Interpreting Horizontal Wells in Recon
Recon's 3-D geological interpretation environment is ideal for for horizontal well interpretation. By integrating 3-D, projected 2-D Correlation, Basemap, and Measured Depth views, Recon provides an unparallelled decision support environment for the interpretation of horizontal wells. |
A horizontal well log template in Recon's 2-D Correlation window shows gamma ray and resistivity curves for a well projected into the cross-section. Multiple picks for the red top horizon and blue base horizon can be made directly on the well log, updating the true surface profiles in real time.

Integrating Seismic with Horizontal Wells

Horizontal wells shown in Recon's 3-D view. Pick interpretations can be made directly on the well log templates in 3-D to tie the seismic horizon to the wells.

3-D Seismic accessed from Landmark SeisWorks can be displayed as a backdrop on this Recon cross-section defined along the well trajectory.

The bottom of the well template represents the well trajectory, where the true 3-D surface profiles tie to the well picks. The profiles represent stratigraphic surfaces mapped conformable to the seismic horizons and the horizontal well picks.

Using Multiple Interpretation Views to Analyze Horizontal Wells |
You can interpret horizontal wells in Recon using the 2-D correlation window, the 3-D view, and the basemap. Recon tracks your cursor location in all of its 3-D and 2-D basemap and correlation views. |
|
Recon's 2-D Well Panel display gives you a fourth option for analyzing horizontal wells using a traditional measured depth domain view. You can individually slip the logs or link them to facilitate measured depth based pick interpretation. |
|
Define intervals (e.g. facies or perforations) on horizontal and deviated wells directly in the 2-D correlation view. |
|
Create more accurate well log attribute distribution maps using horizontal wells with Recon's advanced lateral zone average interval techniques. |
|
| These features aid in making Recon the ideal environment for Interpretation While Drilling (IWD) workflows, helping you to quickly interpret real-time LWD data to improve the quality of your geological interpretation, leading to lowered risk and improved prospect development success. |

Interwell Picking on Horizontal Wells |
Making an interwell pick to position the base of the zone below the well trajectory properly constrains this horizontal well to the reservoir zone. The yellow vertical line in the 3-D view represents the 3-D tracker showing the cursor location in the 2-D correlation window.
|
You can interpret interwell picks directly in 2-D correlation (e.g. using seismic backdrops) reconciling the geological zone interpretation with complex horizontal well trajectories . |

Interval Interpretation on Horizontal Wells |
|
Using Recon you can interpret any type of interval on horizontal wells in 2-D correlation (e.g. production data or facies interpretation). The interpreted intervals are immediately displayed in 3-D. |
