The following table provides a sequential list of events that were important to the discovery and development of the Hebron oil field.

Hebron Development Milestones

Oil was first discovered in the Hebron Project Area in the Ben Nevis I-45 well.

The hydrocarbon that was discovered in this first round of drilling was deemed uneconomic, for the time, due to the poor reservoir quality. Test results showed uneconomic rates of oil in the Ben Nevis reservoir, and gas / condensate in the A Marker and Lower Hibernia reservoirs. The initial I-45 discovery was followed by two phases of delineation drilling.

The Hebron I-13 well was drilled to evaluate the potential of the 'Hebron horst' fault block.

The well was drilled to assess the structurally highest point of the fault block at the Hibernia and Jeanne d'Arc reservoirs, and tested oil in these reservoirs. The well also penetrated the Ben Nevis reservoir in the downthrown fault block to the south, and tested oil.

The West Ben Nevis B-75 well was drilled to evaluate the fault block between the I-45 and I-13 wells.

This well tested oil in the Ben Nevis, A Marker, and Jeanne d'Arc reservoirs.

The North Trinity H-71 was drilled.

No significant amounts of hydrocarbon found.

A second phase of delineation drilling began to test if there was an economic upside to the Hebron Project Area.
The D-94 well was drilled to test the Ben Nevis reservoir on the 'Hebron horst' fault block. The well encountered over 1 Billion barrels Stock Tank Original Oil In Place (STOOIP) and better reservoir and oil quality than observed in the I-13 well.

The D-94 well encountered the same oil water contact as identified in the I-13 well, indicating that the I-13 fault block was in communication over geologic time with the D-94 fault block.

The Ben Nevis L-55 well was drilled to evaluate the potential for higher structure and better reservoir quality in the Ben Nevis reservoir of the Ben Nevis fault block.

The well encountered higher structure than the I-45 well and a gas cap to the pool.

The Hebron M-04 well was drilled to investigate a seismic incised valley-fill feature at the top of the Jeanne d'Arc horizon (H sand), and to extend and gather data on the existing Ben Nevis, Hibernia, and Jeanne d'Arc reservoirs.

The well tested oil in the Ben Nevis and Jeanne d'Arc H sand.
