Appraisal

Phase 2: Appraisal

 

Appraisal of discovery involves drilling more wells to reduce the degree of uncertainty in the size and quality of the potential field. If an exploratory well confirms that hydrocarbons are present, additional seismic data can be collected and one or more appraisal wells may be drilled. Based on the data from this method it is possible to estimate the amounts of oil and gas in the area, and how easy / difficult it can be to produce.
