About this map

Caillou Island Oil and Gas Field dominates this 1994 coastal survey, illustrating the extensive industrial footprint across the barrier islands of Terrebonne Parish. The landscape is a network of Oil Platforms, Gas Platforms, and Tanks positioned throughout the shallow waters of Caillou Bay and Timbalier Bay. These structures stand in contrast to the shifting, tide-swept reaches of Timbalier Island and Brush Island, which are characterized by expansive areas of Sand and marsh.

The mapping reflects a specific moment in Louisiana's petroleum history, showing the density of production between Caillou Pass and Little Pass Timbalier. While the northern reaches show the relative shelter of Terrebonne Bay, the southern edge of the sheet opens entirely to the Gulf of Mexico. Smaller landforms like Casse-tete Island further north indicate the fragmented nature of the coastline as it stood in the early 1990s.
