This basin is located along the coast of the central-north part of Espírito Santo state and south part of Bahia state. The southern limit of the basin is a geological feature known as the Vitória High, that separates it from the Campos Basin, whilst the northern boundary with the Cumuruxatiba Basin is only geographic. The total basin area up to the 3,000m isobath is 123,130 km² (17,900 km² onshore) and it is covered by a recent 2D seismic spec survey.

The 489 exploration wells drilled in the basin have resulted in the discovery of 52 hydrocarbon accumulations, 47 onshore and 5 on the continental shelf. Two recent discoveries include an onshore oil that was declared commercial, resulting in the Mosquito field, and an offshore, shallow water gas accumulation in the BFRD block that is under evaluation. The basin has an original proved volume of 71 MMm³ of oil and 9,000 MMm³ of gas.

Characterization of Crude Oils
	GSI is conducting a new geochemical study of oils in the Espírito Santo basin aimed at identifying and comparing the petroleum systems that have contributed to accumulations in this petroliferous basin. Forty-five crude oils from 31 wells will be analyzed using state-of-the-art oil fingerprinting techniques to evaluate the major factors governing oil quality and quantity including: (1) source facies, (2) thermal maturity, (3) distance of migration from source to trap, (4) extent and timing of biodegradation, and (5) degree of oil mixing.

Piston Coring Survey
	A seabed piston coring surface geochemical study to identify sites of oil and gas seeps in the offshore Espirito Santo Basin of Brazil has been conducted by GEOCHEMICAL SOLUTIONS INTERNATIONAL (GSI). It is the third of several surface geochemical projects developed by GSI that evaluate the hydrocarbon potential of deep-water Brazilian marginal basins.

Integrated Study of The Petroleum Systems
	This study presents an integrated analysis of the petroleum systems of the Espírito Santo basin, eastern Brazil, based on geochemically oriented spec surveys and other geochemical studies that were recently performed by Geochemical Solutions International (GSI). The goal of this project is to provide a consistent and objective analysis of the petroleum systems of that basin to be used as an exploration tool.
