ABSTRACT: New Exploration Opportunities in Shallow Water Offshore Louisiana Revealed by Previous Hit3DNext Hit Seismic Previous HitDataNext Hit

Undrilled economic prospects still abound in the shallow (<60') waters off Louisiana. This area which contains six of the ten largest producing oil fields in Louisiana, is covered with numerous wells and blanketed with 2D seismic Previous HitdataNext Hit. However, examination of newly available, detailed regional Previous Hit3DNext Hit seismic Previous HitdataNext Hit reveals that depleted fields and prospects previously condemned by dry holes should be re-examined. The new Previous Hit3DNext Hit seismic Previous HitdataNext Hit shows why wells missed the target and why 2D seismic Previous HitdataNext Hit are inadequate to determine drilling locations in some cases. Several case histories from this area are presented comparing 2D and Previous Hit3DNext Hit seismic Previous HitdataNext Hit, and examining well locations with respect to new Previous Hit3DNext Hit Previous HitdataNext Hit. A case history is also presented of a small independent oil company who, within one year of c mmencing acquisition of a shallow water Previous Hit3DNext Hit, drilled five commercial wildcat discoveries, each of which were located in discrete fault blocks only identifiable on the Previous Hit3DNext Hit seismic Previous HitdataNext Hit.

Large deep prospects are now apparent on new Previous Hit3DNext Hit Previous HitdataNext Hit. Previous HitDataNext Hit resolution on 2D seismic is generally poor below 3.5 seconds two-way travel time. However, improved resolution on the new Previous Hit3DNext Hit Previous HitdataTop now allows for stratigraphic sequence mapping as well as identification of structural features below 3.5 seconds. This capability now allows the accurate assessment necessary to evaluate this deep potential.
