Repsol made significant deepwater Mexico oil discoveries with Polok-1 and Chinwol-1 exploration wells in Block 29 in the Salina basin. Both wells confirmed high quality reservoirs with excellent properties, and consortium partners will evaluate all data for the discoveries’ appraisal plan, to be submitted to Mexico’s hydrocarbons regulator CNH before yearend.

The discoveries were drilled by Maersk’s Valiant deepwater drillship 12 km apart and 88 km from the Mexican coastline of Tabasco, in 600 m water.

The Polok-1 exploration well was drilled to 2,620 m total depth and encountered more than 200 m net oil pay from two zones in the lower Miocene. The Chinwol-1 exploration well was drilled to 1,850 m total depth and encountered more than 150 m net oil pay from three zones in the lower Pliocene.

Wireline formation testing performed on both wells showed good flow capacity in multiple stations along the Miocene and Pliocene reservoir units.

Repsol recently received approval from CNH to drill the company’s third deep water exploration in Block 10, offshore Veracruz, also to be spudded by Valiant.

Block 29 consortium partners are Repsol (30%, operator), PC Carigali Mexico Operations, the Mexican subsidiary of Petronas (28.33%), Wintershall DEA (25%), and PTTEP México E&P Ltd. (16.67%).
