Preowei field located in OML 130 and was discovered in 2005. Total is the operator of the field.

Total began to talk up the possibility of producing Preowei in December 2017 when, after drilling Preowei-3, it reported an addition of approximately 80 to 100 Million barrels of oil (MMbo) to the full field contingent recoverable resources, bringing them to 140 to 200MMbo.

The Preowei-3 well, drilled to a final depth of 3,235 meters, encountered approximately 50 metres net of high-quality oil-bearing sandstone reservoirs, in line with expectations. The well confirmed previous results from the Preowei-1B and Preowei-2 wells, which encountered approximately 55 metres of oil-bearing sandstone reservoir.

Preowei is expected to produce around 70,000BOEPD at peak. The field will be developed as a tie back to the Egina FPSO, the largest deepwater floater that TOTAL ever deployed.
