During the development of seismic technology, it was critical for geophysicists to integrate their new tool into the geologic model. Today, to fully exploit the potential of 3-D and 4-D seismic, it is imperative to also integrate it with the engineering model. During the last five years, new drilling and completion techniques have proven their reliability and value. Concurrently, 3-D seismic acquisition has become the pre-eminent tool in prospect generation, especially in the offshore arena. A geophysical interpreter unaware of the latest engineering capabilities risks overlooking viable projects that he may otherwise deem unreachable or uneconomic.

The latest drilling technologies incorporate very accurate targeting capabilities utilizing "logging-while-drilling", including the acquisition of real-time sonic and density information. New drilling fluids have increased extended reach and horizontal opportunities.

Completion techniques utilizing pre-packed screen assemblies, gravel packs and conventional fracturing can enhance the value of a project to economic acceptability. This can be especially critical in the offshore venue where high lease operating expenses and large initial capital requirements can seriously impact the viability of an otherwise promising geophysical prospect.
