The Eremor field is one of the twenty four marginal fields that were farmed out to indigenous oil exploration and production companies under the Federal Government initiative in accordance with the petroleum (Amendment) Decree No. 23 of 1996. It was awarded to Excel Exploration and Production, a Nigerian company that operates in the upstream sector of the oil and gas industry.

The Eremor field is located onshore, swamp terrain in Bayelsa state; Shell’s OML 46 in the South Forcados area. It is 4km North of Tunu/Kanbo field and 70km South of Warri. It covers an area of approximately 64.7 sq. /km. The field was discovered in 1978 by Well 1. Three (3) wells with one side track (Eremor-3) were drilled in 1984 while Eremor-4 was drilled in 1990. A total of five hydrocarbon bearing sands were found in the field; one of the sands is oil bearing, three are gas bearing and one consisting both gas and oil. The sands are C8.0, C9.0, D1.0, D2.0 and D3.0.

Drilling History and Status

Based on 2D seismic data interpretation, the oil-in-place volume and reserves were estimated at 12.8 and 3.9 MMSTB respectively. 3D seismic data was acquired in the area in 1996 and subsequent interpretation increased the oil-in-place and reserves from 12.8 and 3.9 MMSTB to 26.9 and 11.4 MMSTB respectively for the D.3.0 reservoir. The other hydrocarbon bearing reservoirs were either gas or undifferentiated hydrocarbon or thin layer of oil below a gas cap which were considered non-commercially viable.
