Petroleum system assessment has become a means to establish the temporal and spatial inter-relationships of geologic factors which result in a hydrocarbon accumulation. By analogy, it is 'geologic bookkeeping.' Our understanding of a petroleum system undergoes a series of evolutionary changes from pre-discovery through abandonment phases of a Previous HitfieldNext Hit, parallel to the development of a 'reservoir lifecycle' model. Previous HitDataNext Hit made available during each stage of a system's lifecycle (i.e., pre-discovery, discovery, development, and abandonment), when integrated with the available geologic model enhances the focus and effectiveness of the exploratory and development programs. The petroleum system evolves from a speculative to either a known or hypothetical system depending on the Previous HitdataNext Hit which become available. An Previous HitexampleNext Hit of such a lifecycle is presented for the Hatter's Pond Previous HitfieldNext Hit.

The initial exploration concept for the Hatter's Pond prospect was based on the Jay Previous HitFieldNext Hit of Florida, which had been discovered just a few years earlier. A structural anomaly was identified using seismic Previous HitdataNext Hit Hydrocarbon source rocks were assumed to be present in the Smackover Fm. as a consequence of stratigraphic analysis, although their existence had not been proven. The extent of hydrocarbon generation and preservation was estimated using numeric modeling. Initially, the reservoir objective was Smackover regressive carbonate grainstones.

Newly acquired Previous HitdataNext Hit from the Getty Peter Klein 3-14 No. 1 discovery well were merged with the original exploration model. The Previous HitdataNext Hit confirmed the presence of a source and dramatically altered the understanding of the reservoir by establishing underlying Norphlet sandstones as a primary target. Produced fluids suggested cross-formational flow.

Previous HitDataTop obtained during the development phase resulted in continuous refinement of trap geometry, connectivity of pay-zones, and development of porosity and permeability models.
