Abstract:
The future successful development of the field by Dynamic depends upon a comprehensive process of carefully organizing the previous work, recreating complete wellbore utilization and correlation charts, and 3D seismic mapping to resolving the complex structure and stratigraphy to match the known production within each fault block and reservoir.
Unstable bottom conditions have dictated that platforms be set on top of the salt dome which has resulted in highly deviated long reach well bores that intersect bedding planes at very low angles making well log correlations between the 121 wells very difficult. Dynamic commissioned a field study in the north area with a goal of integrating well logs, paleontology, 3D seismic, and engineering data to identify and quantify new drill and sidetrack opportunities.
Measured Depth (MD) logs were digitized and used with 3D seismic depth maps to create True Vertical Thickness (TVT) logs. TVT factor and True Stratigaraphic Thickness (TST) were calculated. Arbitrary seismic lines were created along each deviated wellbore to correlate faulting and interpret horizons accurately.
This multidisciplinary field study has yielded many additional exploration and re-completion opportunities for Dynamic, and has resolved countless inconsistencies between production data and previous well correlations.
