing, also, how water injection boosted production, especially for well API4320677.

Figure 7. Used the production panel option through Google Earth/Rockworks17 due to its visual appeal. In this case showing Average Daily Water Production.

Thanks Andres!

RockWorks17 GeoBody (Contiguous Voxels w/Same G-Value) Filter Improved

(014-017) Improvements (04/06/16/JPR): The following changes have been made to the Utilities | Solid | Filters | GeoBody Filter programs:

  • (014) Improvement: The minimum number of voxels setting that was used to remove small geobodies has been replaced with the Minimum % of Voxel Volume which is far more intuitive and universal.


  • (015) New Feature: The Contiguous Units Report now includes a column that shows the percent of the model (by volume) represented by each geobody.


  • (016) New Feature: The Contiguous Units Report is now automatically sorted in descending order based on the geobody populations (see example above).

     

  • (017) Bug Fix: The program no longer includes small disconnected geobodies as parts larger geobodies when processing very large models.


RockWorks17 Find, Find Next, & Find & Replace

(011-013) Improvements & New Feature (04/04/16/JPR): The DataSheet | Search | Find & Replace option has been split into three separate options:

  • (011) Find: This is the same as the previous Find & Replace | Highlight Cell option.  It has been moved into a separate dialog to minimize the chances of replacing something when only a search was required.
  • (012) Find Next:  This new feature repeats the previous Find operation at the row below the previously found item.  The F3 shortcut greatly speeds up the process of finding additional occurrances.
  • (013) Find & Replace:  This is essentially the same as the previous Find & Replace without the Highlight-Only option (which is now accomplished with the new Find operation.
