Definition
Certain structural domains or specific portions of those domains provide the greatest opportunities for exploration success. Those areas are called prospective structural fairways. In a prospective structural fairway, the structural history, trap configuration, and major elements of the hydrocarbon system combine to present a likely scenario for an economic accumulation of hydrocarbons.
Important considerations in identifying a prospective structural fairway are as follows:
- Structural style
- Tectonic overburden or denudation
- Trap evolution and timing
- Presence of source and reservoir facies
- Timing of hydrocarbon generation and migration
Assessing fairway prospectivity
The above considerations and their interdependencies, along with the following data sources, help us assess which structural fairways might be prospective:
- Regional geologic data (tops, cross sections, maps)
- Natural and productive analogs of structures
- Reconnaissance seismic data
- Potential fields
- Remote sensing data (satellite and air photo)
- Surface geologic data
- Fabric analysis
- Tectonic subsidence analysis
- Surveys for remote detection of hydrocarbons
If the structural fairway has most, if not all, of the major components needed for a viable hydrocarbon system, the next step is to identify structural leads and convert these to prospects.
